If f'(9) = 8 and g'(9) = 5. The value of h'(9) where h(x) = 2f(x) + 3g(x) + 6 is 31 after differentiation.

The sum rule and constant multiple rule are two fundamental rules of differentiation.

According to the sum rule, if we have a function h(x) which is the sum of two functions f(x) and g(x), then the derivative of h(x) with respect to x is equal to the sum of the derivatives of f(x) and g(x).

To find h'(9), we need to differentiate the function h(x) with respect to x and then evaluate it at x = 9.

Given that h(x) = 2f(x) + 3g(x) + 6, we can differentiate h(x) using the sum rule and constant multiple rule of differentiation:

h'(x) = 2f'(x) + 3g'(x) + 0

Since f'(9) = 8 and g'(9) = 5, we substitute these values into the equation:

h'(9) = 2f'(9) + 3g'(9) + 0

      = 2(8) + 3(5) + 0

      = 16 + 15

      = 31

Therefore, The correct answer is h'(9) = 31.

Given that sin(c) = 5x in quadrant I, we can determine the value of sin(2x), cos(22), and tan(2x) without explicitly finding the value of x.

In quadrant I, all trigonometric functions are positive. We can use the double-angle identities to find the values of sin(2x), cos(22), and tan(2x) in terms of sin(c). Using the double-angle identity for sine, sin(2x) = 2sin(x)cos(x). We can rewrite this as sin(2x) = 2(5x)cos(x) = 10x*cos(x).

For cos(22), we can use the identity cos(2θ) = 1 - 2sin²(θ). Plugging in θ = 11, we get cos(22) = 1 - 2sin²(11). Since we know sin(c) = 5x, we can substitute this value to get cos(22) = 1 - 2(5x)² = 1 - 50x². Using the double-angle identity for tangent, tan(2x) = (2tan(x))/(1 - tan²(x)). Substituting 5x for tan(x), we get tan(2x) = (2(5x))/(1 - (5x)²) = 10x/(1 - 25x²).

In conclusion, we have obtained the expressions for sin(2x), cos(22), and tan(2x) in terms of sin(c) = 5x. The values of sin(2x), cos(22), and tan(2x) can be determined by substituting the appropriate expression for x into the corresponding equation.

To express the integral of f(x, y) = x^2y over the region U, which is the region in the first quadrant above the graph of y = r^2 and below the graph of y = 3x, we need to set up a double integral.

The region U can be described by the inequalities:

0 ≤ x ≤ y/3 (from the graph y = 3x)

0 ≤ y ≤ √x (from the graph y = r^2)

The double integral of f(x, y) over the region U can be written as:

∬U x^2y dA

where dA represents the infinitesimal area element in the xy-plane.

To express this integral as a double integral, we need to specify the limits of integration for x and y.

The function f(x) = e^x^2 is not injective (one-to-one) on its natural domain because it fails the horizontal line test. This means that there exist different values of x within its domain that map to the same y-value. In other words, there are multiple x-values that produce the same output value.

To find the largest possible domain A, where all elements of A are non-negative and f(x) is defined, we need to consider the domain restrictions of the exponential function. The exponential function e^x is defined for all real numbers, but its output is always positive. Therefore, in order for f(x) = e^x^2 to be non-negative, the values of x^2 must also be non-negative. This means that the largest possible domain A is the set of all real numbers where x is greater than or equal to 0. In interval notation, this can be written as A = [0, +∞). Within this domain, all elements are non-negative, and the function f(x) is well-defined.

b. The exact value of sin(%) depends on the specific value of the angle %.

c. sin^(-1)(-0.5) = -pi/6 radians

d. cos(0) = 1.

