So you have to find 15 percent of 900 which would be 135
Answer:
height=6 ft
Step-by-step explanation:
-The volume of a rectangular prism is given by the formula:
![V=lwh](https://tex.z-dn.net/?f=V%3Dlwh)
#We make h the subject of the formula the solve for it:
![V=lwh\\\\\frac{V}{lw}=h\\\\\therefore h=\frac{V}{lw}](https://tex.z-dn.net/?f=V%3Dlwh%5C%5C%5C%5C%5Cfrac%7BV%7D%7Blw%7D%3Dh%5C%5C%5C%5C%5Ctherefore%20h%3D%5Cfrac%7BV%7D%7Blw%7D)
#Substitute to solve for height:
![h=\frac{V}{lw}\\\\=\frac{72}{2\times 6}\\\\=6\ ft](https://tex.z-dn.net/?f=h%3D%5Cfrac%7BV%7D%7Blw%7D%5C%5C%5C%5C%3D%5Cfrac%7B72%7D%7B2%5Ctimes%206%7D%5C%5C%5C%5C%3D6%5C%20ft)
Hence, the prism has a height of 6 ft.
Cross the y-axis in x=0
therfore:
if x=0; y=3*0+2=2; ⇒ P(0,2)
solution: P(0,2).
