Model the pair of situations with exponential functions f and g. Find the approximate value of x that makes f(x) = g(x). f initial value of 700 decreasing at a rate of 12%
g: initial value of 80 increasing at a rate of 12%
Write the exponential function for f.

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
