Answer:

Missing side = 15

Yes.  The side lengths 39, 36, and 15 form a Pythagorean triple.

Step-by-step explanation:

Value of missing side:

Because this is a right triangle, we can find the missing side using the Pythagorean theorem, which is

a^2 + b^2 = c^2, where

Thus, we can plug in 36 for a and 39 for c, allowing us to solve for b, the value of the missing side:

36^2 + b^2 = 39^2

1296 + b^2 = 1521

b^2 = 225

b = 15

Pythagorean triple question:

The numbers 39, 36, and 15 are Pythagorean triples:

Since 36^2 + 15^2 = 39^2, the three numbers are a Pythagorean triple.  You can see it better when we simplify:

36^2 + 15^2 = 39^2

1296 + 225 = 1521

I've attached a graph of the area between the two curves in case it helps you understand better!

The slope of this line segment represents the difference quotient (f(1+h) - f(1))/h, which is the expression we use to find the derivative using the limit definition.

a) Calculation of the derivative using the limit definition is given below:

f'(x) = lim { f(x+h) - f(x) }/h

Here, f(x) = 2x² - 1

Hence, f(x + h) = 2(x+h)² - 1= 2(x² + 2xh + h²) - 1= 2x² + 4xh + 2h² - 1f(x) = 2x² - 1

Putting these values in the formula of the derivative, we get

f'(x) = lim { f(x+h) - f(x) }/h= lim { 2x² + 4xh + 2h² - 1 - 2x² + 1 }/h= lim { 4xh + 2h² }/h= lim 2h(2x + h)/h= lim 2(2x + h) as h → 0

Since the limit exists, we can substitute h = 0, which gives

f'(x) = 4xHence, f'(1) = 4

b) The graph of the function y = 2x² - 1 is shown below:

The tangent line to the curve at x = 1 is given by

y - f(1) = f'(1) (x - 1)y - 1 = 4(x - 1)

Simplifying, we get

y = 4x - 3

The variable h is shown in the graph as a small line segment originating from the point (1, 1) and terminating at the point (1+h, 2(1+h)² - 1). The slope of this line segment represents the difference quotient (f(1+h) - f(1))/h, which is the expression we use to find the derivative using the limit definition.

The general indefinite integral of (11 - 6t)(8 + t^2) dt is (4t^4 - 6t^3 + 44t - 33ln|t| + C), where C is the constant of integration.

To solve this integral, we can distribute the terms inside the parentheses:

∫ (11 - 6t)(8 + t^2) dt = ∫ (88 + 11t^2 - 48t - 6t^3) dt

Next, we integrate each term separately. The integral of a constant multiplied by a function is simply the constant times the integral of the function, so we have:

∫ (88 + 11t^2 - 48t - 6t^3) dt = 88∫ dt + 11∫ t^2 dt - 48∫ t dt - 6∫ t^3 dt

The integral of dt is simply t, so we get:

= 88t + 11∫ t^2 dt - 48∫ t dt - 6∫ t^3 dt

To integrate each term involving t, we use the power rule of integration. The power rule states that the integral of t^n dt is (t^(n+1))/(n+1). Applying the power rule, we have:

= 88t + 11(t^3/3) - 48(t^2/2) - 6(t^4/4) + C

Simplifying further, we get:

= 88t + (11/3)t^3 - 24t^2 - (3/2)t^4 + C

Finally, we can rewrite the answer in descending order of powers of t:

= (4t^4 - 6t^3 - 24t^2 + 88t) - (3/2)t^4 + C

And this is the general indefinite integral of (11 - 6t)(8 + t^2) dt.

To find the slope of the secant line connecting the points (-3, f(-3)) and (-1, f(-1)), we need to calculate the average rate of change of the function over that interval. The average rate of change is given by the formula:

Average rate of change = (f(b) - f(a)) / (b - a)

where (a, f(a)) and (b, f(b)) are the coordinates of the two points on the interval.

