Answer:
B. 1.-1,-2
Step-by-step explanation:
Substitute g(x)=0
Move the expression to the left
Factor out -x^2 from the expression
Factor out (x+2) from the expression
When the product of the factor equals 0, at least one factor is 0
Solve for x

D. She used the beach's ball's diameter when she should have used the radius
Step-by-step explanation:
To find the volume of the beach ball, using the volume of a sphere is the right formula to use, which is ⁴/3πr³.
The formula she used is correct.
Since the diameter of the ball is assumed to be 12 inches, what is needed to find the volume is the radius.
Radius (r) = ½(diameter) = ½(12) = 6 in.
This is where Emily made a mistake.
She used the diameter of the beach ball instead of its radius (r) which is needed in the equation.
She should have gotten,
V = ⁴/3(3.14)(6)² = 904.32 cubic inches
