Answer:

Option A

Step-by-step explanation:

The domain of a function is the set of all numbers that has an image in the co domain. It means that those elements are mapped to other elements and give output values.

From the figure we see that all the elements in $x$ are marked to other elements in $f(x)$ . So, the domain would be:

$\{-4, -1, 0, 2, 7\}$

Hence, Option A.

Can anyone help me with this page i can’t find the answers

Dvinal [7]

1) f(x)=2x

when x=3 then f(x) =3×2=6

when x=4 then f(x)=4×2=8

2)At y=35(no. of mangoes),x corresponds to y=60(amount)

so$60, amount he need to spend!

3) f(x)= x+2

for x=1, f(x)=1+2=3

for x=2,f(x)=2+2=4

Julie and her brother go to Atlanta to ride the SkyView Ferris wheel. It measures 200 feet in diameter.

worty [1.4K]

Answer:

Part A) Circumference

Part B) $C=\pi D$

Part C) The distance traveled in one rotation is 628.32 feet

Step-by-step explanation:

Part A) we know that

The distance around the circle is equal to the circumference.

The Ferris Wheel have a circular shape

To find out the distance around the Ferris Wheel you should use the circumference

Part B) What is the formula needed to solve this problem?

we know that

The circumference is equal to multiply the number π by the diameter of the circle

$C=\pi D$

Part C) What is the distance traveled in one rotation?

we know that

One rotation subtends a central angle of 360 degrees

The distance traveled in one rotation is the same that the circumference of the Ferris wheel

we have

$D=200\ ft$ ----> diameter of the Ferris wheel

substitute in the formula of circumference

$C=\pi (200)\\C=200\pi\ ft$

assume

$\pi=3.1416$

$C=200(3.1416)=628.32\ ft$

therefore

The distance traveled in one rotation is 628.32 feet