In this case, a = -3, b = -1, f(a) = f(-3), and f(b) = f(-1). Let's calculate these values first:

f(-3) = 2(-3)³ + 3(-3) = -54 - 9 = -63

f(-1) = 2(-1)³ + 3(-1) = -2 - 3 = -5

Now we can substitute these values into the formula for the average rate of change:

Average rate of change = (-5 - (-63)) / (-1 - (-3))

                     = (-5 + 63) / (-1 + 3)

                     = 58 / 2

                     = 29

Therefore, the exact value of the slope of the secant line connecting (-3, f(-3)) and (-1, f(-1)) is 29.

If you graduate, work full time for 10 years, and invest $1,300 per month with a return rate of 6.5%, you can expect to have saved approximately $238,165.15.

Assuming you consistently invest $1,300 per month for 10 years, the total amount invested would be $156,000 ($1,300 x 12 months x 10 years). With an expected return rate of 6.5%, your investments would grow over time.

To calculate the final savings, we need to consider compound interest. Compound interest is the interest earned not only on the initial investment but also on the accumulated interest from previous periods. Using the compound interest formula A = P(1 + r/n)^(nt), where A is the final amount, P is the principal (initial investment), r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years.

In this case, the principal is $156,000, the annual interest rate is 6.5%, and the compounding is assumed to be done monthly (n = 12). Plugging in these values into the formula, we get A = $156,000(1 + 0.065/12)^(12*10). After solving the equation, the final savings amount would be approximately $238,165.15.

It's important to note that this calculation assumes a consistent monthly investment, a fixed return rate, and no additional contributions or withdrawals during the 10-year period. Market fluctuations, taxes, and other factors may also impact the actual savings amount.

The equation of the line tangent to the curve 2e^y  = x + y at the point (2,0) is y = -x + 2.

To find the equation of the tangent line, we need to find the slope of the tangent line at the given point. First, we differentiate the equation 2e^y = x + y with respect to x using implicit differentiation.

Taking the derivative of both sides with respect to x, we get: 2e^y(dy/dx) = 1 + dy/dx.

Simplifying the equation, we have: dy/dx = (1 - 2e^y)/(2e^y - 1).

Now, substitute the coordinates of the given point (2,0) into the equation to find the slope of the tangent line: dy/dx = (1 - 2e⁰)/(2e⁰ - 1) = -1.

The slope of the tangent line is -1. Now, using the point-slope form of a line, we have: y - y1 = m(x - x1),

where (x1, y1) is the point (2,0) and m is the slope -1. Substituting the values, we get: y - 0 = -1(x - 2), which simplifies to: y = -x + 2. Thus, the equation of the tangent line in slope-intercept form is y = -x + 2.

So, the probability of rolling two consonants is 1/1.

The probability of rolling two consonants when rolling a six-sided cube with the letters S, O, L, V, E and D, we first need to determine the number of consonants and the total number of outcomes.

The given letters are S, O, L, V, E, and D. Out of these, the consonants are S, L, V and D.

So, there are 4 consonants in total.

The cube has 6 sides, meaning there are 6 possible outcomes when rolling it.

To find the probability, we divide the number of favorable outcomes (rolling two consonants) by the total number of outcomes.

The number of favorable outcomes is given by the number of ways we can choose 2 consonants out of the 4 available.

This can be calculated using combinations, denoted as "C."

The number of ways to choose 2 consonants out of 4 is written as C(4, 2) or 4C2.

C(4, 2) = 4! / (2! × (4 - 2)!)

= 4! / (2! × 2!)

= (4 × 3 × 2 × 1) / (2 × 1 × 2 × 1)

= 6

So, there are 6 ways to choose 2 consonants out of the 4 available.

The total number of outcomes is 6, as there are 6 sides on the cube.

Now, we can calculate the probability:

Probability of rolling two consonants = Number of favorable outcomes / Total number of outcomes

Probability of rolling two consonants = 6 / 6 = 1

The probability of rolling two consonants is 1.

(b) By considering the sequence {an} = {cos(nθ)} and the partial sums sn = Σk=1 to n cos(kθ), all solutions of the equation 8b - s(a - 1) = 0 are found.

