The given equation represents the Fundamental Theorem of Calculus, which provides a fundamental connection between the definite integral and the antiderivative of a function.

The given expression represents the equation of the Fundamental Theorem of Calculus, stating that the definite integral of a function f(x) with respect to x over the interval [a, b] is equal to the antiderivative of f(x) evaluated at b minus the antiderivative of f(x) evaluated at a. This theorem allows us to calculate definite integrals by evaluating the antiderivative of the integrand function at the endpoints. The Fundamental Theorem of Calculus relates the definite integral of a function to its antiderivative. The equation can be written as:

∫[a, b] f(x) dx = F(b) - F(a)

where F(x) is the antiderivative (or indefinite integral) of f(x).

The left-hand side of the equation represents the definite integral of f(x) with respect to x over the interval [a, b]. It calculates the net area under the curve of the function f(x) between the x-values a and b. The right-hand side of the equation involves evaluating the antiderivative of f(x) at the endpoints b and a, respectively. This is done by finding the antiderivative of f(x) and plugging in the values b and a. Subtracting the value of F(a) from F(b) gives us the net change in the antiderivative over the interval [a, b]. The equation essentially states that the net change in the antiderivative of f(x) over the interval [a, b] is equal to the area under the curve of f(x) over that same interval.

It is given that Ay+ 6x +Bz =D is an equation of the tangent plane to the given surface at (1.1.1). The value of A+B+D is 22.

To find the equation of the tangent plane, we need to find the partial derivatives of the given surface at (1,1,1).

∂/∂x (3x^2 + 3xyz - y^2) = 6x + 3yz

∂/∂y (3x^2 + 3xyz - y^2) = -2y + 3xz

∂/∂z (3x^2 + 3xyz - y^2) = 3xy

Plugging in the values for x=1, y=1, z=1, we get:

∂/∂x = 9

∂/∂y = 1

∂/∂z = 3

So the equation of the tangent plane is:

9(y-1) + (z-1) + 3(x-1) = 0

Simplifying, we get:

Ay + 6x + Bz = D, where A = 9, B = 1, D = 12

Therefore, A + B + D = 9 + 1 + 12 = 22.

To evaluate c'(2), we need to use the chain rule.

The chain rule states that if c(x) = f(g(x)), then the derivative of c(x) with respect to x, denoted as c'(x), is given by c'(x) = f'(g(x)) * g'(x).

From the given table, we can see the values of f(x), g(x), f'(x), and g'(x) for different values of x. We need to find the values at x = 2 to evaluate c'(2).

Let's denote f(x) = f, g(x) = g, f'(x) = f', and g'(x) = g' for simplicity.

From the table:

f(2) = -1

g(2) = 0

f'(2) = -4

g'(2) = 2

Now, we can evaluate c'(2) using the chain rule:

c'(2) = f'(g(2)) * g'(2)

     = f'(0) * 2

From the table, we don't have the value of f'(0) directly, but we can find it using the values of f'(x) and g(x) from the table.

Since g(2) = 0, we can find the corresponding value of x from the table, which is x = 4. Therefore, f'(0) = f'(4).

From the table:

f(4) = -4

g(4) = -2

f'(4) = 3

g'(4) = 1

Now we have the value of f'(0) = f'(4) = 3.

Substituting this into the expression for c'(2):

c'(2) = f'(g(2)) * g'(2)

     = f'(0) * 2

     = 3 * 2

     = 6

Therefore, c'(2) = 6.

The smallest value of n for which the graphs of u = sin(z) and u' = ne^a are tangent is n = 1/sqrt(2).

To find the smallest value of n for which the graphs of u = sin(z) and u' = ne^a intersect and are tangent, we need to find the value of n that satisfies the conditions of intersection and tangency. The equation u' = ne^a represents the derivative of u with respect to z, which gives us the slope of the tangent line to the graph of u = sin(z) at any given point.

Intersection: For the graphs to intersect, the values of u (sin(z)) and u' (ne^a) must be equal at some point. Therefore, we have the equation sin(z) = ne^a. Tangency: For the graphs to be tangent, the slopes of the two curves at the point of intersection must be equal. In other words, the derivative of sin(z) and u' (ne^a) evaluated at the point of intersection must be equal. Therefore, we have the equation cos(z) = ne^a.

