Answer:
A
Step-by-step explanation:
We are given that a function

We have to find the next step in the process and what is the extreme value .
By adding and subtracting 16 then we get


By using the formula

The given function is the equation of parabola .
By comparing with

Where vertex=(h,k)
Vertex=(h,k)=(-4,-10)
Substitute x=-4
Then, we get

Hence, the extreme minimum value of function =-10
Option A is true.
The answer is positive 13
Answer:
$53.20
Step-by-step explanation:
First, you need to find 24% of $70.
Change the percent to a decimal.
24% to .24.
Multiply that times 70.
.24 x 70 = 16.8
This will be the amount of money taken off the original price, so you will subtract it from the $70.
70 - 16.8 = 53.2
Therefore, the retail price is $53.20
