72°
the sum of the exterior angles of a polygon = 360°
for a pentagon with 5 sides the
exterior angle =
= 72°
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
X is 65 because 65 is great and should always be the answer
The correct answer is y=1/2x-3
