The final velocity, V, of an object under constant acceleration can be found using the formula V2= v2 + 2as, where v is the init

Whenever you work any "solve for" problem, you start by looking at what is done to the variable of interest. Here, a is multiplied by 2s and added to v². You must reverse these operations, generally in reverse order.

V² -v² = 2as . . . . . . . . subtract v²

(V² -v²)/(2s) = a . . . . . divide by the coefficient of a

Solved for a, the formula is ...

... a = (V² -v²)/(2s)

Which situation represents a non-proportional relationship?
denis-greek [22]

Answer:

Correct option:

"The total cost of renting a jet ski for $25 per hour plus a fee of $50."

Step-by-step explanation:

Proportional relationships are associations between two variables where the ratio of these two variables are correspondent. Or, in a proportional relationship, one variable is a constant value times the other variable. This constant is known as the "constant of proportionality".

The first three options represents a proportional relationship.

But the last option does not.

"The total cost of renting a jet ski for $25 per hour plus a fee of $50."

That is,

TC = 25·<em>h</em> + 50

The relationship is linear not proportional.

1. What is the value of x in the equation –6 + x = –2?
IgorC [24]
1. A. Add 6 to both sides to solve. 

2. D. If you simplify the a terms you will get 6 = 7 which is never true. 

3. A. Subtract 1.2m from both sides and then divide to solve. 

4. B. If you simplify you get 7 = 7 which is always true. 

5. D. Distribute the 2 and then add the 24 to both sides. Then divide to solve. 

6. A. Simplify the right side and then divide all by two. Then add 16 to both sides and divide by 4. 

7. 3y - 2

how much must be deposited today to have $45,000 in 5 years with a quarterly compounding and an APR of 7.3%
Alekssandra [29.7K]

Answer:

$31,341.81

Step-by-step explanation:

The compound amount equation is A = P(1 + r/n)^(nt), where P is the unknown principal, r is the annual interest rate, n is the number of compounding periods per year and t is the number of years.  We want to solve this for P:

       A

------------------- = P

(1 + r/n)^(nt)

Substituting the given numerical values;

     $45,000

 ---------------------------  =  P

   (1+0.073/4)^(4*5)

Using a calculator, we evaluate this expression, obtaining:  $31,341.81
