Question

Please help me with 3 algebra 1 questions! I will give a medal. I need help!!

Answer 1

Ya, what it?

Answer 2

I had posted them earlier but no one helped here they are

Answer 3

Check that problem, look at it and try to analyse that at first

Answer 4

Ok. What is an exponential growth function? Can you help me make one?

Answer 5

Exponential growth occurs when the growth rate of the value of a mathematical function is proportional to the function's current value..

Answer 6

oh! Lol I knew that

Answer 7

Thanks though

Answer 8

So how would I make one?

Answer 9

Okay, whats next.. to start of it, the frog one looks easy. wait. I'll frame the explanation

Answer 10

Ok

Answer 11

Let us have a exponential value.. say it is :

Answer 12

And now we'll see how "x" grows faster exponentially

Answer 13

Alright

Answer 14

How do we do that?

Answer 15

for y we'll put in values, as -3,-2,-1,0,1,2,3

Answer 16

and make a table, for keeping a check over its exponential growth. You get that bit right?

Answer 17

And then graph that!

Answer 18

Did you get that?

Answer 19

The first questions, says its simple and now you know how to do it (Of course you must know DOMAIN and RANGE!)

Answer 20

The third question is bit stiff, will help you through,
Dwayne is correct about the perimeter but incorrect about the area.
Let's say the side was of lngth sqrt(2).
The area is sqrt(2) times sqrt(2) = 2 which is a rational number.
The perimeter is 4s or 4 Sqrt(2) which is still irrational.

Answer 21

ok

Answer 22

The frog one sucks!!
Here's a function: y = 200(1.03^4)
200 is the initial number of frogs
1.03 means that the number of frogs is increasing by 3% per year
and the 4 = # of years, 4 years
Therefore y gives you the total number of frogs after 4 years, if you were to start with 200 frogs and they increase by 3% per year.

Answer 23

ok

Answer 24

Hey! Is that okay, did that help?

Answer 25

Yes, thank you!
