1. A rectangular brick has length 20 cm., width 10 cm., and height 5 cm. What is its volume? Now, let usconsider a right cylinder, i. e. a solid whose cross section is constant. Then the volume V of this solid is given by the cross-sectional area, A, and the height, h, and soV = Ah.

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
