You were recently hired by a company and will recieve a starting salary of $45,000 per year. You will receive a $2,500 raise each year you are with the company. What will your salary be in your 8th year with the company?
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.
What is a Function?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

Miguel has started training for a race. The first time he trains, he runs 0.5 mile. Each subsequent time he trains, he runs 0.2 mile farther than he did the previous time. What arithmetic series represents the total distance Miguel has run after he has trained n times?
Answer:
[tex]0.4n+0.1n^2\ miles[/tex]
Step-by-step explanation:
The first time he trains, he runs 0.5 mile, then the first term of the arithmetic sequence is [tex]a_1=0.5.[/tex]
Each subsequent time he trains, he runs 0.2 mile farther than he did the previous time, then the difference of the arithmetic sequence is [tex]d=0.2.[/tex]
The nth term of the arithmetic sequence can be found using formula
[tex]a_n=a_1+(n-1)d,[/tex]
hence
[tex]a_n=0.5+0.2(n-1)\\ \\a_n=0.5+0.2n-0.2\\ \\a_n=0.3+0.2n.[/tex]
The total distance after Miguel has trained n times can be found using formula
[tex]S_n=\dfrac{a_1+a_n}{2}\cdot n,[/tex]
thus, the total distance is
[tex]S_n=\dfrac{0.5+0.3+0.2n}{2}\cdot n=\dfrac{0.8+0.2n}{2}\cdot n=(0.4+0.1n)n=0.4n+0.1n^2.[/tex]

Given the force field F, find the work required to move an object on the given orientated curve. F=<y,x> on the parabola y=7x^2 from (0,0) to (4,112)
[tex]y = 7 {x}^{2}[/tex]
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.

Phillip is looking at two different jobs. One has a higher hourly pay rate, while the other
offers benefits. The first job pays $25 an hour, while the second job pays $20 an hour.
Benefits from the second job are equivalent to $100 per pay period. How many hours per
pay period will Phillip have to work in the first job to make the same as the second job,
including benefits?
a. 10
b. 14
c. 20
d. 16
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.
Explanation: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.

An online service charges $3 for each downloaded movie, plus a monthly fee of $6.50. Which function represents this situation?
y = 3x - 6.50
y = 6.50x - 3
y = 3x + 6.50
y = 6.50x + 3
ANSWER
y = 3x + 6.50
EXPLANATION
The $3 for each downloaded movie is the unit rate of change.
This is represent the slope of the linear function that models this situation.
The monthly fee of monthly fee of $6.50 the constant rate.
It represents the y-intercept of the function.
The linear function is given by
[tex]y = mx + b[/tex]
The correct choice is y = 3x + 6.50
the answer would be C. y = 3x + 6.50, for every movie you buy (which is x), they would be 3$. therefore it would be 3x, and the monthly fee would just be added with that. :P

(7y)^2
Write your answer without parentheses.
Answer:
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.

The variable z is directly proportional to x, and inversely proportional to y. When x is 7 and y is 7, z has the value 2. What is the value of z when x= 10, and y= 12
Answer:
z = [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
Given z is directly proportional to x and inversely proportional to y then the equation relating them is
z = [tex]\frac{kx}{y}[/tex] ← k is the constant of proportionality
To find k use the condition x = 7, y = 7 and z = 2
k = [tex]\frac{zy}{x}[/tex] = [tex]\frac{2(7)}{7}[/tex] = 2

If you translate ABC to the left, you will put it entirely in quadrant II, so reflection across the y-axis will put it in quadrant I. Obviously, that is not the correct sequence of transformations.
If you translate ABC 3 units to the right, it will put line AB on x=2. Then reflection across the y-axis will put that vertical segment on x = -2, exactly where corresponding segment DE is located.
