Answer:
A graphing calculator can do quadratic regression on the given points. It tells you the cost function is
.. c(x) = (1/2)x^2 +8x +10
Then c(12) = 178
The cost function predicts the total cost of producing 12 camera cases is $178.
Step-by-step explanation:
<3 follow
Parallel lines will have the same slope
y - y1 = m(x - x1)
slope(m) = 2
origin (0,0)...x1 = 0 and y1 = 0
now we sub
y - 0 = 2(x - 0) <===
Answer:
e
Step-by-step explanation:
Factor 3x^3-10x^2+3x+10
=(x-2)(3x^2-4x-5)
