The value of the integral ∫c f ds is (√3/2) t₀²

The given integral is  ∫c f ds

where f (x,y,z) = z and c (t) = (t cos t, t sin t, t) for 0 ≤ t ≤ t₀.

To find the integration, we first need to find the derivative of the position vector

r(t) = (t cos t)i + (t sin t)j + tk.

Now, 

r'(t) = cos t i + sin t j + k

Integrating r'(t) between the limits of 0 and t₀, we get

r(t₀) - r(0) = cos t₀ i + sin t₀ j + k - (i + 0 j + 0 k)

= (cos t₀ - 1)i + sin t₀ j + k

= c(t₀) - c(0)

Now, ||r'(t)|| = √(1² + 1² + 1²) = √3

The given integral is∫c f ds = ∫₀^t₀ z √(dx/dt)² + (dy/dt)² + (dz/dt)² dts = ∫₀^t₀ t √3 dt = (√3 t²/2)|₀^t₀ = (√3/2) t₀²

Thus, the value of ∫c f ds is (√3/2) t₀².

The quadratic function of best fit for the data is given as follows:

h(t) = -0.004t² +1.032t + 5.667.

Using this function, the initial height of the shot is of 5.67 feet.

The input and the output of the data are given as follows:

As the input increases, the output increases and then it decreases. Since this behavior of increase/decrease is not uniform over the entire domain of the relation, a quadratic function best models this data.

To find the quadratic function of best fit, we insert the points (input,output) into a calculator, from point (20, 25) to point (200,64).

Inserting the points into the calculator, the function is defined as follows:

h(t) = -0.004t² +1.032t + 5.667

The height in which the shot started its flight is given by the height when t = 0, hence:

h(0) = -0.004(0)² + 1.032(0) + 5.667 = 5.667 feet = 5.67 feet (rounded to the hundredths place).

Answer:

all real numbers

Step-by-step explanation:

-(2x + 4) + x = 3x − 4x − 4

Distribute the negative sign on the left side. It is the same as having a -1 to the left of the parentheses.

-1(2x + 4) + x = 3x − 4x − 4

-2x - 4 + x = 3x - 4x - 4

Combine like terms on the left side. Combine like terms on the right side.

-x - 4 = -x - 4

Add 4 to both sides.

-x = -x

Add x to both sides.

0 = 0

You end up with a true equation. Therefore, there is an infinite number of solutions. Every real number is a solution.

The probability that an elementary or secondary school teacher selected at random from this city is a female or holds a second job is 0.77, the correct answer is a.

To find the probability that an elementary or secondary school teacher selected at random from this city is a female or holds a second job, we can use the inclusion-exclusion principle.

Let's denote:

P(F) = Probability of being a female

P(S) = Probability of holding a second job

From the given information:

P(F) = 0.68

P(S) = 0.38

P(F ∩ S) = 0.29 (Probability of being a female and holding a second job)

Using the inclusion-exclusion principle, the probability of the union (female or holding a second job) is given by:

P(F ∪ S) = P(F) + P(S) - P(F ∩ S)

Substituting the values:

P(F ∪ S) = 0.68 + 0.38 - 0.29

P(F ∪ S) = 0.77

Therefore, the probability that an elementary or secondary school teacher selected at random from this city is a female or holds a second job is 0.77. Hence, the correct answer is a. 0.77.

GTT's expected market share is 45.45%, NCJ's expected market share is 31.82%, and Dash's expected market share is 22.73%. these percentages add up to 100%, as expected.

To find the long-run expected market share for each company, we need to use the concept of steady-state or equilibrium. In the long run, the market share of each company will remain constant if the number of customers gained is equal to the number of customers lost. This means that the rate of change of each company's market share will be zero.

