Jeffrey calculated the slope between two pairs of points. He found that the slope between -5, 6 and -3, 2 is -2. He also found t
Cerrena [4.2K]

Answer:

Jeffrey is correct

All of these points are on the same line because the slope between (-3,2) and( 0,-4), which are coordinates from each of the pairs above, is equal to -2

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

step 1

Find the slope between -5, 6 and -3, 2

substitute the values in the formula

m=\frac{2-6}{-3+5}

m=\frac{-4}{2}=-2

step 2

Find the slope between (-1, -2) and (0, -4)

substitute the values in the formula

m=\frac{-4+2}{0+1}

m=\frac{-2}{1}=-2

step 3

Find the slope between (-3, 2) and (0, -4)

substitute the values in the formula

m=\frac{-4-2}{0+3}

m=\frac{-6}{3}=-2

therefore

Jeffrey is correct

All of these points are on the same line because the slope between (-3,2) and( 0,-4), which are coordinates from each of the pairs above, is equal to -2

a+b=350 => a=350 - b

3a + 5b = 1450
3(350-b)+b=1450
1050-3b+5b=1450
2b=400
b=200

The volume of a cone is 200.96 cubic yards. What is the radius of the cone if the height is 12 yd? Use pi =3.14 and round your a
Naddika [18.5K]

Answer:

If I'm doing the problem correctly, the radius should be 4 yards.

Step-by-step explanation:

You work the problem backwards. Multiply 200.96 by 3, since it's a cone, so you're working with the volume of what a cylinder would be with the same dimensions. Then divide by the height (12 yd), then divide by pi. You should end up with 16, and 4 squared equals 16. Work the problem forwards from there to check.

4 squared is 16. 16 times 3.14 is 50.24. 50.24 times 12 is 602.88. 602.88 divided by 3 is 200.96.
