There’s tutors for math i just asked a tutor for help lol
Answer:
B.40
Step-by-step explanation:
Answer:
$11,714
Step-by-step explanation:
C(x) = 0.7x² - 462x + 87,944
this is a quadratic equation that opens up
the vertex will be the minimum
From the quadratic formula the x coordinate of the vertex is
x = -b/2a
x = 462/(2 * 0.7)
x = 330
Plug in
c(330) = 0.7(330²) - 462(330) + 87,944
c(330) = 11,714
$11,714
180-40=140. 140/5 = 28
x= 28
angle B: 5(28) = 140
140 + 40 = 180
180=180
Two answers could be 1 & 5 or 2 & 6
