The measurement ol the edge of a cube is found to be 12 inches, with a possible error of 0.03 inch. use differentials to approximate the maximum possible propagated error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.)

Step-by-step explanation:

Hello!

In order to solve this problem we'll start by writing down the data below:

Now we are going to define two functions, the volume and the surface area of the cube in function of the measured edge a:

volume:

surface area:

Ok so, for the maximum possible propagated error in computing the volume of the cube. We derivate V(a) and obtain:

solve for dV and compute:

There it is for the volume...

Now we'll proceed to do exactly the same but with the function S(a):

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
