Find the coordinates of the midpoint of the segment whose endpoints are given. W (-3, -7) and X (-8, -4)

1 answer:

3 0

Midpoint coordinates: x-coordinate: (-3+(-8))/2=-11/2
y-coordinate: (-7+(-4)/2=-11/2
So coordinates of the midpoint are: (-11/2, -11/2).

if the height of the cylinder with a radius of 12 cm and a height of 20 cm has the same volume as a cone with a radius of 8 cm.

Marrrta [24]

Answer:

$\large\boxed{H=135\ cm}$

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have the radius r = 12cm and the height H = 20cm. Substitute:

$V=\pi(12^2)(20)=\pi(144)(20)=2880\pi\ cm^3$

The formula of a volume of a cone:

$V=\dfrac{1}{3}\pi r^2H$

r - radius

H - height

We have the radius r = 8cm and the volume V = 2880πcm³. Substitute:

$\dfrac{1}{3}\pi(8^2)H=2880\pi\qquad\text{divide both sides by}\ \pi\\\\\dfrac{1}{3}(64)H=2880\qquad\text{multiply both sides by 3}\\\\64H=8640\qquad\text{divide both sides by 64}\\\\H=135\ cm$

Find the value of A that makes the following equation true for all values of x. (1/7)^x = A^-9x.

elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

(1/7)^(x)=A^(-9x)

(1/7)^(x)=(A^(-9))^x

A^(-9)=1/7

A=(1/7)^9
