he would hove to work 20 hours to meet the second job I think

To make the same total earnings at the first job as the second job (including benefits), Phillip would have to work an additional 4 hours (to account for the $100 benefits). If the workdays are 8 hours each, then for every two days (which is 16 hours) worked at job 2, Phillip would need to work an additional 4 hours at job 1, summing up to 20 hours.

This problem is about comparing the earnings from the two jobs. For the second job, Phillip earns $20 per hour and also gets benefits equivalent to $100 per pay period.

If Phillip wants to earn the same amount in the first job (which does not offer any benefits), we calculate how many hours he would need to work to earn an additional $100 (the value of the benefits).

To do this, we divide $100 (benefits of the second job) by the first job's hourly pay rate ($25) which results in 4 hours.

So, Phillip must work an additional 4 hours to make up for the benefits. Meaning, for any given number of hours he would work at the second job, he would need to work an extra 4 hours at the first job to get the same total earnings.

Therefore, the right answer is not among the choices given because we have an extra step to add to each option. If we consider a standard 8-hour workday, working at the second job for two days gives 16 hours with an additional $100 for benefits. To make the same in the first job, Phillip would need to work, 16 hours (from the second job) + 4 hours (to compensate for the $100 benefits) = 20 hours.

Answer:

sandals costed $32.55

Step-by-step explanation:

Final answer:

To find the cost of the sandals, subtract the cost of the T-shirt from the total cost. The equation 8.95 + c = 41.50 leads to c = 32.55, meaning the sandals cost $32.55.

Explanation:

The question asks us to find the cost of sandals that Tina bought, given the total cost of a T-shirt and the sandals combined, and the cost of the T-shirt alone. To solve for the cost c of the sandals, we start with the equation 8.95 + c = 41.50. We then isolate c by subtracting 8.95 from both sides of the equation:

c = 41.50 - 8.95

c = 32.55

Therefore, the cost of the sandals was $32.55.

Step-by-step explanation:

(7y)² = 7²×y² = 49y²

In order to simplify the expression (7y)^2, we need to apply the exponent to both the numerical coefficient and the variable inside the parentheses. Here's how to do it step-by-step:
1. The expression (7y)^2 denotes that everything inside the parentheses is to be squared. That means we multiply 7y by itself.
2. When squaring a product, we square each factor separately. So we have to square both the 7 and the y.
3. Squaring 7 gives us 7^2, which equals 49.
4. Squaring the variable y gives us y^2.
5. Now, we multiply 49 by y^2 to combine our results.
Putting these steps together, we see that (7y)^2 simplifies to 49y^2.
The final simplified expression without parentheses is 49y^2.

Answer:

Your salary will be $62,500.

Step-by-step explanation:

This is an arithmetic sequence with first term $45,000 and common difference $2,500.

The appropriate formula is a(n) = a(1) + (n-1)d, where a(1) is the first term, n is a counter and d is the common difference.

In this particular case, a(8) = $45,000 + (8-1)($2,500) = $62,500

Your salary will be $62,500.

A function assigns the values. Your salary after completing the 8th year within the company will be $62,500.

A function assigns the value of each element of one set to the other specific element of another set.

Given that the starting salary will be $45,000 while the salary will increase every year by $2,500. Therefore, the function that can represent the salary after (n-1) years can be written as,

y = $45,000 + $2,500(n-1)

Now, the salary after 8th year will be,

y = $45,000 + $2,500(n-1)

y = $45,000 + $2,500(8-1)

y = $62,500

The work done by the force field  on the object moving on the parabola y=7x^2 from (0,0) to (4,112) is calculated by integrating the force along the path. The total work done is found to be 224 units of work.

To find the work done by a variable force on an object moving along a given curve, we utilize the concept of a line integral in vector calculus. Given the force field F =  and the parabolic path described by y = 7x2, from point (0,0) to (4,112), we want to integrate the force field along the curve. To calculate this line integral, we parameterize the curve using x as the parameter, since y is already expressed as a function of x. We then express the force field in terms of x, evaluate the dot product of the force field and the differential of the position vector, and integrate from the start to the end of the curve.

The work, W, is found by integrating the dot product of F and dx from the initial to the final position:
W = \\int (F . dx).

