Chantel drew a picture of her dog on a piece of paper that is 12 centimeters long. She used a copy machine to enlarge her drawin

g. She used the 115% setting to make each new copy. She then used each new copy to generate the next copy, using the same copier setting. Enter a recursive formula that will give the length of each new copy. Answer is 1.15an-1. I just don't understand how to get that.

Given:
Piece of paper that is 12 cm long
Copied her drawing with 115% setting.
Uses each new copy to generate the next copy.

A recursive formula is a formula wherein each term is a function of the preceding term. 

The recursive formula of the above scenario is 1.15n-1

n is the number of the copy.
1.15 is the 115% in decimal form
n-1 is the number of the preceding copy

Grandma has just finished baking a large rectangular pan of brownies. She is planning to make rectangular pieces of equal size a
Nikitich [7]

Answer: 60

Step-by-step explanation:

Let the side lengths of the rectangular pan be m and n. It follows that (m-2)  (n-2)= mn/2

So, since haf of the brownie pieces are in the interior. This gives 2 (m-2) (n-2) =mn

mn- 2m - 2n- 4 = 0

Then Adding 8 to both sides and applying, we obtain (m-2) (n-2) =8

Since now, m and n are both positive, we obtain (m,n) = (5,12), (6,8) (up to ordering). By inspection, 5. 12 = 60

which maximizes the number of brownies in total which is the greatest number.

Hope that helped! =)

What is the absolute value of –6? Use the number line to help answer the question. A number line going from negative 7 to positi
drek231 [11]
<h3>Answer:  6</h3>

Mark the locations -6 and 0 on the number line. Note that going from -6 to 0, or vice versa, will take exactly 6 steps. Put another way, the distance between 0 and -6 is 6 units. Absolute value represents distance, so it is never negative.

We say |-6| = 6

Effectively, all we're doing is removing the negative sign.
