Question

A young channel catfish weighs about 0.1 pound. During the next 8 weeks, its weight increases by about 23% each week. Write an exponential growth function that represents the weight of the catfish after t weeks during the 8-week period.

*Please Help* 

Answer 1

The equation is

`y=0.1(1.23)^t`.

Step-by-step explanation:
Exponential functions are given by y=a(1+r)ˣ, where a is the initial amount, r is the rate of growth, and x is the amount of time. In our case, a=0.1, r=0.23 and t=x.

This gives us

`y=0.1(1+0.23)^t`
which simplifies to

`y=0.1(1.23)^t`.