We can solve these two equations simultaneously to find the value of n and a that satisfy both conditions. From sin(z) = ne^a, we can isolate z by taking the inverse sine: z = arcsin(ne^a). Substituting this value of z into cos(z) = ne^a, we have: cos(arcsin(ne^a)) = ne^a. Using the trigonometric identity cos(arcsin(x)) = √(1 - x^2), we can rewrite the equation as: √(1 - (ne^a)^2) = ne^a. Squaring both sides, we get: 1 - n^2e^2a = n^2e^2a. Rearranging the equation, we have: 2n^2e^2a = 1. Simplifying further, we find: n^2e^2a = 1/2. Taking the natural logarithm of both sides, we get: 2a + 2ln(n) = ln(1/2). Solving for a, we have: a = (ln(1/2) - 2ln(n))/2

To find the smallest value of n for which the graphs are tangent, we need to minimize the value of a. Since a > 0, the smallest value of a occurs when ln(1/2) - 2ln(n) = 0. Simplifying this equation, we get: ln(1/2) = 2ln(n). Dividing both sides by 2, we have: ln(1/2) / 2 = ln(n). Using the property of logarithms, we can rewrite the equation as: ln(sqrt(1/2)) = ln(n). Taking the exponential of both sides, we find: sqrt(1/2) = n. Simplifying the square root, we obtain: 1/sqrt(2) = n. Therefore, the smallest value of n for which the graphs of u = sin(z) and u' = ne^a are tangent is n = 1/sqrt(2).

Based on the information provided, the second-order differential equation is given as:

y'' - y' = 0

To find a solution of the second-order initial value problem (IVP), we need to determine the specific values of the parameters that satisfy the initial conditions.

The given initial conditions are:

y(-1) = 0

y'(-1) = -6

Let's start by finding the general solution to the differential equation. The characteristic equation is:

r^2 - r = 0

Factoring out an r:

r(r - 1) = 0

This gives us two possible roots: r = 0 and r = 1.

Therefore, the general solution is of the form:

y = c1 * e^0 + c2 * e^x

y = c1 + c2 * e^x

To find the specific solution that satisfies the initial conditions, we substitute the values of x and y into the general solution:

y(-1) = c1 + c2 * e^(-1) = 0          (equation 1)

y'(-1) = c2 * e^(-1) = -6              (equation 2)

From equation 2, we can solve for c2:

c2 = -6 * e

Substituting this value of c2 into equation 1:

c1 + (-6 * e) * e^(-1) = 0

c1 - 6 = 0

c1 = 6

Therefore, the specific solution to the IVP is:

y = 6 - 6e^x

This is the solution that satisfies the second-order differential equation y'' - y' = 0 with the given initial conditions y(-1) = 0 and y'(-1) = -6.

If the population continues to grow at a rate of 3% per year, it will be approximately 195 people in ten years. It takes approximately 24 years for the population to at least double if the growth rate remains constant.

Explanation: The formula for exponential growth can be expressed as P(t) = P0 * [tex](1+r)^{t}[/tex], where P(t) represents the population at time t, P0 is the initial population, r is the growth rate per time period, and t is the number of time periods. In this case, the initial population P0 is 150, and the growth rate r is 3% or 0.03. Therefore, the formula for the population as a function of time is P(t) = 150 *[tex](1 + 0.03)^{t}.[/tex]

To find the population in ten years, we substitute t = 10 into the formula: P(10) = 150 * [tex](1 + 0.03)^{10}[/tex]. Evaluating this expression gives us P(10) ≈ 195. Thus, if the population continues to grow at a rate of 3% per year, it will be approximately 195 people in ten years.

To determine the number of full years it takes to at least double the population, we need to find the value of t when P(t) = 2 * P0. In this case, P0 is 150. So, we set up the equation 2 * 150 = 150 * [tex](1 + 0.03)^{t}[/tex] and solve for t. Simplifying the equation, we get 2 = [tex](1 + 0.03)^{t}[/tex]. Taking the natural logarithm of both sides, we have ln(2) = t * ln(1 + 0.03). Dividing both sides by ln(1 + 0.03), we find t ≈ ln(2) / ln(1.03) ≈ 23.45.

The correct polar pairs that could represent (3, 120°) are:

B. (3, -240)

C. (-3, 240)

E. (3, -60°)

The polar pair (3, 120°) can be represented by the polar pairs (3, -240), (-3, 240), and (3, -60°).