To find the exact value of cos(105), we can use the cosine addition formula:

Cos(A + B) = cos(A)cos(B) – sin(A)sin(B)

In this case, we can write 105 as the sum of 60 and 45 degrees:

Cos(105) = cos(60 + 45)

Using the cosine addition formula:

Cos(105) = cos(60)cos(45) – sin(60)sin(45)

We know the exact values of cos(60) and sin(45) from special right triangles:

Cos(60) = ½

Sin(45) = √2/2

Substituting these values:

Cos(105) = (1/2)(√2/2) – (√3/2)(√2/2)

        = √2/4 - √6/4

        = (√2 - √6)/4

b. To find the exact value of sin(%), we need to know the specific value of the angle %. Without that information, we cannot determine the exact value.

To find dy, we need to take the derivative of f(x) with respect to x:

f(x) = x^4 - 5x^3 + 2

f'(x) = 4x^3 - 15x^2

Now, we can substitute x = 2 to find the value of dy:

f'(2) = 4(2)^3 - 15(2)^2 = 8(8) - 15(4) = 64 - 60 = 4

Therefore, dy = 4.

To find Ay, we need to use the formula for the average rate of change:

Ay = (f(Ax+h) - f(Ax))/h

where Ax = -0.2 and h is a small change in x.

Let's choose h = 0.1:

f(Ax+h) = f(-0.2 + 0.1) = f(-0.1) = (-0.1)^4 - 5(-0.1)^3 + 2 = 0.0209

f(Ax) = f(-0.2) = (-0.2)^4 - 5(-0.2)^3 + 2 = 2.096

The antiderivative of e(b) with respect to 'a' is simply e(b) multiplied by the derivative of 'a' with respect to 'a', which is 1. Therefore, the antiderivative of f(a) = e(b) is F(a) = e(b)a + C, where 'C' is the constant of integration. Now, let's move on to evaluating the definite integral I = ∫ e(2x) dx.

To evaluate this definite integral, we need to find the antiderivative of the integrand e(2x) and then apply the fundamental theorem of calculus.

Find the antiderivative:

The antiderivative of e(2x) with respect to 'x' is (1/2)e(2x). Therefore, we have F(x) = (1/2)e(2x).

Apply the fundamental theorem of calculus:  According to the fundamental theorem of calculus, the definite integral of a function f(x) from a to b is equal to the antiderivative evaluated at the upper limit (b) minus the antiderivative evaluated at the lower limit (a). In mathematical notation:

I = F(b) - F(a)

Applying this to our integral, we have:

I = F(x)| from 0 to 2

Substituting the antiderivative F(x) = (1/2)e(2x), we get:

I=[(1/2)e(2x)]| from 0 to 2

Evaluate the upper limit:

Iupper=[(1/2)e(2∗2)]=[(1/2)e4]

Evaluate the lower limit:

The integral for the length of the curve: L = ∫[0,4] √(1 + (12x + 14)^2) dx

Step-by-step explanation:

To find the length of the curve defined by the equation y = 6x^2 + 14x from the point (0, 0) to the point (4, 152), we can use the arc length formula for a curve y = f(x):

L = ∫[a,b] √(1 + (f'(x))^2) dx

In this case, the function is y = 6x^2 + 14x, so we need to find f'(x) first:

f'(x) = d/dx (6x^2 + 14x)

The derivatives of the given functions with respect to x are as follows:

1. y' = 9x^2

2. y' = -6x^2

3. y' = 12x^4 ln(x^3) + 6x^3 (2x^2 + 1)

4. y' = -3x^2 ln(x^a) - ax^(a-1)

Step-by-step explanation:

1. For the function y = 3x^3, we can apply the power rule of differentiation, which states that the derivative of x^n is n*x^(n-1). Thus, taking the derivative with respect to x, we have y' = 3 * 3x^2 = 9x^2.

2. For the function y = -2x^3 + 1, the derivative of a constant (1 in this case) is zero, and the derivative of -2x^3 using the power rule is -6x^2. Therefore, the derivative of y is y' = -6x^2.

