Answer:
Price of widget to break even= $37.9
Step-by-step explanation:
We are told that the equation representing the amount of profit, y, made by the company, in relation to the selling price of each widget, x is;
y = -8x² + 348x - 1705
Now, the company will break even when it has made no profit. That is when, y = 0
Thus;
0 = -8x² + 348x - 1705
Rearranging,
8x² - 348x + 1705 = 0
Using quadratic formula ;
x = [-b ± √(b² - 4ac)]/2a
x = [-8 ± √(-348² - 4•1•1705)]/(2 x 8)
x = $5.63 or $37.87
We'll use $37.87 because it is the highest price for which no profit is made, and higher price means that we could sell least number of products to earn a certain amount of money.
We are told to approximate to nearest cent. Thus,
Price of widget = $37.87 ≈ $37.9
Answer:
We have to evaluate the function p with the numbers on the argument of them, that is:
p(-5) = -11887
p(3)= -191
Step-by-step explanation:
First we are going to evaluate the functions and then to replace x by the corresponding number on the argument:
p(-5)= 2 (-5)^5 -9(-5)^4 -2(-5)^2+12(-5) +2 = -11887
p(3) =2(3)^5-9(3)^5-2(3)^2+12(3)-2 =-191