(a) To show that the equation 2sin(θ)cos(θ)k + 0 - sin(k(x-1)) = 0 holds, we can simplify the expression. First, we can rewrite 2sin(θ)cos(θ) as sin(2θ). Next, we have sin(k(x-1)) - sin(k(x-1)) = 0 since the two terms cancel out. Therefore, the equation simplifies to sin(2θ)k = 0, which is true when either sin(2θ) = 0 or k = 0.

(b) Considering the sequence {an} = {cos(nθ)} and the partial sums sn = Σk=1 to n cos(kθ), we can substitute these values into the equation 8b - s(a - 1) = 0. This gives us 8b - (cos(aθ) - 1) = 0.

A random sample of 100 observations from a normal population has a sample variance of 220. We need to test, with a significance level of α = 0.05, whether we can infer that the population variance differs from 300.

To test whether the population variance differs from a hypothesized value of 300, we can use the chi-square test. In this case, we calculate the test statistic as (n-1)s^2/σ^2, where n is the sample size, s^2 is the sample variance, and σ^2 is the hypothesized population variance.

In our case, the sample variance is 220, and the hypothesized population variance is 300. The sample size is 100. Thus, the test statistic is (100-1)*220/300.

We can compare this test statistic to the critical value from the chi-square distribution with degrees of freedom equal to n-1. With a significance level of α = 0.05, we find the critical value from the chi-square distribution table.

If the test statistic is greater than the critical value, we reject the null hypothesis that the population variance is 300, indicating that there is evidence that the population variance differs from 300. Conversely, if the test statistic is less than or equal to the critical value, we fail to reject the null hypothesis and do not have enough evidence to conclude that the population variance is different from 300.

In conclusion, by comparing the calculated test statistic to the critical value, we can determine whether we can infer that the population variance differs from the hypothesized value of 300, with a significance level of α = 0.05.

Given statement solution is :- Unknown side lengths in your triangle using the Perpendicular Bisector Theorem and the Isosceles Triangle Theorem.

Let's start with the Perpendicular Bisector Theorem. According to this theorem, if a line segment is the perpendicular bisector of a side of a triangle, then it divides that side into two congruent segments. This means that the lengths of the two segments formed by the perpendicular bisector are equal.

Now, let's move on to the Isosceles Triangle Theorem. In an isosceles triangle, two sides are congruent. This means that the lengths of the two equal sides are the same.

To solve for unknown side lengths, we can use these theorems in combination. Here's a step-by-step process:

Identify the triangle you are working with and label the sides and angles accordingly. Let's call the triangle ABC, with side lengths AB, BC, and AC.

Determine if any of the sides are bisected by a perpendicular bisector. If so, label the point where the bisector intersects the side as D. This will divide the side into two congruent segments, BD and DC.

Apply the Perpendicular Bisector Theorem to set up an equation. Since BD and DC are congruent, you can write an equation stating that BD = DC.

Identify if the triangle is isosceles. If so, you can use the Isosceles Triangle Theorem to set up another equation. This equation will state that the lengths of the two congruent sides are equal, for example, AB = AC.

Now you have a system of equations that you can solve simultaneously. Substitute the values you know into the equations and solve for the unknown side lengths.

By following these steps, you should be able to solve for the unknown side lengths in your triangle using the Perpendicular Bisector Theorem and the Isosceles Triangle Theorem.

To find the area, we first need to determine the points of intersection between the given lines.

The line y = 1 - 3 + 2√e simplifies to y = -2 + 2√e.

The line y = e¹ is equivalent to y = e.

To find the points of intersection, we set the two equations equal to each other:

-2 + 2√e = e.

Simplifying the equation, we get:

2√e = e + 2.

Squaring both sides, we obtain:

4e = e² + 4e + 4.

Rearranging the equation, we have:

e² = 4.

Taking the square root of both sides, we find:

e = 2 or e = -2 (ignoring the negative value).

Substituting e = 2 back into the equation y = -2 + 2√e, we get y = -2 + 2√2.

The area bounded by the given lines and curves can be calculated using integration. We integrate y = -2 + 2√2 from x = -1 to x = 0 √e - 1 to find the area. Evaluating the integral, we get:

To model the number of visitors to the museum "t" months from now, we need to account for the 4% increase in visitors each month. We start with the initial number of visitors, which is given as 3000.

