A couple plans to invest money into an account that earns 9% interest, compounded quarterly, for their child's college education. What principal must be deposited by the parents in order to have $25,000 after 13 years?

$282.98

Step-by-step explanation:

For computing the principal amount we need to apply the present value function i.e to be shown in the attachment below:

Data provided that in question

Future value = $25,000

Rate of interest = 9%

NPER = 13 years × 4 quarters =  52 quarters

PMT = $0

The formula is shown below:

= -PV(Rate;NPER;PMT;FV;type)

So, after applying the above formula, the present value is $282.98

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
