4. SHIPPING The Overseas Shipping Company loads cargo into a container to be shipped around the world.
Th& volume of their shipping containers is determined
by the following equation.
x3 +21x2 +99x + 135
The container's height is x + 3. Write an expression
that represents the area of the base of the shipping
container.

The variable z is directly proportional to x, and inversely proportional to y. when x is 4 and y is 13, z has the value 1.2307692307692. what is the value of z when x= 9, and y= 20

Consider the function y = f(x)=3^x the values of f(1/2) and f(1/4). rounded to the nearest hundredth, are__and__ respectively
