Part A : y=$0.75m+$4.50
Part B : $8.25
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
I personally think it is <span>f(t) = 17.5 sin (π/4)(-t+6) + 17.5 </span>
Answer:
A. 2, 2, 5
Step-by-step explanation:
<u>DE:</u>
BA = 10
10 * 1/5 = 2
<u>EF:</u>
BC = 10
10 * 1/5 = 2
<u>DF:</u>
AC = 25
25 * 1/5 = 5
C
hope that it’s correct.