Let's define the market share of each company at any point in time as follows:

GTT's market share = SGTT

NCJ's market share = SNCJ

Dash's market share = SDash

We can write the equations for the rate of change of each company's market share as follows:

dSGTT/dt = -0.2 SGTT + 0.05 SNCJ + 0.25 SDash

dSNCJ/dt = -0.05 SNCJ + 0.05 SGTT + 0.15 SDash

dSDash/dt = -0.15 SDash + 0.25 SGTT + 0.15 SNCJ

Note that the negative coefficients represent the percentage of customers lost by the company, and the positive coefficients represent the percentage of customers gained by the company.

To find the steady-state values of SGTT, SNCJ, and SDash, we need to set the rate of change of each company's market share to zero:

-0.2 SGTT + 0.05 SNCJ + 0.25 SDash = 0

-0.05 SNCJ + 0.05 SGTT + 0.15 SDash = 0

-0.15 SDash + 0.25 SGTT + 0.15 SNCJ = 0

We can solve these equations to get the steady-state values of SGTT, SNCJ, and SDash:

SGTT = 0.4545

SNCJ = 0.3182

SDash = 0.2273

Therefore, the expected long-run market share for each company is as follows:

GTT's expected market share: 45.45%

NCJ's expected market share: 31.82%

Dash's expected market share: 22.73%

Therefore, these percentages add up to 100%, as expected.

Answer:

Step-by-step explanation:

Multiply the exponents and simplify

The value of function at x = 36 is 34.12.

To find the cost of mailing an object that weighs 36 pounds, we can substitute the value of x into the function f(x) = 5.32 + 0.80x.

The function f(x) = 5.32 + 0.80x represents a linear relationship between the weight of the object (x) and the cost (f(x)) with a base cost of $5.32 and an additional cost of $0.80 per pound. By plugging in the value of 36 into the function, we can calculate the specific cost for that weight.

Plugging in x = 36, we have:

f(36) = 5.32 + 0.80 * 36

Simplifying the expression:

f(36) = 5.32 + 28.8

f(36) = 34.12

Therefore, f(36) is equal to 34.12. This means that it would cost $34.12 to mail an object weighing 36 pounds according to the given function.

Answer:

6 yds

Step-by-step explanation:

If we label the shorter side as x, the longer side can be represented as 2x + 2. Now, we can write an equation to model the situation. The area of a rectangle is the sides multiplied by each other:

84 = x(2x + 2)

84 = 2x^2 + 2x

Since all terms are divisible by two, we can divide both sides by it:

42 = x^2 + x

We can write the quadratic equation in standard form:

x^2 + x - 42 = 0

Now, we can factor. We are looking for numbers that multiply to -42 and add to 1. These numbers are 7 and -6. Factored the equation would be written as followed:

(x + 7)(x - 6) = 0

Using the zero-product property, we can obtain two equations and solve them:

x + 7 = 0

x  = -7

x - 6 = 0

x = 6

Since the side of a rectangle can't be negative, the answer must be 6 yds.

By using function notation, you should write an equation or expression for each statement as follows;

The temperature at 12 p.m ⇒ f(12).

The temperature was the same at 9 a.m. and at 4 p.m ⇒ f(9) = f(16).

It was warmer at 9 a.m. than at 6 a.m ⇒ f(9) > f(6).

Some time after midnight, the temperature was 24 degrees Celsius. ⇒ f(t) = 24.

In Mathematics, a function simply refers to a mathematical expression which can be used for defining and showing the relationship that exist between two or more variables in a data set.

This ultimately implies that, a function typically shows the relationship between input values (x-values or domain) and output values (y-values or range) of a data set, as well as showing how the elements in a table are uniquely paired (mapped).

For the statement, "The temperature was the same at 9 a.m. and at 4 p.m." we have:

4 p.m = 12 + 4 = 16

In function notation, we have:

f(9) = f(16) or f(16) = f(9)

Answer:

x = 5

Step-by-step explanation:

So the perimeter of a square is 4 times the side length.

4 (x+3) = 32 is the equation we can make out with the given information.

Solve for x:

Distribute the 4 to the terms inside the parenthesis;  4x + 12 = 32

Subtract 12 from both sides;  4x = 20

Divide both sides by 4;  x = 5

By isolating x, we get 5 as the value of x.
