Two friends, haley and kristen, are growing out their hair. they plan to cut it off at a certain point and donate it to a charity that makes wigs for people with cancer. haley's hair is already 19 centimeters long and grows at a constant rate of 1 centimeter per month. kristen's hair is 11 centimeters and growing at a speed of 3 centimeters per month. if the girls get their hair cut on a certain day, they will have exactly the same length to donate. how long will their hair be? how long will that take?

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a, b and c integers and a> 1
