PLEASE HELP ME!!What is |9|?

C.
9

D.
18

Answers

Absolute value takes the distance of the number, not the direction. That means that the absolute value of a number would always be a positive. 

|9| = 9

Answer: 9

Because absolute value means the number distance away from zero, [9] is 9.
Answer: C. 9
Xtra info: [-9] would just mean 9, that is how far it is away from 0.

58. Jordan biked 2 ¾ miles ON monday=> Then on Wednesday he biked twice as many miles as he did on Monday=> 2 x 2 and ¾=> 2 ¾ convert to decimals = 2.75=> twice as 2.75 = 2(2.75)On Friday he biked 8 ¼ miles.=> 8 ¼ = 8.25=> he biked 5.5 miles miles on Wednesday=> 8.25 – 5.5 = 2.75Therefore, he biked more than 2.75 miles on Friday compare to Wednesday.

amber invested 25000 at 2% for 3 years compound simiannually.Find future value at the end of 3 years?

Answers

Use the compound interest formula:

A = P(1+r/n)^(nt). Here, P = $25000, r = 0.02, t = 3 and n = 2.

Then:

A = $25000(1 + 0.02/2)^(3*2)

= $25000(1.01)^6

= $26538.00 (future value at the end of 3 years)

First you use the compound interest formula which is: A = P(1+r/n)^(nt).

Plug in the number in this case being P = $25000, r = 0.02, t = 3 and n = 2.

A = $25000(1 + 0.02/2)^(3*2)

= $25000(1.01)^6

= $26538.00 (future value at the end of 3 years)
