Is my answer correct?
write an exponential function to model this situation: a population of 420 animals decreases at an annual rate of 21%. then predict the value of the function after 5 years (to the nearest whole number).

The value of the function after 5 years would be 129.

Step-by-step explanation:

We have been that a population of 420 animals decreases at an annual rate of 21%. We are asked to write an exponential function for our given problem.

We know that an exponential function is in form , where,

a = Initial value,

b = For decay b is in form , where, r represents decay rate in decimal form.

Therefore, our required function would be .

To find the value of the function after 5 years, we will substitute in our function.

Therefore, the value of the function after 5 years would be 129.

idk lol xd

step-by-step explanation:

ez do it yourself lazy

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.