To convert from polar coordinates (r, θ) to rectangular coordinates (x, y), we use the following formulas:

x = r * cos(θ)

y = r * sin(θ)

Given the polar coordinates (3, 120°), we can calculate the rectangular coordinates as follows:

x = 3 * cos(120°) ≈ -1.5

y = 3 * sin(120°) ≈ 2.598

So, the rectangular coordinates are approximately (-1.5, 2.598). Now, let's convert these rectangular coordinates back to polar coordinates:

r = sqrt(x^2 + y^2) ≈ sqrt((-1.5)^2 + 2.598^2) ≈ 3

θ = arctan(y/x) ≈ arctan(2.598/(-1.5)) ≈ -60°

Therefore, the polar representation of the rectangular coordinates (-1.5, 2.598) is approximately (3, -60°). Comparing this with the given options, we can see that options B, C, and E match the polar representation (3, 120°).

We know the angles A and B and the length of side a we found the lengths of sides b = 10.79 cm and c = 6.46 cm :

Start by drawing a line segment of length 7.5 cm as side a.

At one end of side a, draw an angle of 43°, which is angle A.

At the other end of side a, draw an angle of 101°, which is angle B. Make sure the angle is wide enough to intersect with the other side.

The intersection of the two angles will be point C, completing the triangle.

To find the lengths of sides b and c, you can use the law of sines. The law of sines states that the ratio of the length of a side to the sine of its opposite angle is the same for all sides of a triangle.

Using the law of sines: b / sin(B) = a / sin(A)

b / sin(101°) = 7.5 cm / sin(43°)

Now, you can solve for b: b = sin(101°) * (7.5 cm / sin(43°))

b = 10.79 cm

Similarly, you can find c using the law of sines: c / sin(C) = a / sin(A)

c / sin(180° - A - B) = 7.5 cm / sin(43°)

(a) To find a vector parametric equation r(t) for the line segment C, we can use the points P and Q as the initial and final points of the parametrization.

Let's consider the position vector r(t) = (x(t), y(t)). Since the line segment starts at point P = (0, -2) when t = 0, and ends at point Q = (4, 2) when t = 1, we can set up the following equations:

When t = 0:

r(0) = (x(0), y(0)) = (0, -2)

When t = 1:

r(1) = (x(1), y(1)) = (4, 2)

To obtain the vector parametric equation, we can express x(t) and y(t) separately:

x(t) = 4t

y(t) = -2 + 4t

Therefore, the vector parametric equation for the line segment C is:

r(t) = (4t, -2 + 4t)

(b) Using the vector parametric equation r(t), we can find the line integral of F along C.

The line integral of F along C is given by:

∫[C] F · dr = ∫[a to b] F(r(t)) · r'(t) dt

In this case, [tex]F(x, y) = r^2i + y^2j, so F(r(t)) = (4t)^2i + (-2 + 4t)^2j.[/tex]

The derivative of r(t) with respect to t is r'(t) = (4, 4).

Substituting these values, we have:

[tex]\int\ [C] F dr = \int\limits^a_b (16t^2i + (-2 + 4t)^2j) (4, 4) dt\\= \int\limits^a_b (64t^2 + (-2 + 4t)^2) dt[/tex]

(c) To evaluate the line integral, we need to substitute the limits of integration (a and b) into the integral expression and evaluate it.

Given that a = 0 and b = 1, we can evaluate the line integral:

[tex]\int\ [C] F dr = \int\limits^0_1(64t^2 + (-2 + 4t)^2) dt[/tex]

Simplifying the integral expression and evaluating it, we find the result of the line integral along C.

[tex](64t^2 + (-2 + 4t)^2) = 64t^2 + (4t - 2)^2\\= 64t^2 + (16t^2 - 16t + 4)\\= 80t^2 - 16t + 4[/tex]

Now, we can integrate this expression:

[tex]\int\limits^0_1(80t^2 - 16t + 4) dt\\= [80 * (1/3)t^3 - 8t^2 + 4t] evaluated from 0 to 1\\= (80 * (1/3)(1)^3 - 8(1)^2 + 4(1)) - (80 * (1/3)(0)^3 - 8(0)^2 + 4(0))\\= (80/3 - 8 + 4) - (0)\\= 80/3 - 4[/tex]

f(1) represents the value of the function f(x) at x = 1. In this case, f(1) = 3, which means that when x is 1, the value of the function is 3.

What is Derivative?

In mathematics, the derivative is a way of showing the rate of change: that is, the amount by which a function changes at one given point. For functions that act on real numbers, it is the slope of the tangent line at a point on the graph.

