Answers

Answer 1

Part 1: The correlation coefficient between the length of a person's stride and the number of steps required to walk 100 yards would likely not be close to 1 or -1.

Part 2: The correlation coefficient between the number of years of education completed and annual salary would likely not be close to -1.

Part 3: The correlation coefficient between the annual snowfall amount in a city and the number of residents would likely not be close to -1.

Part 1:

The correlation coefficient between the length of a person's stride and the number of steps required to walk 100 yards would likely not be close to 1 or -1. This is because the length of a person's stride and the number of steps are two different measurements and may not have a strong linear relationship.

Factors such as individual walking pace, terrain, and stride variability can affect the number of steps taken to cover a certain distance. Therefore, the correlation coefficient would likely fall between -1 and 1 but not be close to either extreme.

Part 2:

The correlation coefficient between the number of years of education completed and annual salary would likely not be close to -1. This is because a higher level of education generally corresponds to higher earning potential, so there tends to be a positive correlation between education and salary.

However, the correlation coefficient would also not be close to 1, as there are other factors besides education that can influence salary, such as job experience, industry, and individual performance. Therefore, the correlation coefficient would fall between -1 and 1 but not be close to either extreme.

Part 3:

The correlation coefficient between the annual snowfall amount in a city and the number of residents would likely not be close to -1. The number of residents in a city is not directly influenced by the amount of snowfall, as it is determined by various socioeconomic factors and population dynamics.

While cities in regions with heavy snowfall may have lower populations due to climate preferences, the correlation between snowfall and population is unlikely to be strong. Therefore, the correlation coefficient would not be close to -1. It would also not be close to 1, as there are other factors that influence population size. The correlation coefficient would fall between -1 and 1 but not be close to either extreme.

Answers

(a) derivative of the given function is f'(x) = O + (d/dxZ)O (b) Slope of the tangent line at x=4 is f'(4) = O + (d/dxZ)O (c) equation of the tangent line to the graph at x = 4 is y = f'(4) * x + (f(4) - 4f'(4)).

Given the function: f(x) = zVOTo find: a) Derivative of the function, b) Slope of the tangent line to the graph at x = 4, c) Equation of the tangent line to the graph at x = 4.

a) The derivative of the given function f(x) = zVO is given by;f(x) = zVO ∴ f'(x) = (zVO)'

Differentiating both sides w.r.t x= d/dx (zVO) [using the chain rule]=

[tex]zV(d/dxO) + O(d/dxV) + (d/dxZ)O (using the product rule)= z(0) + O(1) + (d/dxZ)O[/tex](using the derivative of O, which is 0) ∴

[tex]f'(x) = O + (d/dxZ)O= O + O(d/dxZ) [using the product rule]= O + (d/dxZ)O= O + (d/dxZ)O [as (d/dxZ)[/tex] is the derivative of Z w.r.t x]

Thus, the derivative of the given function is f'(x) = O + [tex](d/dxZ)O[/tex]

b) Slope of the tangent line to the graph at x = 4= f'(4) [as we need the slope of the tangent line at x=4]= O + (d/dxZ)O [putting x = 4]∴ Slope of the tangent line at x=4 is f'(4) = O + (d/dxZ)O

c) Equation of the tangent line to the graph at x = 4The point is (4, f(4)) on the curve whose tangent we need to find. The slope of the tangent we have already found in part

(b).Let the equation of the tangent line be given by: y = mx + c, where m is the slope of the tangent, and c is the y-intercept of the tangent.To find c, we need to substitute the values of (x, y) and m in the equation of the tangent.∴ y = mx + c... (1)Putting x=4, y= f(4) and m=f'(4) in (1), we get:[tex]f(4) = f'(4) * 4 + c∴ c = f(4) - 4f'(4)[/tex]

Hence, the equation of the tangent line to the graph at x = 4 is:[tex]y = f'(4) * x + (f(4) - 4f'(4))[/tex]

Thus, the derivative of the function f(x) = zVO is O + (d/dxZ)O. The slope of the tangent line to the graph at x = 4 is f'(4) = O + (d/dxZ)O. And, the equation of the tangent line to the graph at x = 4 is y = f'(4) * x + (f(4) - 4f'(4)).

how many different values of lll are possible for an electron with principal quantum number nnn_1 = 4? express your answer as an integer.

Answers

For an electron with a principal quantum number n = 4, there are 7 different possible values for the azimuthal quantum number l.