In our case, the force field becomes F(x, y(x)) = F<7x2, x> = <7x2, x>. The differential displacement along the parabola, expressed in vector form, is dx = <1, 14x>dx because dy/dx = d(7x2)/dx = 14x. Thus, the infinitesimal work is dW = F .dx = 7x2 * 1dx + x * 14xdx = 21x2dx. Finally, we integrate from x = 0 to x = 4 to find the total work:

W = \\int_{0}^{4} 21x2dx = 7x3\\right]_{0}^{4 = 7 * 43 = 224.

Therefore, the work done by the force field along the parabolic path from (0,0) to (4,112) is 224 units of work.

The work required to move an object along the parabola y = 7x^2 from (0,0) to (4,112) under the force field F = <y, x> is approximately 149.33 units.

To find the work required to move an object along a curve under the influence of a force field, we can use the line integral of the force field along the curve. The line integral is given by the formula:

∫ F · dr = ∫ (F1 dx + F2 dy)

Given the force field F = <y, x> and the parabola y = 7x^2, we need to parameterize the curve to express it in terms of a single variable.

Let's parameterize the curve using x as the parameter:

x(t) = t

y(t) = 7t^2

Now, we can calculate the differential elements dx and dy:

dx = x'(t) dt = dt

dy = y'(t) dt = 14t dt

Substitute the expressions for F, dx, and dy into the line integral formula:

∫ F · dr = ∫ (y dx + x dy)

            = ∫ (7t^2 dt + t * 14t dt)

            = ∫ (7t^2 + 14t^2) dt

            = ∫ 21t^2 dt

            = 7t^3 / 3 + C

Evaluate the integral from t = 0 to t = 4:

Work = [7(4)^3 / 3] - [7(0)^3 / 3]

    = (7 * 64 / 3) - 0

    = 448 / 3

    ≈ 149.33

Therefore, the work required to move an object along the parabola y = 7x^2 from (0,0) to (4,112) under the force field F = <y, x> is approximately 149.33 units.

a) The amount after 2 years with continuous compounding is approximately $6539.48.

b) It will take approximately 2.32 years for the amount to reach $8000 with continuous compounding.

a) To calculate the amount after 2 years with continuous compounding, you can use the formula:

[tex]A = P \times e^{rt}[/tex]

Where:

A = the amount after time 't'

P = the principal amount (initial investment)

e = Euler's number (approximately 2.71828)

r = the interest rate (as a decimal)

t = the time in years

Given that P = $5800, r = 6% (0.06 as a decimal), and t = 2 years, we can now calculate the amount (A):

[tex]A = 5800 \times e^{0.06 \times 2}[/tex]

[tex]A=5800 \times e^{0.12}[/tex]

[tex]A=5800 \times 1.1275[/tex]

A=6539.48

Hence,  the amount after 2 years is approximately $6539.48.

b) To find how long it takes for the amount to be $8000, we need to solve for 't' in the formula:

[tex]A = P \times e^{rt}[/tex]

Given that A = $8000 and P = $5800, we can rearrange the formula:

[tex]e^{rt}=\frac{A}{P}[/tex]

[tex]e^{0.06t}=\frac{8000}{5800}[/tex]

Take logarithms on both sides:

[tex]0.006t=log(\frac{8000}{5800})[/tex]

[tex]0.006t=0.139[/tex]

t=0.139/0.06

t=2.327

Hence, it takes 2.32 years for the amount to be $8000.

After 2 years, the investment grows to approximately $6498.78. It will take around 5.37 years for the investment to grow to $8000.

We can use the formula for continuously compounded interest, which is A = Pe^(rt), where P is the principal amount ($5800), r is the interest rate (6% or 0.06), t is the time, and e is the mathematical constant approximated as 2.71828.

a) To find the amount after 2 years, sub in $5800 for P, 0.06 for r, and 2 for t to get: A = $5800 * e^(0.06*2). Evaluating this gives approximately $6498.78.

b) To find out when the amount will be $8000, we set A to $8000 and solve for t, getting: t = ln($8000 / $5800) / 0.06. Evaluating this gives approximately 5.37 years.
