Answer:

$81.15

Step-by-step explanation:

So to find the total amount of money, you take the original price and add the sales tax.

We need to find the sales tax first, which is telling us to multiply the original price by 0.065.. so lets do that

(79.95)(0.065) = 5.19675

Since we got that answer there, we add that to the original price

$79.95 + $5.19675 = $81.14675

Which rounds to $81.15

The definite integral for the area of the surface generated by revolving the curve y = 6x^3 + 2x about the x-axis, over the interval 1 ≤ x ≤ 2, can be set up and evaluated as follows:

∫[1 to 2] 2πy √(1 + (dy/dx)^2) dx

To calculate dy/dx, we differentiate the given equation:

dy/dx = 18x^2 + 2

Substituting this back into the integral, we have:

∫[1 to 2] 2π(6x^3 + 2x) √(1 + (18x^2 + 2)^2) dx

Evaluating this definite integral will provide the surface area generated by revolving the curve about the x-axis.

b) The definite integral for the area of the surface generated by revolving the curve x = 4y - 1 about the y-axis, over the interval 1 ≤ y ≤ 4, can be set up and evaluated as follows:

∫[1 to 4] 2πx √(1 + (dx/dy)^2) dy

To calculate dx/dy, we differentiate the given equation:

dx/dy = 4

Substituting this back into the integral, we have:

∫[1 to 4] 2π(4y - 1) √(1 + 4^2) dy

Evaluating this definite integral will provide the surface area generated by revolving the curve about the y-axis.

By setting up and evaluating the definite integrals for the given curves, we can find the surface areas generated by revolving them about the respective axes. The integration process involves finding the appropriate differentials and applying the fundamental principles of calculus.

Answer:

False. The derivative of the function f(x) = 5sin(x) + cos(x) is not equal to -5cos(x) - sin(x). The correct derivative of f(x) can be obtained by applying the rules of differentiation.

To find the derivative, we differentiate each term separately. The derivative of 5sin(x) is obtained using the chain rule, which states that the derivative of sin(u) is cos(u) multiplied by the derivative of u. In this case, u = x, so the derivative of 5sin(x) is 5cos(x).

Similarly, the derivative of cos(x) is obtained as -sin(x) using the chain rule.

Therefore, the derivative of f(x) = 5sin(x) + cos(x) is:

f'(x) = 5cos(x) - sin(x).

This result shows that the derivative of f(x) is not equal to -5cos(x) - sin(x).

In summary, the statement that f'(x) = -5cos(x) - sin(x) is false. The correct derivative of f(x) = 5sin(x) + cos(x) is f'(x) = 5cos(x) - sin(x).

Answer:

5^9

Step-by-step explanation:

125=5*5*5

125^3=125*125*125

125*125*125=3*(5*5*5)

the answer 5^9

The number as a power of 5 which is obtained by the number 125^3 using the power rule and simplifying is 5⁹.

The power rule states that, when the term is raised with a power which is again raised by another power, then this can be simply written as one power by multiplying both the power.

It has to write the number 125³ as a power of 5. Let the resultant number as a power of 5 is n. Thus,

\(n=125^3\)

Rewrite the number with multiples of 125.

\(n=(5\times5\times5)^3\\n=(5^3)^3\)

By the power rule, the above expression can be rewritten as,

\(n=(5)^{3\times3}\\n=(5)^{9}\\n=5^9\)

Thus, the number as a power of 5 which is obtained by the number 125^3 using the power rule and simplifying is 5⁹.

To evaluate the trigonometric function f(t) = sin t at t = 7π/6, we substitute t = 7π/6 into the function and calculate the value. The answer will be expressed as a simplified fraction, if necessary.

To evaluate the trigonometric function f(t) = sin t at t = 7π/6, we substitute t = 7π/6 into the function: f(7π/6) = sin(7π/6). The sine function evaluates the ratio of the length of the side opposite the given angle to the hypotenuse in a right triangle. In this case, the angle 7π/6 lies in the third quadrant (between π and 3π/2), where sine is negative.

To find the exact value of sin(7π/6), we can refer to the unit circle. The angle 7π/6 corresponds to a point on the unit circle with coordinates (-√3/2, -1/2) or (-0.866, -0.5). Therefore, f(7π/6) = sin(7π/6) = -1/2.

The value of sin(7π/6) is -1/2, which represents the ratio of the length of the side opposite the angle 7π/6 to the hypotenuse in a right triangle. Thus, f(7π/6) = -1/2.