Explanation:

The principal quantum number (n) describes the energy level or shell of an electron. The azimuthal quantum number (l) specifies the shape of the electron's orbital within that energy level. The values of l range from 0 to (n-1).

In this case, n = 4. Therefore, the possible values of l can be calculated by substituting n = 4 into the range formula for l.

Range of l: 0 ≤ l ≤ (n-1)

Substituting n = 4 into the formula, we have:

Range of l: 0 ≤ l ≤ (4-1)

0 ≤ l ≤ 3

Thus, the possible values of l for an electron with n = 4 are 0, 1, 2, and 3. Therefore, there are 4 different values of l that are possible for an electron with principal quantum number n = 4.

Problem 1. point) Consider the curve defined by the equation y=6x' + 2x set up an integral that represents the length of curve from the point (3,180) to the port (1.1544) de Note. In order to get crea

Answers

Evaluating this integral, we have:

L = [√(65)x] evaluated from 3 to 1.1544

L = √(65)(1.1544 - 3)

L ≈ -9.1428

To find the length of the curve defined by the equation y = 6x' + 2x between the points (3, 180) and (1, 154.4), we can use the arc length formula for a curve given by y = f(x):

L = ∫[a,b] √(1 + (f'(x))^2) dx

In this case, the function is y = 6x' + 2x. Let's find its derivative first:

dy/dx = d/dx (6x' + 2x)

      = 6 + 2

      = 8

Now we have the derivative, which we can substitute into the arc length formula:

L = ∫[a,b] √(1 + (f'(x))^2) dx

 = ∫[a,b] √(1 + (8)^2) dx

 = ∫[a,b] √(1 + 64) dx

 = ∫[a,b] √(65) dx

To determine the limits of integration [a, b], we need to find the x-values that correspond to the given points. For the first point (3, 180), we have x = 3. For the second point (1, 154.4), we have x = 1.1544.

Therefore, the integral representing the length of the curve is:

L = ∫[3, 1.1544] √(65) dx

You can evaluate this integral numerically using appropriate methods, such as numerical integration techniques or software like Wolfram Alpha, to find the length of the curve between the given points.

To find the length of the curve between the points (3, 180) and (1, 154.4), we set up the integral as follows:

as the tides change, the water level in a bay varies sinusoidally. at high tide today at 8 a.m., the water level was 15 feet; at low tide, 6 hours later at 2 pm, it was 3 feet. how fast, in feet per hour, was the water level dropping at noon today?

Answers

The water level dropped from 15 feet at 8 A.M. to 3 feet at 2 P.M. The time interval between these two points is 6 hours. Therefore, the rate of change of the water level at noon was 2 feet per hour.

By analyzing the given information, we can deduce that the period of the sinusoidal function is 12 hours, representing the time from one high tide to the next. Since the high tide occurred at 8 A.M., the midpoint of the period is at 12 noon. At this point, the water level reaches its average value between the high and low tides.

To find the rate of change at noon, we consider the interval between 8 A.M. and 2 P.M., which is 6 hours. The water level dropped from 15 feet to 3 feet during this interval. Thus, the rate of change is calculated by dividing the change in water level by the time interval:

Rate of change = (Water level at 8 A.M. - Water level at 2 P.M.) / Time interval

Rate of change = (15 - 3) / 6

Rate of change = 12 / 6

Rate of change = 2 feet per hour

Therefore, the water level was dropping at a rate of 2 feet per hour at noon.

Eight Tires Of Different Brands Are Ranked From 1 To 8 (Best To Worst) According To Mileage Performance. Suppose Four Of These Tires Are Chosen At Random By A Customer. Let Y Denote The Actual Quality Rank Of The Best Tire Selected By The Customer. Find The Probabilities Associated With All Of The Possible Values Of Y. (Enter Your Probabilities As

Answers

The probabilities associated with all possible values of Y are:

P(Y = 1) = 1/2

P(Y = 2) = 1/2

P(Y = 3) = 1/2

P(Y = 4) = 1/8

To find the probabilities associated with all possible values of Y, consider the different scenarios of tire selection.

Since there are eight tires and four are chosen at random, the possible values of Y range from 1 to 4.