3. For the function y = ln(x^3)(2x^2 + 1), we can apply the product rule and the chain rule. The derivative of ln(x^3) is (1/x^3) * 3x^2 = 3/x. The derivative of (2x^2 + 1) is 4x. Applying the product rule, we get y' = 3/x * (2x^2 + 1) + ln(x^3) * 4x = 12x^4 ln(x^3) + 6x^3 (2x^2 + 1).

4. For the function y = (-x^3 - 3) ln(x^a), we need to use both the chain rule and the product rule. The derivative of (-x^3 - 3) is -3x^2, and the derivative of ln(x^a) is (1/x^a) * ax^(a-1) = a/x. Applying the product rule, we have y' = (-3x^2) * ln(x^a) + (-x^3 - 3) * a/x = -3x^2 ln(x^a) - ax^(a-1).

To compute the derivative of the given functions, we apply differentiation rules and techniques.

a. For f(x) = x + 3ex - sin(x), we differentiate each term separately. The derivative of x with respect to x is 1. The derivative of 3ex with respect to x is 3ex. The derivative of sin(x) with respect to x is -cos(x). Therefore, the derivative of f(x) is 1 + 3ex - cos(x).

b. For f(x) = sin(x² + 5) + ln(x² + 5), we use the chain rule and derivative of the natural logarithm. The derivative of sin(x² + 5) with respect to x is cos(x² + 5) times the derivative of the inner function, which is 2x. The derivative of ln(x² + 5) with respect to x is (2x / (x² + 5)). Therefore, the derivative of f(x) is 2xcos(x² + 5) + (2x / (x² + 5)).

c. For f(x) = asin(x) + atan(2x), we use the derivative of the inverse trigonometric functions. The derivative of asin(x) with respect to x is 1 / √(1 - x²) using the derivative formula of arcsine. The derivative of atan(2x) with respect to x is 2 / (1 + 4x²) using the derivative formula of arctangent. Therefore, the derivative of f(x) is 1 / √(1 - x²) + 2 / (1 + 4x²).

By applying the differentiation rules and formulas, we can find the derivatives of the given functions.

The solution is (5 + °) ((2 + 3t²)² / 12) + C for the indefinite integral.

A key idea in calculus is an indefinite integral, commonly referred to as an antiderivative. It symbolises a group of functions that, when distinguished, produce a certain function. The integral symbol () is used to represent the indefinite integral of a function, and it is usually followed by the constant of integration (C). By using integration techniques and principles, it is possible to find an endless integral by turning the differentiation process on its head.

The expression for the indefinite integral with the terms 2 5+°, ( ) 3t?, 2 + 3t 2, and dt is given by;[tex]∫ 2(5 + °) (3t² + 2) / (2 + 3t²) dt[/tex]

To solve the above indefinite integral, we shall use the substitution method as shown below:

Let y = 2 + [tex]3t^2[/tex] Then dy/dt = 6t, from this, we can find dt = dy / 6t

Substituting y and dt in the original expression, we have∫ (5 + °) (3t² + 2) / (2 + 3t²) dt= ∫ (5 + °) (1/6) (6t / (2 + 3t²)) (3t² + 2) dt= ∫ (5 + °) (1/6) (y-1) dy

Integrating the expression with respect to y we get,(5 + °) (1/6) * [y² / 2] + C = (5 + °) (y² / 12) + C

Substituting y = 2 +[tex]3t^2[/tex] back into the expression, we have(5 + °) ((2 + 3t²)² / 12) + C

The probabilities as follows:

A. P(F2|F1) = 0.3 (30%)

B. P(F1|F2) = 0.25 (25%)

C. P(F1 or F2) = 0.19 (19%)

D. P(not F1 and not F2) = 0.81 (81%)

To solve this problem, we can use the concept of conditional probability and the principle of inclusion-exclusion.

