8. The profit P (in dollars) generated by selling x units of a cer- tain commodity is given by the function P(x) = -1500 + 12x 0.004.r- What is the maximum profit, and how many units must be sold to generate it? Show your work.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

168

step-by-step explanation:

i am pretty sure that the answer is 168

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221
