48. THOUGHT PROVOKING You teach a math class and assign a weight to each component of the class. You
determine final grades by totaling the products of the
weights and the component scores. Choose values for
the remaining weights and find the necessary score on
the final exam for a student to earn an A (90%) in the
class, if possible. Explain your reasoning.

Aquadratic equation in standard from is written ax^2= bx+c, where a, b and c are real numbers and a is not zero?

Ihonestly have no clue if it's each or none.

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).
