Question

Need help! Just want confirmation on what i think I have to do!

Answer 1

do as you may
and then when done
finalize it as you can and then rest

Answer 2

I think i just have to ad the numbers right? So
0.60m+0.25m=0.85m
18.95+4.90=23.85
c=0.85m+23.85

Answer 3

es, I did the math, and you are correct :)

Answer 4

*yes

Answer 5

thank you! One more question is that okay?

Answer 6

Yes :)

Answer 7

it's a different question saved in the same png

Answer 8

I think to find the price after 8 years I replace t with 8 and solve, I got $487

Answer 9

487.36 yes, rounded up to 487

Answer 10

yes that is right :)

Answer 11

it wants me to round to the nearest dollar so $487.

Answer 12

but how do I find the current price?

Answer 13

yes your still correct :)

Answer 14

I can see the substituting t for 1 is the price after 1 year, but I don't know how to get the current price

Answer 15

sub in 0 for t ?? Not 100% sure

Answer 16

the current price would be just to ignore the exponent 400 * 1.025

Answer 17

well.... 8 years from today means t = 8
so.. so today is year well... is not even a year, because that'd be 365 days later
today's year is 0, thus t = 0

Answer 18

then the price would ... OH! 400! because anything with an exponent of 0 is automatically 1!

Answer 19

wait no @jdoe0001 is correct, my bad lol

Answer 20

and yep you got it!! @AJLYAMBER96

Answer 21

so $400 right? just what it says in the problem?

Answer 22

yeap
well


not quite anything, but close, I mean \(\Large 0^1 \ne 1\) =)

Answer 23

okay thanks!!! uhm.. Idk who to give the best response to?

Answer 24

I agree ^^ current is 400

Answer 25

whomever you want lol :)

Answer 26

Waaiiitt 1 moorreeee lol I pretty much knew what to do this entire test, just didn't want to get the answers wrong

Answer 27

ok :)

Answer 28

f(x)=(1/4) ^x x values are -2,-1,0,1,2 I literally just plug in right?
First answer if plugging in -2 would be....
wait, okay so how would I multply this? because the exponent is a negative?

Answer 29

(-1/4)(-1/4)????

Answer 30

do you have answer choices?

Answer 31

no it's a graph

Answer 32

hmm, im not 100% sure but I would prolly end up doing this the way you are (-1/4)(-1/4) lol @e.mccormick

Answer 33

@alyssa_xo any ideas?

Answer 34

a^-x=1/a^x
so \(\dfrac{1}{4}^-2=\dfrac{1}{\dfrac{1}{4}^2}=\dfrac{1}{\dfrac{1}{16}}=16\)

Answer 35

alternatively, rewrite 1/4 as 4^-1

Answer 36

I went to mathway sadly. It gave 16. I'm right because (1/4)(1/4) is 1/16, the negative sign 1/-16 make it a positive 16/1=16

Answer 37

lol well then.
