Height of the cross-section

Height of prism (H) = 2.5 cm

Step-by-step explanation:

Given:

Base of rectangle (b) = 4 cm

Length of rectangle (l) = 7 cm

Volume of prism = 35 cm³

Find:

Height of prism (H)

Computation:

Volume of prism = 1/2 × b × l × H

35 = 1/2 × 4 × 7 × H

35 = 14 × H

Height of prism (H) = 2.5 cm

i think is g(1)=-1.

hope that i can

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