1. Y = 1 (The best tire is selected)

  In this case, the best tire can be selected in any of the four positions (1st, 2nd, 3rd, or 4th). The remaining three tires can be any of the remaining seven tires. Therefore, the probability is:

  P(Y = 1) = (4/8) * (7/7) * (6/6) * (5/5) = 1/2

2. Y = 2 (The second-best tire is selected)

  In this case, the second-best tire can be selected in any of the four positions (1st, 2nd, 3rd, or 4th). The best tire is not selected, so it can be any of the remaining seven tires. The remaining two tires can be any of the remaining six tires. Therefore, the probability is:

  P(Y = 2) = (4/8) * (7/7) * (6/6) * (5/5) = 1/2

3. Y = 3 (The third-best tire is selected)

  In this case, the third-best tire can be selected in any of the four positions (1st, 2nd, 3rd, or 4th). The best tire is not selected, so it can be any of the remaining seven tires. The second-best tire is also not selected, so it can be any of the remaining six tires. The remaining tire can be any of the remaining five tires. Therefore, the probability is:

  P(Y = 3) = (4/8) * (7/7) * (6/6) * (5/5) = 1/2

4. Y = 4 (The fourth-best tire is selected)

  In this case, the fourth-best tire is selected in the only position left. The best tire is not selected, so it can be any of the remaining seven tires. The second-best and third-best tires are also not selected, so they can be any of the remaining six tires. Therefore, the probability is:

  P(Y = 4) = (1/8) * (7/7) * (6/6) * (5/5) = 1/8

In summary, the probabilities associated with all possible values of Y are:

P(Y = 1) = 1/2

P(Y = 2) = 1/2

P(Y = 3) = 1/2

P(Y = 4) = 1/8

Answers

The answer is: ||a × d|| = √(24^2 + 12^2 + (-12)^2) = √(576 + 144 + 144) = √864 = 12√6.

To calculate the given expressions involving vectors, let's go step by step:

a + b:

We have a = (3, -6) and b = (0, 7).

Adding the corresponding components, we get:

a + b = (3 + 0, -6 + 7) = (3, 1).

||a||:

Using the formula for the magnitude of a vector, we have:

||a|| = √(3^2 + (-6)^2) = √(9 + 36) = √45 = 3√5.

||a - b||:

Subtracting the corresponding components, we get:

a - b = (3 - 0, -6 - 7) = (3, -13).

Using the formula for the magnitude, we have:

||a - b|| = √(3^2 + (-13)^2) = √(9 + 169) = √178.

a · c:

We have a = (3, -6) and c = (5, 9, 8).

Using the dot product formula, we have:

a · c = 3*5 + (-6)*9 + 0*8 = 15 - 54 + 0 = -39.

||a × d||:

We have a = (3, -6) and d = (2, 0, 4).

Using the cross product formula, we have:

a × d = (3, -6, 0) × (2, 0, 4).

Expanding the cross product, we get:

a × d = (0*(-6) - 4*(-6), 4*3 - 2*0, 2*(-6) - 0*3) = (24, 12, -12).

Using the formula for the magnitude, we have:

||a × d|| = √(24^2 + 12^2 + (-12)^2) = √(576 + 144 + 144) = √864 = 12√6.

In this solution, we performed vector calculations involving the given vectors a, b, c, and d. We added the vectors a and b by adding their corresponding components.

We calculated the magnitude of vector a using the formula for vector magnitude. We found the magnitude of the difference between vectors a and b by subtracting their corresponding components and calculating the magnitude.

We found the dot product of vectors a and c using the dot product formula. Finally, we found the cross product of vectors a and d by applying the cross product formula and calculated its magnitude using the formula for vector magnitude.

Evaluate the integral. (Use C for the constant of integration.) 3x cos(8x) dx

Answers

To evaluate the integral ∫3x cos(8x) dx, we need to find an antiderivative of the given function. The result will be expressed in terms of x and may include a constant of integration, denoted by C.

To evaluate the integral, we can use integration by parts, which is a technique based on the product rule for differentiation. Let's consider the function u = 3x and dv = cos(8x) dx. Taking the derivative of u, we get du = 3 dx, and integrating dv, we obtain v = (1/8) sin(8x).

Using the formula for integration by parts: ∫u dv = uv - ∫v du, we can substitute the values into the formula:

∫3x cos(8x) dx = (3x)(1/8) sin(8x) - ∫(1/8) sin(8x) (3 dx)

Simplifying this expression gives:

(3/8) x sin(8x) - (3/8) ∫sin(8x) dx

Now, integrating ∫sin(8x) dx gives:

(3/8) x sin(8x) + (3/64) cos(8x) + C

Thus, the evaluated integral is:

∫3x cos(8x) dx = (3/8) x sin(8x) + (3/64) cos(8x) + C, where C is the constant of integration.

