Rewrite y = 2(10)t/12 in the form y = a(1+r)t or y = a(1 - r). Round the value of r to
the nearest ten thousandth. Then tell whether the model represents exponential growth or
exponential decay.

Step-by-step explanation:

Given that:

To rewrite the model in the form or

is in the form or where r=0.2115.

Since 1.2115>1, the model represents an exponential growth.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
