The surface area, s, of a sphere of radius r feet is s = s(r) = 4πr^2. find the instantaneous rate of change of the surface area with respect to the radius r at r = 8.

The hawaiian alphabet has 12 letters. how many permutations are posible for each number of letters?

Is appreciated! graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4^xg(x) = 4x^2options: x = -1x = 0x = 1x = 2

1. writing an equation for an exponential function by 2. a piece of paper that is 0.6 millimeter thick is folded. write an equation for the thickness t of the paper in millimeters as a function of the number n of folds. the equation is t(n)= 3. enter an equation for the function that includes the points. (-2, 2/5) and (-1,2)
