Calculations:

All numbers rounded

Q2

The exponential growth model for bacteria:

B- number of bacteria, x- number of hours, 1.8 - growth factor

Calculations:

All numbers rounded

Q3.

The exponential growth model for fish:

F- number of fish, x- number of months, 1.02 - growth factor

Calculations:

All numbers rounded

a) F(12) = 821(1.02)¹² = 1041

b) F(120) = 821(1.02)¹²⁰ = 8838

All numbers rounded

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
