5-|n-1|=-2<br><br> | | stands for absolute value
BlackZzzverrR [31]

Answer:

n = 8 or n = −6

Explanation:

First, isolate the absolute value:

5 − |n − 1| = −2

7 − |n − 1| = 0

7 = |n − 1|

Then, split this into two equations, since the result of the absolute value could be positive or negative:

7 = n − 1                           7 = −(n − 1)

8 = n                                7 = −n + 1

                                       n = −6

Answer:

  9 in

Step-by-step explanation:

 a = r·cos(180°/n)

We assume your problem statement is saying the radius is 10 inches. For a hexagon, n=6 and we have ...

 a = (10 in)cos(30°) ≈ 8.66 in

Rounded to the nearest inch, the apothem is 9 in.

The high school band is selling wrapping paper. It costs $4 each week to advertise the wrapping paper. The band buys each roll o
Setler79 [48]
For this case, the first thing we must do is define variables:
 x: rolls of wrapping paper in one week
 We now write the equation that models the profit of the band.
 We have then:
 P (x) = (3.50 - 2) x - 4
 P (x) = 1.50x - 4
 Answer:
 
An equation to model the amount of profit, P, the band makes from x rolls of wrapping paper in one week is:
 
P (x) = 1.50x - 4
