Step-by-step explanation:

what is so special about 13 ?

the other problems you understand and can do ?

and then you don't understand 13 ?

that is really strange.

anyway, remember, when dividing by a term with exponent we subtract that exponent.

in other words we have

5/2 × x^(-3 - -6) = 5/2 × x^(-3 + 6) = 5/2 × x³ = 5x³/2

On a map the key indicates that 1/4 inch = 1/2 mile. if two cities on themap are 4 1/2 inches apart what is the distance between

Ilya [14]

Let the actual distance be x mile.
1/4 inch = 1/2 mile
9/2 inch = x mile
(9/2)/(1/4)=x/(1/2)
18=2x
x=9

the actual distance is 9 mile.

Pat invested x dollars in a fund that paid 8% annual interest, compounded annually. Which of the following represents the value,

uysha [10]

Answer: D. $(1.08)^5\times x$

Step-by-step explanation:

The formula to find the compound amount (investment plus interest ) at the end of t years :

$A= (1+r)^t\times P$ (1)

, where r= rate of interest ( in decimal)

P= Initial amount.

As per given , we have

P = x dollars

r = 8% = 0.08

t = 5

Put all the values in (1) , we get

$A= (1+0.08)^5\times x$

$A= (1.08)^5\times x$

Therefore , the the expression that represents the value, in dollars, of Pat's investment plus interest at the end of 5 years :

$(1.08)^5\times x$

Hence, the correct answer is D. $(1.08)^5\times x$
