(a) How many integers in the set {1, 2, . . . , 2000} are divisible by 15 or 20? (b) Find the permutation which has the inversion sequence < 3, 4, 1, 2, 1, 0 >.

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

In trapezoid efgh, m∠hef=(4x2+16)∘ and m∠gfe=(5x2+12)∘. find the value of x so that efgh is isosceles.
