Flying against the wind, an airplane travels 7040 kilometers in 8 hours. Flying with the wind, the same plane travels 10,440 kilometers in 9 hours. - What is the rate of the plane in still air?

- what is the rate of the wind?

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

The two square pyramids are similar. find the total volume of both pyramids if the ratio of their surface areas is 9/16

Point r divides in the ratio 1 : 5. if the coordinates of e and f are (4, 8) and (11, 4), respectively, what are the coordinates of r to two decimal places?