Answers

The centroid of the region bounded by the curves y = 2 sin(3x), y = 2 cos(3x), x = 0, and x = 12 is approximately (x, y) = (6, 0).

To find the centroid of the region bounded by the given curves, we need to determine the x-coordinate (x-bar) and y-coordinate (y-bar) of the centroid. The x-coordinate of the centroid is given by the formula:

x-bar = (1/A) * ∫[a,b] x * f(x) dx,

where A represents the area of the region and f(x) is the difference between the upper and lower curves.

Similarly, the y-coordinate of the centroid is given by:

y-bar = (1/A) * ∫[a,b] 0.5 * [f(x)]^2 dx,

where 0.5 * [f(x)]^2 represents the squared difference between the upper and lower curves.

Integrating these formulas over the given interval [0, 12] and calculating the areas, we find that the x-coordinate (x-bar) of the centroid is equal to 6, while the y-coordinate (y-bar) evaluates to 0.

Answers

To find dx/dy using logarithmic differentiation for the equation x²√3x² + 2y = (x + 1)³, we take the natural logarithm of both sides, differentiate using the chain rule, and solve for dy/dx. The resulting expression for dy/dx is y' = 3(x²√3x² + 2y)/(2x√3x² + 2(x + 1)y).

To find dx/dy using logarithmic differentiation for the equation x²√3x² + 2y = (x + 1)³, we take the natural logarithm of both sides, apply logarithmic differentiation, and solve for dx/dy.

Let's start by taking the natural logarithm of both sides of the given equation: ln(x²√3x² + 2y) = ln((x + 1)³).

Using the properties of logarithms, we can simplify this equation to 1/2ln(x²) + 1/2ln(3x²) + ln(2y) = 3ln(x + 1).

Next, we differentiate both sides of the equation with respect to x using the chain rule. For the left side, we have d/dx[1/2ln(x²) + 1/2ln(3x²) + ln(2y)] = d/dx[ln(x²√3x² + 2y)] = 1/(x²√3x² + 2y) * d/dx[(x²√3x² + 2y)]. For the right side, we have d/dx[3ln(x + 1)] = 3/(x + 1) * d/dx[(x + 1)].

Simplifying the differentiation on both sides, we get 1/(x²√3x² + 2y) * (2x√3x² + 2y') = 3/(x + 1).

Now, we can solve this equation for dy/dx (which is equal to dx/dy). First, we isolate y' (the derivative of y with respect to x) by multiplying both sides by (x²√3x² + 2y). This gives us 2x√3x² + 2y' = 3(x²√3x² + 2y)/(x + 1).

Finally, we can solve for y' (dx/dy) by dividing both sides by 2 and simplifying: y' = 3(x²√3x² + 2y)/(2x√3x² + 2(x + 1)y).

+ +... Σ 0.3 = 1+(0.3)+ (0.3)2 (0.3) (0.3) Given 2! 3! in=0 n!' what degree Maclaurin polynomial is required so that the error in the approximation is less than 0.0001? A. n=6 B. n=3 C. n=5 D.n=4

Answers

The degree of the Maclaurin polynomial required is n = 6.

The given series is Σ0.3^n, where n starts from 0. We want to determine the degree of the Maclaurin polynomial required to approximate this series with an error less than 0.0001.

To find the degree of the Maclaurin polynomial, we need to consider the error bound using Taylor's inequality. The error bound is given by the (n+1)th derivative of the function evaluated at a point multiplied by (x-a)^(n+1), divided by (n+1)!. In this case, a is 0, and we want the error to be less than 0.0001.

Let's consider the (n+1)th derivative of the function f(x) = 0.3^x. Taking derivatives, we have:

f'(x) = ln(0.3) * 0.3^x

f''(x) = ln(0.3)^2 * 0.3^x

f'''(x) = ln(0.3)^3 * 0.3^x

We can observe that as we take higher derivatives, the value of ln(0.3)^k * 0.3^x decreases for any positive integer k. To ensure the error is less than 0.0001, we need to find the smallest value of n such that:

|f^(n+1)(x)| * (0.3)^(n+1) / (n+1)! < 0.0001

Since the value of ln(0.3) is negative, we can take its absolute value. Solving this inequality for n, we find:

|ln(0.3)^(n+1) * 0.3^(n+1)| / (n+1)! < 0.0001

Now, we can evaluate the inequality for different values of n to determine the smallest value that satisfies the condition.

