Acharity organization had a fundraiser where each ticket was sold for a fixed price of \$70$70dollar sign, 70. they had to sell a few tickets just to cover necessary production costs. after selling 101010 tickets, they were still at a net loss of \$800$800dollar sign, 800 (due to the production costs). let p(n)p(n)p, left parenthesis, n, right parenthesis denote the net profit from the fundraiser ppp (measured in dollars) as a function of the number of tickets sold nnn. write the function's formula.

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