To find the derivative of the function f(x) = 6x / (x² + 1), we can use the quotient rule. The quotient rule states that if we have a function u(x) = g(x) / h(x), then the derivative of u(x) with respect to x is given by:

u'(x) = (g'(x)h(x) - g(x)h'(x)) / (h(x))²

In this case, g(x) = 6x and h(x) = x² + 1. Let's differentiate g(x) and h(x) to apply the quotient rule:

g'(x) = 6

h'(x) = 2x

Now we can apply the quotient rule:

f'(x) = (g'(x)h(x) - g(x)h'(x)) / (h(x))²

= (6(x² + 1) - 6x(2x)) / (x² + 1)²

= (6x² + 6 - 12x²) / (x² + 1)²

= (-6x² + 6) / (x² + 1)²

Now, let's evaluate f(1) and f'(1):

To find f(1), we substitute x = 1 into the original function:

f(1) = 6(1) / (1² + 1)

= 6 / 2

= 3

To find f'(1), we substitute x = 1 into the derivative we just found:

f'(1) = (-6(1)² + 6) / (1² + 1)²

= 0 / 4

= 0

Interpretation:

f(1) represents the value of the function f(x) at x = 1. In this case, f(1) = 3, which means that when x is 1, the value of the function is 3.

f'(1) represents the instantaneous rate of change of the function f(x) at x = 1. In this case, f'(1) = 0, which means that at x = 1, the function has a horizontal tangent, and its rate of change is zero at that point. This indicates a possible extremum or a point of inflection.

Overall, f(1) represents the value of the function at a specific point, while f'(1) represents the rate of change of the function at that point.

To find the circulation of vector field F around the circle of radius 3 with center (5, 6), we need to evaluate the line integral of F along the circle. Answer : ∫[0, 2π] (3a * e^(3a(6+3sin(t))+159)) * (-3sin(t), 3cos(t)) dt

First, let's find the gradient of p, denoted as ∇p.

Given that p(x, y) = e^(3ay+159), we can find ∇p as follows:

∂p/∂x = 0  (since there is no x in the expression)

∂p/∂y = 3a * e^(3ay+159)

So, ∇p = (0, 3a * e^(3ay+159)).

Next, let's parameterize the circle of radius 3 centered at (5, 6). We can use polar coordinates:

x = 5 + 3 * cos(t)

y = 6 + 3 * sin(t)

where t varies from 0 to 2π to cover the entire circle.

Now, the circulation of F around the circle can be calculated as the line integral:

Circulation = ∮ F · dr

where dr is the differential arc length along the circle parameterized by t.

Since F is the gradient of p, we have F = ∇p.

So, the circulation simplifies to:

Circulation = ∮ ∇p · dr

Now, let's calculate the line integral:

Circulation = ∮ ∇p · dr

           = ∮ (0, 3a * e^(3ay+159)) · (dx, dy)

           = ∫[0, 2π] (3a * e^(3ay+159)) * (dx/dt, dy/dt) dt

Substituting the parameterization of the circle into the integral, we get:

Circulation = ∫[0, 2π] (3a * e^(3a(6+3sin(t))+159)) * (-3sin(t), 3cos(t)) dt

Now, you can evaluate this integral to find the circulation of F around the circle of radius 3 centered at (5, 6).

By integrating the supplied velocity function throughout the range [0, 0.5], the displacement can be calculated. Now let's figure out the displacement:

∫(6400t^2 - 6505t + 2686) dt

When we combine each term independently, we obtain:

[tex](6400/3)t3 - (6505/2)t2 + 2686t = (6400t2) dt - (6505t) dt + (2686t)[/tex]

Moving at time[tex]t = 0.5: (6400/3)(0.5)^3 - (6505/2)(0.5)^2 + 2686(0.5)[/tex]

Displacement at time zero: (6505/2)(0) + 2686(0) - (6400/3)(0)

The object's maximum velocity is approximately 1.32 cm/s, and it occurs at around t ≈ 1.57 seconds.

To find the object's maximum velocity, we need to determine the derivative of the height function h(t) with respect to time, which represents the rate of change of height over time. The derivative of h(t) is given by:

h'(t) = d/dt [-sin(2t) + t²]

Using the chain rule and power rule, we can simplify the derivative:

h'(t) = -2cos(2t) + 2t

To find the maximum velocity, we need to find the critical points of the derivative. Setting h'(t) = 0, we have:

-2cos(2t) + 2t = 0

Solving this equation is not straightforward, but we can approximate the value using numerical methods. In this case, the maximum velocity occurs at t ≈ 1.57 seconds, and the corresponding velocity is approximately 1.32 cm/s.

