Barrett works at an ice cream shop. the function f(x) represents the amount of money barrett earns per gallon of ice cream, where x is the number of gallons of ice cream he makes. the function g(x) represents the number of gallons of ice cream barrett makes per hour, where x is the number of hours he works. show all work to find f(g( and explain what f(g(x)) represents. f(x) = 2x2 + 4 g of x equals the square root of the quantity 3 x cubed

tex]f(g(x))= 2(3x^{3})+4\\f(g(x))=6x^{3}+4[/tex]

Step-by-step explanation:

Given

We will fnd f(g(x)) first. So,

The square root will be cancelled out with the square,

we will get

so we can see that f(g(x)) gives us the total amount of money Barrett earns for working x hours ..

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
