This answer is rational, because the answer would be -9... which is rational.
Answer:
(b = 5 StartRoot 3 EndRoot)
and
(b = Negative 5 StartRoot 3 EndRoot)
Step-by-step explanation:
we have

we know that
The roots of the quadratic function are the values of x when the value of the function is equal to zero
so
For f(b)=0

Solve for b
Adds 75 both sides

take square root both sides

Simplify

therefore
(b = 5 StartRoot 3 EndRoot)
and
(b = Negative 5 StartRoot 3 EndRoot)

Answer:
12
Step-by-step explanation:
if we know we want a profit of at least 114, we need to solve for x.
if we put 12 for x we get the answer 117 and when we put 11 for x we get less than 114.
-0.5(12)^2 + 25(12)-111 = 117
Step-by-step explanation:
Storage Space of Shed = Volume of Shed.
Volume of Shed = Volume of Rectangular level
+ Volume of Triangular roof
Volume of Rectangular Level =
Length x Width x Height
=

Volume of Triangular Roof =
Area of Triangular side x Length
=

Volume of Shed = 576 + 144
=
