2. A doctor believes that the average teen sleeps on average no longer than 10 hours per day. A researcher believes that teens on average sleep longer.

Suppose that f(0) = −3 and f '(x) ≤ 8 for all values of x. how large can f(4) possibly be? solution we are given that f is differentiable (and therefore continuous) everywhere. in particular, we can apply the mean value theorem on the interval [0, 4] . there exists a number c such that

Which matrix multiplication is possible?

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?
