I need help on the graphs

Answers

Answer 1

Answer:

y < 4

y > 2x - 4

y > -2x - 4

Step-by-step explanation:

For each line, figure out the equation, and then turn the = into a < or > depending on which side of the line you want to include.

Example, line B has equation y = 2x - 4, and you want to be above it, so y has to be larger than 2x - 4.

The second graph works the same way, try it.

Step-by-step explanation:

The graph is constant above and below the piece that is graphed. The graph is continuous, so we don't need to put any open or closed dots anywhere. (If you wanted, you could put closed dots at the ends of the piece shown--just to reinforce that the function is defined at those turning points.)

Answer

y= 3/2 x - 2

Step-by-step explanation:

so you have to find the slope which would be

m =

y2 - y1

x2 - x1

then you find you points that you are using (2, 1) and (0, -2)

when you plug it in it is

-2-1

0-2

you simplify the numbers and get rid of the negatives to get m=3/2 x

then your y intercept is where your line meets the y axis or wherever x=0

so your y intercept is (0, -2) so the b = -2

What is volume of thi shown below?

Answers

Answer:

13613.46 cm^3

Step-by-step explanation:

Height of the conical top= 25 cm

Diameter of the conical top = 20 cm

Radius of the conical top = 10 cm

[tex]We\ know\ that,\\Volume\ of\ a\ cone\ = \frac{1}{3}\pi r^2h\\Hence,\\Volume\ of\ the\ conical\ top\ = \frac{1}{3}\pi 10^2*25 = \frac{1}{3} \pi 100*25\\= 833.3\pi\ cm^3[/tex]

Height of the cylindrical base = 35 cm

Diameter of the cylindrical base = 20 cm

Radius of the cylindrical base = 10 cm

[tex]We\ know\ that\ ,\\Volume\ of\ a\ cylinder\ = \pi r^2h\\Hence,\\Volume\ of\ the\ cylindrical\ base = \pi* 10*10*35\\=3500\pi\ cm^3[/tex]

[tex]Hence,\\Volume\ of\ the\ given\ figure\ = Volume\ of\ the\ conical\ top\ + Volume\ of\ the\ cylindrical\ base\ \\Hence,\\Volume\ of\ the\ given\ figure\ =833.3\pi +3500\pi \\=(3500+833.3)\pi \\=4333.3\pi \\=13613.46 cm^3[/tex]

Answer:

13,614cm³

Explanation:

There are 2 solid shapes in the object;

A cylinder and A cone

Volume of the cylinder = πr²h

Volume of the cone is 1/3πr³h

h of cone = 25cm

h of cylinder = 35cm

d of the cylinder and cone = 20cm

r = d/2 = 10cm

Volume of the cylinder = πr²h

= π(10)²×35 = 10,996cm³

Volume of the cone = 1/3πr²h

= 1/3π(10)²×25 = 2618cm³

Therefore the total volume of the object above =

Volume of the cylinder + Volume of the cone =

10,996cm³ + 2618cm³ = 13,614cm³

Brian and Emily are testing different paper airplane designs to see which will allow a plane to go the farthest. Emily folds her plane and attaches a paperclip to the front of it. After she throws the plane, it travels about fifty feet and then starts to fall to the ground. Why does the plane eventually fall to the ground?

The force of air resistance stops acting on the plane.

The plane was not designed to carry a load like a paperclip.

The force of gravity is greater than the force keeping the plane in the air.

The paperclip creates a magnetic force that attracts the plane to the ground.

and actually answer it, answers will be reported if you put random letters.

We add 25 and subtract 25 to complete the square.

[tex](x+5)^{2}-38=0\\[/tex] is the equation we get.

Step-by-step explanation:

[tex]x^{2} +10x-13=0\\x^{2} +10x+25-13-25=0\\(x+5)^{2}-38=0\\[/tex]

So, we're adding 25-25 to complete the square.