To calculate the number of visitors after 1 month, we multiply the initial number of visitors (3000) by (1 + 0.04), which represents a 4% increase. This gives us 3000 * (1 + 0.04) = 3120.

0.2x = 92.7

x = 92.7/0.2

x = 463.5

Substituting the value of x back into either the supply or demand function, we find the equilibrium price:

p = 0.2(463.5) + 9 = 93

The equilibrium price is $93, and the equilibrium quantity is 463.5 units.

To calculate the producer's surplus, we need to find the area between the supply curve and the equilibrium price line up to the equilibrium quantity. This area represents the additional revenue earned by producers above their minimum supply price. Since the supply function is linear, the producer's surplus is given by the formula:

Producer's Surplus = (1/2) * (Equilibrium Quantity) * (Equilibrium Price - Minimum Supply Price)

Using the equilibrium price of $93, the minimum supply price of $9, and the equilibrium quantity of 463.5 units, we can calculate the producer's surplus:

Producer's Surplus = (1/2) * 463.5 * (93 - 9) = 20238.75

Therefore, the producer's surplus at the market equilibrium point is $20,238.75.

The box represents the interquartile range (IQR) from Q1 to Q3 (8 to 15). The line inside the box represents the median (12).

The whiskers extend from the box to the minimum value (2) and the maximum value (35), excluding the outlier.

The outlier (35) is plotted as a point outside the whiskers.

To create a box-and-whisker plot, we need to arrange the data in ascending order first:

2, 6, 8, 8, 9, 12, 13, 14, 15, 20, 35

(a) The median is the middle value of the data when it is arranged in ascending order.

In this case, we have 11 data points, so the median is the value in the middle, which is the 6th value:

Median = 12

(b) The inner quartile range (IQR) is the range between the first quartile (Q1) and the third quartile (Q3).

To find these quartiles, we need to divide the data into four equal parts.

Q1 is the median of the lower half of the data:

Lower half: 2, 6, 8, 8, 9

Median of the lower half = 8

Q3 is the median of the upper half of the data:

Upper half: 13, 14, 15, 20, 35

Median of the upper half = 15

IQR = Q3 - Q1 = 15 - 8 = 7

(c) The upper and lower fences are used to identify potential outliers. The fences are calculated using the following formulas:

Lower fence = Q1 - 1.5 × IQR

Upper fence = Q3 + 1.5 × IQR

Lower fence = 8 - 1.5 × 7 = 8 - 10.5 = -2.5

Upper fence = 15 + 1.5 × 7 = 15 + 10.5 = 25.5

(d) To identify the outlier, we need to look for any data point that falls outside the lower and upper fences. In this case, the value 35 is greater than the upper fence (25.5), so it is considered an outlier.

e) Here is the modified box plot, including the outlier and the values on the plot:

       |        |        |        |        |        |        |

  -2.5 |  2     |  6     |  8     |  12    |  15    |  20    |  25.5

       |        |        |        |        |        |        |

The box represents the interquartile range (IQR) from Q1 to Q3 (8 to 15). The line inside the box represents the median (12). The whiskers extend from the box to the minimum value (2) and the maximum value (35), excluding the outlier. The outlier (35) is plotted as a point outside the whiskers.

The solution to the given differential equation y'' = 16y with initial conditions y(0) = -3 and y'(0) = 20 is y = -3cos(4x) + 5sin(4x).

The solution is obtained by solving the second-order linear homogeneous differential equation using the characteristic equation. The characteristic equation for the given differential equation is r^2 - 16 = 0, which has roots r = ±4. The general solution of the differential equation is then given by y(x) = [tex]c1e^{(4x)} + c2e^{(-4x)}[/tex], where c1 and c2 are constants.

Using the initial conditions y(0) = -3 and y'(0) = 20, we can determine the values of c1 and c2. Plugging in the values, we get -3 = c1 + c2 and 20 = 4c1 - 4c2. Solving these equations simultaneously, we find c1 = -3/2 and c2 = 3/2.