Note: The exact solution would require more precise numerical methods or algebraic manipulation, but the approximation provided is sufficient for practical purposes.

g(7x) = g(x) + C for all x in (0, [infinity]). If g(x) = ∫dt 13 x € (0, [infinity]), then we can rewrite the integral as:

g(x) = ∫dt 13 x € (0, [infinity])
g(x) = ∫dt 13 x € (0, 7x) + ∫dt 13 x € (7x, [infinity])
g(x) = ∫dt 13 x € (0, 7x) + g(7x)

Now, if we substitute 7x for x in the original equation for g(x), we get:

g(7x) = ∫dt 13 7x € (0, [infinity])

We can rewrite this integral as:

g(7x) = ∫dt 13 7x € (0, 7x) + ∫dt 13 7x € (7x, [infinity])

We can simplify the first integral using a change of variable, u = t/7, dt = 7du, which gives:

g(7x) = ∫7du 13 x € (0, x) + ∫dt 13 7x € (7x, [infinity])

We can simplify the first integral further:

g(7x) = 7∫du 13 x € (0, x) + ∫dt 13 7x € (7x, [infinity])

We can now substitute g(x) + C for the second integral:

g(7x) = 7∫du 13 x € (0, x) + g(x) + C

Finally, we can simplify the first integral using a change of variable, v = u/7, du = 7dv, which gives:

g(7x) = ∫7dv 13 x/7 € (0, x/7) + g(x) + C

g(7x) = g(x/7) + g(x) + C

Therefore, g(7x) = g(x) + C for all x in (0, [infinity]).

The faster cyclist's speed is 46 km/hr and the slower cyclist's speed is 36 km/hr.

Let the speed of the faster cyclist be x km/hr. Then the speed of the slower cyclist is x-10 km/hr.
As they are travelling towards each other, their relative speed will be the sum of their speeds. So,
Relative speed = x + (x-10) = 2x - 10 km/hr
Time taken to meet = 5 hours
Distance travelled = relative speed x time taken
210 = (2x-10) x 5
Solving for x, we get x = 46 km/hr (approx.)
Therefore, the faster cyclist's speed is 46 km/hr and the slower cyclist's speed is 36 km/hr.

To solve this problem, we need to use the formula Distance = Speed x Time. Since the two cyclists are travelling towards each other, we need to find their relative speed by adding their speeds. Then we can use the distance and time given to calculate their speeds individually using the formula Speed = Distance / Time.

The given differential equation dy = x²(2y — 3)² with the initial condition y(0) = -1, we need to follow these steps:
Step 1: Separate variables.
Divide both sides by (2y - 3)² to get dy/(2y - 3)² = x²dx.
Step 2: Integrate both sides.
∫(1/(2y - 3)²)dy = ∫x²dx + C
Step 3: Solve for y.
Let u = 2y - 3, then du = 2dy. Substitute and integrate:
(-1/2)∫(1/u²)du = (1/3)x³ + C
-1/(2u) = (1/3)x³ + C
Step 4: Apply the initial condition y(0) = -1.
-1/(2(-1)) = (1/3)(0)³ + C
C = 1/2
Step 5: Substitute back and solve for y.
-1/(2(2y - 3)) = (1/3)x³ + 1/2
2y - 3 = -6/(x³ + 3)
2y = (-6/(x³ + 3)) + 3

$5,900.00 was invested at 12% and the remaining amount ($9500 - $5,900.00 = $3,500.00) was invested at 9%.

Let's assume that the amount invested at 12% is x dollars. Since the total investment is $9500, the amount invested at 9% would be ($9500 - x) dollars. The total yield for the year is given as $1032.00.

To calculate the yield from the investment at 12%, we multiply the amount invested at 12% (x) by the interest rate of 12% (0.12): 0.12x. Similarly, the yield from the investment at 9% can be calculated by multiplying the amount invested at 9% ($9500 - x) by the interest rate of 9% (0.09): 0.09($9500 - x).

The total yield is the sum of the yields from the two investments, which is given as $1032.00. Therefore, we can write the equation: 0.12x + 0.09($9500 - x) = $1032.00.

Simplifying the equation, we have: 0.12x + 0.09($9500) - 0.09x = $1032.00.

0.03x + 0.09($9500) = $1032.00.

0.03x + $855.00 = $1032.00.

0.03x = $1032.00 - $855.00.

0.03x = $177.00.

x = $177.00 / 0.03.

x ≈ $5,900.00.

Therefore, approximately $5,900.00 was invested at 12% and the remaining amount ($9500 - $5,900.00 = $3,500.00) was invested at 9%.
