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 ≤ $4~is~=-1.$

A collection of dimes and nickels is worth $8.40 there are 106 coins how many of each are there

kotegsom [21]

There are 62 dimes and 44 nickels.

N + D = 106 (There are 106 coins in all.)
1 nickel = 5 cents.
1 dime = 10 cents.
5*N + 10*D = 840 ($8.40 = 840 cents)
N + D = 106 -------(1)
N = (106 - D)
5*N + 10*D = 840 ---------(2)
5*(106-D) + 10*D = 840
530 - 5*D + 10*D = 840
5*D = 840 - 530
5*D = 310
D = 310/5 = 62
Eq(1) N + D = 106
N + 62 = 106
N = 106 - 62
N = 44

A Ferris wheel has a diameter of 42 feet. It rotates 3 times per minite. Approximately how far will a passenger travel during a

UkoKoshka [18]

Hello!

First of all we will need to find the circumference, as it is the distance around the wheel. We will use 3.14 for pi.

42(3.14)=131.88

Now we multiply by three to see how far they go in a minute.

131.88(3)=395.64

Now we multiply by 5 to see five minutes.

395.64(5)=1974.2

A passenger will travel approximately 1978.2 feet in 5 minutes.

I hope this helps!