Substituting these values back into the general solution, we obtain y(x) = (-3/2)e^(4x) + (3/2)e^(-4x). Simplifying further, we get y(x) = -3cos(4x) + 5sin(4x). Therefore, the solution to the given differential equation with the specified initial conditions is y = -3cos(4x) + 5sin(4x).

The values of θ (between 0 and 2π) where tan(θ) = 1 are π/4 and 5π/4, and the values of θ (between 0 and 2π) where tan(θ) = -1 are 3π/4 and 7π/4.

To determine the values of θ (between 0 and 2π) where tan(θ) = 1, we can use the unit circle and the properties of the tangent function.

In the unit circle, the tangent of an angle θ is defined as the ratio of the y-coordinate to the x-coordinate of the point on the unit circle corresponding to that angle.

The tangent function is positive in the first and third quadrants and negative in the second and fourth quadrants.

For tan(θ) = 1, we are looking for angles where the y-coordinate and the x-coordinate are equal. In the first quadrant, there is an angle θ = π/4 (45 degrees) where tan(θ) = 1.

In the third quadrant, the angle θ = 5π/4 (225 degrees) also satisfies tan(θ) = 1.

To determine the values of θ (between 0 and 2π) where tan(θ) = -1, we follow a similar process. In the second quadrant, there is an angle θ = 3π/4 (135 degrees) where tan(θ) = -1.

In the fourth quadrant, the angle θ = 7π/4 (315 degrees) also satisfies tan(θ) = -1.

Therefore, the values of θ (between 0 and 2π) where tan(θ) = 1 are π/4 and 5π/4, and the values of θ (between 0 and 2π) where tan(θ) = -1 are 3π/4 and 7π/4.

The volume of the solid obtained by rotating the region bounded by y = 1 - x^2, y = 0, and the x-axis from x = -1 to x = 1 is π cubic units.

To determine the volume of the solid obtained by rotating the region bounded by the curves y = 1 - x^2, y = 0, and the x-axis from x = -1 to x = 1, we can use the method of cylindrical shells.

The formula for the volume of a solid obtained by rotating a curve around the y-axis using cylindrical shells is:

V = 2π∫[a,b] x * h(x) dx,

where a and b are the limits of integration (in this case, -1 and 1), x represents the x-coordinate, and h(x) represents the height of the shell at each x.

In this case, the height of each shell is given by h(x) = 1 - x^2, and x represents the radius of the shell.

Therefore, the volume of the solid is:

V = 2π∫[-1,1] x * (1 - x^2) dx.

Let's integrate this expression to find the volume:

V = 2π ∫[-1,1] (x - x^3) dx.

Integrating term by term, we get:

V = 2π [1/2 * x^2 - 1/4 * x^4] |[-1,1]

= 2π [(1/2 * 1^2 - 1/4 * 1^4) - (1/2 * (-1)^2 - 1/4 * (-1)^4)]

= 2π [(1/2 - 1/4) - (1/2 - 1/4)]

= 2π [1/4 - (-1/4)]

= 2π * 1/2

= π.

Therefore, the volume of the solid obtained by rotating the region bounded by y = 1 - x^2, y = 0, and the x-axis from x = -1 to x = 1 is π cubic units.

4. True. When finding the derivative of a fraction, you have to use the Quotient Rule.

5. False. The derivative of f(x) = √x does not have the same domain as f(x).

4. True. When finding the derivative of a fraction, such as (f(x)/g(x)), where f(x) and g(x) are functions, you need to use the Quotient Rule. The Quotient Rule states that the derivative of a fraction is equal to (g(x) times the derivative of f(x) minus f(x) times the derivative of g(x)) divided by (g(x))^2. This rule helps handle the differentiation of the numerator and denominator separately and then combines them using appropriate operations.

5. False. The derivative of f(x) = √x is given by f'(x) = (1/2√x). The domain of f(x) is all non-negative real numbers since taking the square root of a negative number is undefined in the real number system. However, the derivative f'(x) has a restricted domain, excluding x = 0. This is because the derivative involves division by √x, which would result in division by zero at x = 0. Therefore, the domain of f'(x) is the set of positive real numbers, excluding 0.
