Suppose a long term investment is modeled by the exponential function v(t) = 30(25)t/20 where v(x) is the total value after t year. what does 25 represent in equation?
a. the interest rate
b. the growth factor
c. the initial deposit
d. the number of years

Option: b is the correct answer.

b.  The growth factor

Step-by-step explanation:

We are given a expression that represents the investment made.

The  long term investment is modeled by the exponential function:

where,

V(t) is the total value after t year.

The constant '25' here represents the growth factor by which our value is increasing each year.

constant '30' represents the initial value i.e. the investment made.

Hence, option: b is the correct answer.

b. The growth factor

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

r = 78539458390583095803458309458039485093485 or just 3
