Answer 2

@Hero

Answer 3

I think it may be D but I'm not sure

Answer 4

Is there an x in there anywhere?

Answer 5

no sorry the problem meant to say 2^y=5

Answer 6

to me it doesn't make any sense

Answer 7

Ah. Hmmm. OK, do you know your basic log rules?

Answer 8

like how to convert it yeah it would be log_2(5)=y

Answer 9

when i graph that log i get a linear function of like 2.32

Answer 10

Ah, but now you have a y value. So, which graph has an input of 5 and an output of roughlu 2.32?

Answer 11

the last one?

Answer 12

Yep. So by using log rules to get it in the y= form, you have something to work with, and that leads you to only one answer that has the values you get. Also, this might help conceptually:

Answer 13

so its definitely the last one right? cause this is my final and I'm nervous lol

Answer 14

You know that using a site like this to get answers on a test is cheating?

Answer 15

I don't go on here to cheat i explain my answer and told you why i thought it was that. how is that cheating. If I simply went on here to get the answers then i would post all my 80 questions but i only posted this because i don't understand and if a person doesn't understand what they're doing you get help like open study where someone helps you. sorry but i don't call that a crime But anyways thank you

Answer 16

Sadly, the philosophy of tests is this: They are not learning tools. They are evaluation tools. You are only supposed to use what you already know on tests or the tools that are approved. Anything else is cheating, flat out, and OpenStudy works with the schools to help make sure cheaters get caught and punished.
