Is the relation shown in the graph a function? Explain.

No, because of the vertical line test, putting a line top to bottom anywhere on the graph results in it going through two lines and not only one, therefore, it’s not a function
No it is not a function! If you put an imaginary line vertically and the line touches two horizontal lines at the same time it is not a function of that makes any sense lol

Decimal: 1.03125

Step-by-step explanation:

4 [tex]\frac{1}{8}[/tex] ×[tex]\frac{1}{4}[/tex]

Multiply 4 and 8 to get 32.

[tex]\frac{32+1}{8}[/tex] × [tex](\frac{1}4})[/tex]

Add 32 and 1 to get 33.

[tex]\frac{33}{8}[/tex] × [tex](\frac{1}{4})[/tex]

Multiply [tex]\frac{33}{8}[/tex] times [tex]\frac{1}{4}[/tex] by multiplying numerator times numerator and denominator times denominator.

Do the multiplications in the fraction

8x -(-5) = 29 To make the equation true, what is the value of x?

Answers

X=3 move constant to the right-hand side and change its sign
Subtract the numbers
Divide both sides by 8

Answer:

X = 3

Step-by-step explanation:

-(-5) is also the same as + 5, so the equation would be 8x + 5 = 29

Subtract 5 from both side of the equation

8x+5-5 = 29 -5

8x = 24

Then divide both sides by 8

The volume of a cylinder is 90 pi cm^3 . If the radius is 3cm, what is the height of the cylinder?
(pythagorean theorem)
Please help Ill give brainlist

Answers

Answer:

A) 10 cm

Step-by-step explanation:

You don't need the Pythagorean Theorem. You can simply use the formula for the volume of a cylinder and solve for the height:

[tex]V=\pi r^2h\\\\90\pi=\pi (3)^2h\\\\90\pi=9\pi h\\\\10=h[/tex]

Therefore, the height of the cylinder is 10 cm.

r=3cmh=?

[tex]\\ \tt\hookrightarrow V=\pi r^2h[/tex]

[tex]\\ \tt\hookrightarrow 3^2\pi h=90\pi[/tex]

[tex]\\ \tt\hookrightarrow \pi h=10\pi[/tex]

[tex]\\ \tt\hookrightarrow h=10cm[/tex]

2)Explain how you used benchmarking to find your answer to the previous question. Write 2 or more sentences. (i only need #2)

Answers

Answer:

Blue Ballon = 16

Yellow Ballon = 23

Green Ballon = 26

Red Ballon = 32

Total puffs = 1000

23y + 16(2y) + 32y + 26(y/2) = 1000

23y + 32y + 32y + 13y = 1000

100y = 1000

y = 1000/10

y = 10

Therefore, russell

Which is a graph of a proportional relationship?

Answers

The form of the equation of a proportional relation is y = kx, where k is the constant of proportionality.

A graph of a proportional relationship is a straight line that passes through the origin.

The constant of a proportionality in a graph of a proportional relationship is the constant ratio of y to x (the slope of the line).

Answer:

The one on the bottom left.

Step-by-step explanation:

The graph of a proportional relationship is a line that goes up at a constant rate and goes through the origin.

Since it is connected to the origin it's proportional

notice how none of the others are connected to the origin

It needs to be a straight line

So, x and y have a proportional relationship.
