Profit p(x) can be calculated as revenue minus cost. r(x) = 55x - 2x2 c(x) = 21x + 97 p(x) = - 2x2 + 34x - 97 calculate the x-value that maximizes profit.

8.5

Step-by-step explanation:

The vertex of a quadratic ax²+bx+c is located at x = -b/(2a). When the x² coefficient is negative, the vertex represents a maximum.

For P(x), the x-value of the maximum profit is ...

... x = -34/(2(-2))

... x = 8.5

Ithink the answer is discovery verbs because they are quite similar to the verb 'discovering'

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
