A prism with a base area of 5 ft² and a height of 10 ft is dilated by a factor of 65 . What is the volume of the dilated prism?

mina [271]

Answer:

The volume of the dilated prism is $86.4ft^3$ .

Step-by-step explanation:

The original prism has base area $5ft^2$ and a height of $10ft$ .

The volume of the original prism is $v=5\times 10=50ft^3$ .

The prism is dilated by a scale factor of $k=\frac{6}{5}$ .

To find the volume of the dilated prism, we multiply the volume of the original prism by $k^3=\frac{216}{125}$ .

$V=\frac{216}{125} \times 50ft^3$

$\Rightarrow V=86.4ft^3$

Solve the following system of equations and show all work. <br> y = x^2 + 3<br> y = x + 5

RUDIKE [14]

Since both of the equations are equal to y...set them equal to each other.. So it will then be

x^2+3=x+5
-3 -3
x^2=x+2 ---> x^2-x-2
(x-2) (x+1)
x=2,-1