After evaluating the inequality for n = 3, n = 4, n = 5, and n = 6, we find that only n = 6 satisfies the condition, making the error in the approximation less than 0.0001. Therefore, the degree of the Maclaurin polynomial required is n = 6.

In this solution, we are given the series Σ0.3^n, and we want to determine the degree of the Maclaurin polynomial required to approximate the series with an error less than 0.0001.

Using Taylor's inequality, we calculate the (n+1)th derivative of the function and observe that the magnitude of the derivative decreases as we take higher derivatives.

To ensure the error is less than 0.0001, we set up an inequality and solve for the smallest value of n that satisfies the condition. After evaluating the inequality for n = 3, n = 4, n = 5, and n = 6, we find that only n = 6 satisfies the condition, indicating that a degree 6 Maclaurin polynomial is required for the desired level of accuracy.

Therefore, the answer is (A) n = 6.

Solve the differential equation. (Use C for any needed constant. Your response should be in the form 'g(y)=f(0)'.) e sin (0) de y sece) dy

Answers

Answer:

The solution to the differential equation is:

g(y) = -sec(e) x - f(0)

Step-by-step explanation:

To solve the given differential equation:

(e sin(y)) dy = sec(e) dx

We can separate the variables and integrate:

∫ (e sin(y)) dy = ∫ sec(e) dx

Integrating the left side with respect to y:

-g(y) = sec(e) x + C

Where C is the constant of integration.

To obtain the final solution in the desired form 'g(y) = f(0)', we can rearrange the equation:

g(y) = -sec(e) x - C

Since f(0) represents the value of the function g(y) at y = 0, we can substitute x = 0 into the equation to find the constant C:

g(0) = -sec(e) (0) - C

f(0) = -C

Therefore, the solution to the differential equation is:

For what value of the constant c is the function f defined below continuous on (-00,00)? f(x) = {2-c if y € (-0,2) y cy+7 if ye 2,00) - С

Answers

The function f is continuous on the interval (-∞, ∞) if c = 2. This is because this value of c ensures that the limits of f as x approaches 2 and as x approaches -0 from the left are equal to the function values at those points.

To determine the value of the constant c that makes the function f continuous on the interval (-∞, ∞), we need to consider the limit of f as x approaches 2 and as x approaches -0 from the left.

First, let's consider the limit of f as x approaches 2 from the left. This means that y is approaching 2 from values less than 2. In this case, the function takes the form cy + 7, and we need to ensure that this expression approaches the same value as f(2), which is 2-c. Therefore, we need to solve for c such that:

lim y→2- (cy + 7) = 2 - c

Using the limit laws, we can simplify this expression:

lim y→2- cy + lim y→2- 7 = 2 - c

Since lim y→2- cy = 2-c, we can substitute this into the equation:

2-c + lim y→2- 7 = 2 - c

lim y→2- 7 = 0

Therefore, we need to choose c such that:

2 - c = 0

c = 2

Next, let's consider the limit of f as x approaches -0 from the left. This means that y is approaching -0 from values greater than -0. In this case, the function takes the form 2 - c, and we need to ensure that this expression approaches the same value as f(-0), which is 2 - c. Since the limit of f(x) as x approaches -0 from the left is equal to f(-0), the function is already continuous at this point, and we do not need to consider any additional values of c.

Answers

To solve the indefinite integral ∫(e²x + 2)² dx, we can perform a substitution by letting U = e²x + 2. This transforms the integral into ∫U² du, which can be integrated using the power rule of integration.

Let's start by performing the substitution:

Let U = e²x + 2, then du = 2e²x dx.

The integral becomes ∫(e²x + 2)² dx = ∫U² du.

Now we can integrate ∫U² du using the power rule of integration. The power rule states that the integral of xⁿ dx is (xⁿ⁺¹ / (n + 1)) + C, where C is the constant of integration.

Applying the power rule, we have:

∫U² du = (U³ / 3) + C.

Substituting back U = e²x + 2, we get:

∫(e²x + 2)² dx = ((e²x + 2)³ / 3) + C.

Answers

The region that is bounded by the graph of the function g(y) = -² -- 1, the y-axis, y = -1, and y = 2.The volume of the solid of revolution when region Q is rotated around the y-axis is 3π.

