Your college newspaper, The Collegiate Investigator, has fixed production costs of $70 per edition and marginal printing and distribution costs of $0.7 per copy. The Collegiate Investigator sells for $0.9 per copy. (a) Write down the associated linear cost, revenue, and profit functions (in dollars) where x represents the number of copies of the newspaper made and sold.
C(x) =

R(x) =

P(x) =

(b) What profit (or loss) results from the sale of 500 copies of The Collegiate Investigator?
$

(c) How many copies should be sold in order to break even?
copies

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.

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."

answer:  

123455421

step-by-step explanation: easy

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
