Determine the present value P you must invest to have the future value A at simple interest rate r after time t. A $9000.00, r 1
denis-greek [22]

Answer:

P = $6923

Step-by-step explanation:

The simple interest formula is given by

1) I = principal  *interest rate * time period

where I is the interest

The amount due after the time period is given by:

2) T = principal + I

After three months, you have $9.000, so T = 9000. The present value P is the principal. We have that:

9000 = P + I

I = 9000 - P

In our problem, we have that the time period is 3 months and out interest rate is 10%.

Replacing in 1)

9000 - P = P*0,1*3

9000 = 0.3P + P

1.3P = 9000

P = $6923

So the present value P is $6923

Fittoniya [83]

Answer:

C)√ 72

Step-by-step explanation:

We will Simplify the radical by breaking the radicand up into a product of known factors.

When we do this, we figure out that...

A.√ 49 = 7

B.√ 64 = 8

D.√ 121 = 11

BUT C) is different.

√ 72 can not be divided into any whole number an exact amount of times.

So instead, this can be solved by writing it as shown:

Exact Form:

6 √ 2

Decimal Form:

8.48528137
