G(f(x))=? g(x)=2x^2-4? hope this is what you mean
g(f(x))=2(4x+2)^2-4
g(f(x))=2(16x^2+16x+4)-4
g(f(x))=32x^2+32x+8-4
g(f(x))=32x^2+32x+4

There are 60 cars in a used car lot.
PilotLPTM [1.2K]

Answer:

Honda made 32 cars

Step-by-step explanation:

Total no. of cars = 60

car made by ford = 3/10 of total no of cars

car made by ford = 3/10 of 60 = 3/10* 60 = 18

car made by General Motors = 1/6of total no of cars

car made by General Motors = 1/6 of 60 = 1/6* 60 = 10

No of cars made by Honda = Total no. of cars - car made by ford - car made by General Motors

No of cars made by Honda = 60 - 18 - 10 = 32

In this lot, Honda made 32 cars.

alex41 [277]

Answer:

4

Step-by-step explanation:

14 feet is the perimeter

to get the perimeter you need to add alll the sides together

if the length is 3 feet then u add

3 + 3 for both sides

then you subtract 6-14

and that is 8

then you divide it by 2 becuase u need it for one side not both sides combined

Answer Step-by-step explanation:

\huge\boxed{A)-1}

The~average~rate~of~change~of~the~given~quadratic~function~on~the interval~0 ≤ x ≤4 is~the~slope~of~the~secant~line~connecting~the~points~(0,f(0))~and~(4,f(4)).

The~average~rate~of~change~is:

=\frac{f(4)-f(0)}{4-0}

Now,from~the~graph,f(0)~is~0~and~f(4)~is~-4.

We~plug~in~these~values~to~obtain;

=\frac{-4-0}{4-0}

And~then,this~simplifies~to:

=\frac{-4}{4}

which~is~obviously:

=-1

Thus,~the~average~rate~of~change~for~the~given~quadratic~function whose~graph~is~shown~on~0 ≤ x ≤ 4~is~=-1.