To verify whether the function f(x) = \(x^{2}\)- 7 has an inverse function, we need to determine if it is a one-to-one function. An inverse function or an anti function is defined as a function, which can reverse into another function

A function is one-to-one if it passes the horizontal line test, meaning that no two distinct points on the graph of the function have the same y-coordinate. In this case, f(x) = \(x^{2}\)- 7 is a parabolic function that opens upward and has a minimum point. Since the parabola opens upward, it is not one-to-one. Therefore, f(x) = \(x^{2}\) - 7 does not have an inverse function. Now, to find (t-1)(a), we can use Theorem 5.9, which states that if a function f has an inverse function g, then f(g(x)) = x for every x in the domain of g. Since f does not have an inverse function, we cannot directly use this theorem. Hence, we cannot find (t-1)(a) using the given function f and the real number a because f does not have an inverse function.

The probability that a randomly inspected tire is within the recommended range is 1 or 100%. This means that every tire in the car should be within the recommended range, assuming the average psi is on target.

The manufacturer's recommended correct inflation range for the tire is between 30 psi and 34 psi. If we assume that the average psi of the tires is on target, we can calculate the probability that a randomly inspected tire is within the recommended range.

To calculate this probability, we need to know the total range of psi values that a tire can have. Since the recommended range is from 30 psi to 34 psi, the total range would be 34 psi - 30 psi = 4 psi.

Now, we need to determine how many values within this total range are considered within the recommended range. In this case, any psi value between 30 psi and 34 psi (inclusive) is within the recommended range.

Therefore, the probability of a randomly inspected tire being within the recommended range can be calculated as follows:

Number of values within the recommended range / Total range of values Since there are 4 psi values within the recommended range and the total range is 4 psi, the probability would be:

4 psi / 4 psi = 1

So, the probability that a randomly inspected tire is within the recommended range is 1 or 100%.

The equation of the ellipse in standard form is x²/25 + y²/9 = 1.

The eccentricity of an ellipse is given by the equation e=c/a. where e is the eccentricity, c is the distance between the center and focus of the ellipse and a is the length of the major axis.

Given, the eccentricity of the ellipse is 4/5 and the major axis is on the x-axis and the length is 10, and the center at (0,0).

The formula for the standard form of the equation of an ellipse whose center is at the origin is x²/a² + y²/b² = 1,where a and b are the semi-major and semi-minor axes of the ellipse respectively.

So the eccentricity is given as 4/5 = c/a, where c is the distance between the center and focus and a is the semi-major axis of the ellipse.

Since the major axis is on the x-axis and center at (0,0), the distance between center and focus is

\(c = a * e = 4a/5\).

The length of the major axis is given as 10, so the semi-major axis is

a = 5.

Therefore, the distance between center and focus is

c = 4×a/5 4

= 4*5/5

= 4.

The semi-minor axis b can be found using the formula,

b = √(a² - c²)

= √(5² - 4²)

= 3.

The equation of the ellipse in standard form can now be written as

x²/25 + y²/9 = 1.

In order to find the equation of an ellipse in standard form, we need to know the length of the major axis and eccentricity. The eccentricity of the ellipse is given as 4/5, and the length of the major axis is 10.

Since the major axis is on the x-axis and the center is at (0,0), we can use the standard form of the equation of the ellipse, x²/a² + y²/b² = 1, where a and b are the semi-major and semi-minor axes of the ellipse, respectively.

Using the formula for eccentricity, we can find the value of c, which is the distance between the center and focus of the ellipse.

Once we know the values of a, b, and c, we can write the equation of the ellipse in standard form

The equation of the ellipse in standard form is x²/25 + y²/9 = 1.

The Social Exchange Theory of interpersonal relationship satisfaction suggests that individuals are motivated to stay in a relationship as long as they feel that the rewards of the relationship are greater than the costs.

In the Social Exchange Theory of interpersonal relationship satisfaction, you would feel happiest in relationships when you feel that the rewards of the relationship equal or exceed its costs.

The Social Exchange Theory states that people evaluate their relationships in economic terms, with rewards being the benefits of the relationship and costs being the negatives. Rewards can include affection, attention, emotional support, sex, and companionship. Costs can include time, effort, money, and negative emotions such as stress, anxiety, and sadness.

According to the theory, individuals will be motivated to stay in a relationship as long as they feel that the rewards of the relationship are greater than the costs.

The opposite is also true; if individuals feel that the costs of the relationship are greater than the rewards, they will be motivated to leave the relationship.

Therefore, people are constantly evaluating their relationships to determine whether they are getting what they need from the relationship and whether it is worth continuing.