To find the volume of the solid of revolution when region Q is rotated around the y-axis, we can use the disk method. The region Q is bounded by the graph of the function g(y) = y^2 – 1, the y-axis, y = -1, and y = 2.

To apply the disk method, we divide region Q into infinitesimally thin vertical slices. Each slice is considered as a disk of radius r and thickness Δy. The volume of each disk is given by πr^2Δy.

The radius of each disk is the distance from the y-axis to the curve g(y), which is simply the value of y. Therefore, the radius r is y.

The thickness Δy is the infinitesimal change in y, so we can express it as dy.

Thus, the volume of each disk is πy^2dy.

To find the total volume, we integrate the volume of each disk over the range of y-values for region Q, which is from y = -1 to y = 2:

V = ∫[from -1 to 2] πy^2dy.

Evaluating this integral, we get:

V = π∫[from -1 to 2] y^2dy

 = π[(y^3)/3] [from -1 to 2]

 = π[(2^3)/3 – (-1^3)/3]

 = π[8/3 + 1/3]

 = π(9/3)

 = 3π.

Given the vectors v = (1, - 3), v = (- 2, - 1). Determine whether the given vectors form a basis for R2. Show your work.

Answers

To determine whether the given vectors v = (1, -3) and v = (-2, -1) form a basis for R2, we need to check if they are linearly independent and span the entire R2 space.

To check for linear independence, we set up a linear combination equation where the coefficients of the vectors are unknown (let's call them a and b). We equate this linear combination to the zero vector (0, 0) and solve for a and b:

a(1, -3) + b(-2, -1) = (0, 0)

Simplifying this equation gives two simultaneous equations:

a - 2b = 0

-3a - b = 0

Solving these equations simultaneously, we find that a = 0 and b = 0, indicating that the vectors are linearly independent.

To check for span, we need to verify if any vector in R2 can be expressed as a linear combination of the given vectors. Since the vectors are linearly independent, they span the entire R2 space.

Therefore, the given vectors v = (1, -3) and v = (-2, -1) form a basis for R2 as they are linearly independent and span the entire R2 space.

Answers

The radius of convergence, R, for both f(x) and f'(x) is the distance from the center of the series expansion (which is x = 0) to the nearest singularity, which is x = -2. Therefore, the radius of convergence, R, is 2.

(a) The power series representation for f(x) = 1 / (2 + x)² is:

f(x) = Σn = 0 to ∞ (-1)ⁿ* (n+1) * xⁿ

The coefficients in the series can be found by differentiating the function f(x) term by term and evaluating at x = 0. Taking the derivative of f(x), we have:

f'(x) = 2 * Σn = 0 to ∞ (-1)ⁿ * (n+1) * xⁿ

To find the coefficients, we differentiate each term of the series and evaluate at x = 0. The derivative of xⁿ is n * xⁿ⁻¹, so:

f'(x) = 2 * Σn = 0 to ∞ (-1)ⁿ* (n+1) * n * xⁿ⁻¹

Evaluating at x = 0, all the terms in the series except the first term vanish, so we have:

f'(x) = 2 * (-1)⁰ * (0+1) * 0 * 0⁻¹ = 0

Thus, the power series representation for f'(x) = 1 / (2 + x)³ is:

f'(x) = 0

The radius of convergence, R, for both f(x) and f'(x) is the distance from the center of the series expansion (which is x = 0) to the nearest singularity, which is x = -2. Therefore, the radius of convergence, R, is 2.

Using product rule, the derivative of the function f(x) = 6xe²ˣ is f'(x) = 6e²ˣ + 12xe²ˣ.

What is the derivative of the function?

To find the derivative of the function f(x) = 6xe²ˣ we can use the product rule and the chain rule. The product rule states that if we have two functions u(x) and v(x), then the derivative of their product is given by (u(x)v(x))' = u'(x)v(x) + u(x)v'(x).

In this case, let's consider u(x) = 6x and v(x) = e²ˣ. Applying the product rule, we have:

f'(x) = (u(x)v(x))'

f'(x) = u'(x)v(x) + u(x)v'(x).

Now, let's compute the derivatives of u(x) and v(x):

u'(x) = d/dx (6x)

u'(x) = 6.

v'(x) = d/dx (e²ˣ)

v'(x) = 2e²ˣ

Substituting these derivatives into the product rule formula, we get:

f'(x) = 6 * e²ˣ + 6x * 2e²ˣ.
