A study is done on the number of bacteria cells in a petri dish. Suppose that the population size P() after I hours is given by the following exponential function.
P (t) = 1600(1.04)'
Find the initial population size.
0
Does the function represent growth or decay?
O growth O decay
By what percent does the population size change each hour?
Х
5 ?

1600

growth

4%

Step-by-step explanation:

To solve this question, you must know what the equation really means.

P = population

t = time

1600 = initial population size

1.04 = is the percentage growth, (growth because it is greater than 1.)

So, the initial population size is 1600.

It is growth because the percentage is greater than 1.

(1.04 = 104%, 104%-100%=4%)

The population changes by 4%

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

-232
