The life zones on mount rainier, a mountain in washington, can be approximately classified by elevation, as follows
a. low elevation forest: above 1700feet to 2500 feet
b. mid elevation forest: above 2500feet to 4000 feet
c. subalpine: above 4000 feet to 6500feet
d. alpine: above 6500feet
write a compound inequality that represents the elevation range for each type of plant life.
i) trees in the low elevation forest zone
ii) flowers in the subalpine and alpine zones

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).
