Answer:
$15,339
Step-by-step explanation:
C(x) = 0.5x² − 100x + 20,339
Since this is a parabola, the minimum cost is at the vertex:
x = -b / (2a)
x = -(-100) / (2 × 0.5)
x = 100
So the minimum cost is:
C(100) = 0.5(100)² − 100(100) + 20,339
C(100) = 15,339
36 and 144
Explanation
Two Angles are Supplementary when they add up to 180 degrees
Step 1
Let
x= angle 1
y= angle2
The measure of one angle is four times the measure of the other angle,then

x and y are supplementary angles , then

Step 2
use Equation (1) and (2) to find x and y

replace Equation (1) in Equation (2)

replace the value of y= 36 in equation (1) to find x

Hence, the answer is 36 and 144
The correct answer is 1. Hope this helps!!
State A has 4/35 of the largest cities in the country.
A has twice as many largest cities in the country than State B does.
This means State B has 2/35 of the largest cities in the country.
B. 82 because complementary angles equal 90˚ combined and 90-8=82
