1. Evaluate the integral by interpreting it in terms ofareas
from (- 1) to 4, absolute value of x
2. GIven that the integral 0 to 1 (21x sqrt(x^2+9)) dx = 70 sqrt10-189, then what is the integral from 1 to 0 (21u sqrt(U^2+9))du?
3. Suppose y = sqrt(2x+1), where x and y are functions oft.
(a) if dx/dt = 12, find dy/dt when x=4
(b) if dy/dt = 3, find dx/dt when x = 40
4. Find the linearization L(x) of the function at a.
f(x) = x^(3/4), a=81
