A particular type of cell quintuples in every hour. The function y=5^x can be used to find another number of cells after X hours if there is 1 hour. Identify a, b and if it is growth or decay

The given function is

Notice that this is an exponential function with a positive base, which means is a growth function.

From the equation we know that and , which are the base (rate) and exponent, respectively.

For 1 hours, we have

Therefore, the first hour there are 5 cells.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
