The formula for volume of a cone = PI x r^2 x h/3

PI = 3.14

r = 8.5/2 = 4.25

h = 4.5

Volume = 3.14 x 4.25^2 x 4.5/3

Volume = 3.14 x 18.0625 x 1.5

Volume = 85.074375

Rounded to the nearest hundredth = 85.07 cubic cm.

Can someone help me with my algebra?
SIZIF [17.4K]

Answer:

The top graph

Solutions:

-2

0

Step-by-step explanation:

The given quadratic function in factored form is

f(x) =  - (x + 2)(x - 2)

This is a parabola that has x-intercepts at (-2,0) and (2,0)

This parabola opens downward because the leading coefficient is less than 1.

The second function is

g(x) = 2 |x  + 2|

This is an absolute value function with vertex at (-2,0).

Therefore the graph that shows the solution to f(x)=g(x) is the top graph.

Hence the solution is x=-2,x=0
