Question

I need help with this please! I want someone to go through the steps with me, not tell me the answer. Thanks~! ^_^

Answer 1

This is the question

Answer 2

Wait this is the wrong question xD lolol

Answer 3

There we go

Answer 4

I'm glad you said that because I was having a tough time trying to answer the question without giving the answers.

Answer 5

XD sorry about that lol

Answer 6

On the second submission, what do you want to know? I'm kind of confused.

Answer 7

Ah, wrong question again T-T shoot. They all look the same to me. Sorry! >.<

Answer 8

Ok, I'm 100% sure this is the question. Those last two aren't it. I just was to know the steps on how to solve it.

Answer 9

Open Study quit on me for a bit, but I got back in.

Answer 10

Oh ok

Answer 11

This is a good question.

Answer 12

The first equation is a linear function

f(x) = 5x + 100 x is years (2) What is the value after 2 years?

Answer 13

So plug in 2 for x? Like this: f(2) = 5(2) + 100?

Answer 14

Yes.

Answer 15

Cool! So do we simplify that then?

Answer 16

What do you mean simplify? Just add them together.

The second one is an exponential function....

g(x) = 100(1.04)^x again x = 2 What is the value of g(x)?

Answer 17

Wait so the first one we just add? How would we do that? If we're using order of operations, wouldn't 5(2) have to be solved first? And then add that too 100?

Answer 18

Yes you are correct I was combining two operations.

Answer 19

Ok so how would you do that? Can you go step by step?

Answer 20

How do you do what?

Answer 21

Since you are offline, I assume you are having internet issues. Here is what you need to do to solve the equations. Hopefully, it is enough explanation.



f(2) = 5(2) + 100
g(2) = 100(1.04)^2


f(2) = 110
g(2) = 108.16

Then repeat the process for x = 20

f(20) = 5(20) +100
g(20) = 100(1.04)^20

Answer 22

Oh! Ok I see now! So you did f(2) = 5(2) + 100
f(2) = 10 + 100
f (2) = 110 right?

Answer 23

and for g(2) = 100(1.04)^2 it's
g(2) = 100(1.0816)
g(2) = 108.16
Thats how you did them both right? By using order of operations. @retirEEd

Answer 24

So then the account with the highest value in 2 years is 110, the first account yea? I'm going to try and solve for 20 years.

Answer 25

Keep going you are doing great.

Answer 26

:D okie! I'm solving for 20 years now! ^_^

Answer 27

Ok so the first account would be:
f(20) = 5(20) + 100
f(20) = 100 + 100
f(20) = 200
And the second account would be:
g(20) = 100(20)^2
g(20) = 100(400)
g(20) = 40,000
So in 20 years, the second account would have the highest value. Right @retirEEd

Answer 28

Am I right? @retirEEd

Answer 29

Oh shoot xD I did the second one wrong I just noticed

Answer 30

Is the first one correct though?

Answer 31

Redo the second one. You beat me to it.

Answer 32

lolol okie!

Answer 33

Ok so for the second one I got:
g(20) = 100(1.04)^20
g(20) = 100(2.191123143033419)
g(20) = 219.11

Answer 34

It would still be the highest value but am I correct? @retirEEd

Answer 35

Yes g(20) is higher than f(20).

Answer 36

Ok thank you! ^_^
