DENIUS [597]
If the linear functions have the same slope but different y-intercepts, they will never intercept. If the If the linear functions have the same slope and the same y-intercet, they are the same line. If the linear functions have different slopes and different y-intercepts, they will intercept.

A cylinder and a cone have the same volume. the cylinder has a radius x and height y. the cone has a radius of 1/2 x. find the h
vovikov84 [41]

Answer:

12 y

Step-by-step explanation:

π. x².y = ⅓. π (½x) ².h

=> eliminate π,

x²y = ⅓. ¼x².h

=> eliminate x²,

y = 1/12 h

h = 12 y

so, height of the cone = 12 y

Is quadrilateral jklm the result of a dilation of quadrilateral abcd by a scale factor of 2? why or why not?
4vir4ik [10]

No. Because sides JM and KL have different slopes from sides AD and BC .

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

For AD:

We have the points A(2, -2) and D(1, -4). Substitute:

m=\dfrac{-4-(-2)}{1-2}=\dfrac{-2}{-1}=2

For JM:

We have the points J(4, -4) and M(2, -9). Substitute:

m=\dfrac{-9-(-4)}{2-4}=\dfrac{-5}{-2}=2.5

2\neq2.5

----------------------------------------

Another argument.

No. Because the MJ is not twice as long as AD.

The formula of the length of a segment:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The length of AD:

|AD|=\sqrt{(1-2)^2+(-4-(-2))^2}=\sqrt{(-1)^2+(-2)^2}=\sqrt{1+4}=\sqrt5

The length of MJ:

|MJ|=\sqrt{(2-4)^2+(-9-(-4))^2}=\sqrt{(-2)^2+(-5)^2}=\sqrt{4+25}=\sqrt{29}

\sqrt{29}\neq2\sqrt5
