Question

Help with equation/scenario

Answer 1

@Nnesha hey can you confirm my answer form ? I got like 3.989 so I'm going with that. I did it by hand so I just want someone to check.

Answer 2

x is an exponent ?

Answer 3

can you please explain or show ur work plz
how did you get that answer ? :=)

Answer 4

what was ur first step ?

Answer 5

hey?? :(

Answer 6

hey sorry afk again.
this is what I did

(30000=1.18^x * 15 30000=1.18^x * 500) I used scalar multiplying

Answer 7

@Nnesha

Answer 8

my book has a whole section on that in this lesson so I thought that was what I do but idk

Answer 9

i don't know why or how you separated de 15 and 5000\[\huge\rm 30000=15500(1.18)^x\]
you need to get rid of the 15500 so you can take ln both sides

Answer 10

divide both sides by 15500 and then take natural log

Answer 11

okay so 30000 / 15500 is 1.9354 and then just 1.18^x I think

Answer 12

Sorry if I'm not doing this right. Really trying though

Answer 13

yes right \[\huge\rm 1.935=(1.18)^x\] now take natural log both sides

Answer 14

isn't natural log just log10? I think someone told me that

Answer 15

ln is basically same as log same rules applies for both
but ln has base e and
and log_!0

Answer 16

log_10

Answer 17

I'm sorry can you show me how to set it up?

Answer 18

sure btw you can take ln or log you will get the same answer
if you take `ln` \[\huge\rm \color{ReD}{ln} 1.935=\color{red}{ln}(1.18)^x\]
or `log` \[\huge\rm \color{ReD}{log} 1.935=\color{red}{log }(1.18)^x\]

Answer 19

now apply the power rule \[\large\rm log_b x^y = y \log_b x\]

Answer 20

move the x exponent at front of log or ln