Given:

P(F1) = 0.10 (Probability of failing at Check Point 1)

P(F2) = 0.12 (Probability of failing at Check Point 2)

P(F1 and F2) = 0.03 (Probability of failing at both Check Point 1 and Check Point 2)

A. To find the probability that an item failed at Check Point 1 and also failed at Check Point 2 (F2|F1), we use the formula for conditional probability:

P(F2|F1) = P(F1 and F2) / P(F1)

Substituting the given values:

P(F2|F1) = 0.03 / 0.10

P(F2|F1) = 0.3

Therefore, the probability that an item failed at Check Point 1 and also failed at Check Point 2 is 0.3 or 30%.

B. To find the probability that an item failed at Check Point 2 given that it failed at Check Point 1 (F1|F2), we use the same formula:

P(F1|F2) = P(F1 and F2) / P(F2)

Substituting the given values:

P(F1|F2) = 0.03 / 0.12

P(F1|F2) = 0.25

Therefore, the probability that an item failed at Check Point 2 and also failed at Check Point 1 is 0.25 or 25%.

C. To find the probability that an item failed at either Check Point 1 or Check Point 2 (F1 or F2), we can use the principle of inclusion-exclusion:

P(F1 or F2) = P(F1) + P(F2) - P(F1 and F2)

Substituting the given values:

P(F1 or F2) =[tex]0.10 + 0.12 - 0.03[/tex]

P(F1 or F2) = 0.19

Therefore, the probability that an item failed at either Check Point 1 or Check Point 2 is 0.19 or 19%.

D. To find the probability that an item failed at neither of the check points (not F1 and not F2), we can subtract the probability of failing from 1:

P(not F1 and not F2) = 1 - P(F1 or F2)

Substituting the previously calculated value:

P(not F1 and not F2) = 1 - 0.19

P(not F1 and not F2) = 0.81

Therefore, the probability that an item failed at neither Check Point 1 nor Check Point 2 is 0.81 or 81%.

In conclusion, we have calculated the probabilities as follows:

A. P(F2|F1) = 0.3 (30%)

B. P(F1|F2) = 0.25 (25%)

C. P(F1 or F2) = 0.19 (19%)

D. P(not F1 and not F2) = 0.81 (81%)

a. The derivative of D(p) with respect to p is -10

b.  The value of p when D'(p) = -10 is 1

c. The corresponding quantity x is 110

d. The equation for elasticity is E(p) = -11.

To find the equation for elasticity, we need to calculate the derivative of the demand function, D(p), with respect to p. Let's go through the steps:

D(p) = 120 - 10p

a) Find the derivative of D(p) with respect to p:

D'(p) = -10

b) Find the value of p when D'(p) = -10:

D'(p) = -10

-10 = -10p

p = 1

c) Plug the value of p into the demand function D(p) to find the corresponding quantity x:

D(p) = 120 - 10p

D(1) = 120 - 10(1)

D(1) = 110

So, when the price is $1, the quantity demanded is 110.

d) Substitute the values of D(1), D'(1), and p = 1 into the elasticity equation:

E(p) = D(p) * p / D'(p)

E(1) = D(1) * 1 / D'(1)

E(1) = 110 * 1 / -10

E(1) = -11

Therefore, the equation for elasticity is E(p) = -11.

To find the first four terms of the piecewise function, we substitute the values of n = 3, 4, 5, and 6 into the function and evaluate the corresponding terms.

For n = 3, since n is less than 5, we use the expression 2n + 1:

a3 = 2(3) + 1 = 7.

For n = 4, since n is less than 5, we use the expression 2n + 1:

a4 = 2(4) + 1 = 9.

For n = 5, the function does not specify an expression. In this case, we assume a constant value of 1:

a5 = 1.

For n = 6, since n is greater than 5, we use the expression n^2 - 5:

a6 = 6^2 - 5 = 31.

Therefore, the first four terms of the piecewise function are a3 = 7, a4 = 9, a5 = 1, and a6 = 31.

The particular solution y = f(x) that satisfies the given differential equation and initial condition is f(x) = x - 8/x + 8.

