An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 2106 feet and Plane B is just taking off. Plane A is gaining altitude at 30.25
feet per second and Plane B is gaining altitude at 70.75 feet per second.
How many seconds will pass before the planes are at the
same altitude?
Il seconds
What will their altitude be when they're at the same
altitude?
I feet

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.
