I need help with this calculus problem. If the revenue function, R(x) = (280 – 2x)(50 + x) and the cost function, C(x) = 4(4000 – 2x), find P(x). Your answer will be in quadratic form. For example, −ax 2 + bx – c

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

answer: 193

explanation:

200-7 = 193