To find the particular solution, we first integrate the given expression for f'(x) concerning x. The antiderivative of (x^2 - 8)/x^2 can be found by decomposing it into partial fractions:

(x^2 - 8)/x^2 = (1 - 8/x^2)

Integrating both sides, we have:

∫f'(x) dx = ∫[(1 - 8/x^2) dx]

Integrating the right side, we get:

f(x) = x - 8/x + C

To determine the value of the constant C, we use the initial condition f(1) = 7. Substituting x = 1 and f(x) = 7 into the equation, we have:

7 = 1 - 8/1 + C

Simplifying further, we find:

C = 8

Therefore, the particular solution that satisfies the given differential equation and initial condition is:

f(x) = x - 8/x + 8.

This solution meets the requirements of the differential equation and the given initial condition.

Question 1: The exact function value of [tex]$\sec^{-1}\left(-\frac{1}{2}\right)$[/tex] is [tex]$\frac{2\pi}{3}$[/tex].

Question 2: The solution to the equation [tex]$e^{2x} + e^x - 2 = 0$[/tex] is [tex]$x = 0$[/tex].

Question 4: The slope of the c at point Q on the curve [tex]$y = \cos(Tx)$[/tex] is [tex]$-T\sin(Tx)$[/tex].

Question 1:

To find the exact function value of [tex]$\sec^{-1}\left(-\frac{1}{2}\right)$[/tex], we need to determine the angle whose secant is equal to [tex]$-\frac{1}{2}$[/tex].

The secant function is defined as the reciprocal of the cosine function. So, we are looking for an angle whose cosine is equal to [tex]$-\frac{1}{2}$[/tex]. From the unit circle or trigonometric identities, we know that the cosine function is negative in the second and third quadrants.

In the second quadrant, the reference angle with a cosine of [tex]$\frac{1}{2}$[/tex] is [tex]$\frac{\pi}{3}$[/tex]. However, since we want the cosine to be negative, the angle becomes [tex]$\pi - \frac{\pi}{3} = \frac{2\pi}{3}$[/tex].

Therefore, the exact function value is [tex]$\sec^{-1}\left(-\frac{1}{2}\right) = \frac{2\pi}{3}$[/tex].

Question 2:

To solve the equation [tex]$e^{2x} + e^x - 2 = 0$[/tex] for x, we can rewrite it as a quadratic equation.

Let [tex]$u = e^x$[/tex]. The equation becomes [tex]$u^2 + u - 2 = 0$[/tex]. This equation can be factored as [tex]$(u - 1)(u + 2) = 0$[/tex].

Setting each factor equal to zero, we have u - 1 = 0 or u + 2 = 0.

For u - 1 = 0, we get u = 1. Substituting back [tex]u = e^x[/tex], we have [tex]$e^x = 1$[/tex]. Taking the natural logarithm of both sides, we get [tex]$x = \ln(1) = 0$[/tex].

For u + 2 = 0, we get u = -2. Substituting back [tex]$u = e^x$[/tex], we have [tex]$e^x = -2$[/tex], which has no real solutions since the exponential function is always positive.

Therefore, the solution to the equation [tex]$e^{2x} + e^x - 2 = 0$[/tex] is x = 0.

Question 4:

Given the curve [tex]$y = \cos(Tx)$[/tex], where P(0.5, 0) lies on the curve, and we want to find the slope of the tangent line at the point [tex]Q(x, \cos(7x))[/tex].

The slope of a tangent line can be found by taking the derivative of the function and evaluating it at the given point.

Taking the derivative of [tex]$y = \cos(Tx)$[/tex] with respect to x, we have [tex]$\frac{dy}{dx} = -T\sin(Tx)$[/tex].

To find the slope at point Q, we substitute x with the x-coordinate of point Q, which is x, and evaluate the derivative:

Slope at point [tex]Q = $\frac{dy}{dx}\bigg|_{x = x} = -T\sin(Tx)\bigg|_{x = x} = -T\sin(Tx)$.[/tex]

Therefore, the slope of the tangent line at point Q is [tex]$-T\sin(Tx)$[/tex].
