## swiftskier96 Group Title Help!?!?!?!? 19. In a particular region of a national park, there are currently 330 deer, and the population is increasing at an annual rate of 11%. a. Write an exponential function to model the deer population. b. Explain what each value in the model represents. c. Predict the number of deer that will be in the region after five years.

Exponential Function \[y = ab^t\] a = initial population b = rate t = years y = population after t years

Ok. Thank you! :)

Okay, post what you get after figuring it out.

8. swiftskier96 Group Title

Ok.

9. swiftskier96 Group Title

y = 330(0.11)^5 Thats the equation i got when i plugged in the numbers. Now im solving it.

10. Hero Group Title

b = 1 + r

11. Hero Group Title

It should be y = 330(1.11)^5

12. swiftskier96 Group Title

Oh. Ok. Hold on a sec...

The first way i solved it was by doing 1.11^5 and that equaled 1.6850581551. Then i multiplied it by 330 and got 556.069191183. Then i tried solving it a different way by multiplying 330 and 1.11 and got 366.3. Then i did 366.3^5 and got 6594541312769.34543. Now im assuming the first way i solved it is correct.

There's ONLY one way to do it. It's called using order of ops.

15. swiftskier96 Group Title

Isnt my first way right? Or am i missing something?

Yes, but you should always remember PEMDAS, especially since you are doing math on this level. Knowing PEMDAS should be second nature by now.

I do know PEMDAS. Thanks for the help! :)
