Volume=6,925.5 pi
V= pi r^2 h
V= pi 13.5^2 (38)
V= pi 182.25 (38)
V= 6,925.5 pi
Sa=1390.5 pi
La= 2 pi r h
2 pi 13.5 (38)
2 pi 513
1026 pi
Sa= la+2 pi r^2
1026 pi + 2 pi 13.5^2
1026 pi + 364.5 pi
1390.5 pi

Which equation represents the line that is parallel to segment RS in the triangle below and passes through point T?

mestny [16]

Answer:

$y = \frac{1}{2}x +4$

Step-by-step explanation:

Given:

$R = (0,0)$

$S= (8,4)$

$T = (-2,3)$

First, we have that the line is parallel to RS.

This means that the line has the same slope as RS and the slope of RS is calculated as follows:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{4-0}{8-0}$

$m = \frac{4}{8}$

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

So, the line has a slope of $m = \frac{1}{2}$

Next, we have that the line passes through $T = (-2,3)$ .

The equation of the line is then calculated using the following formula

$y - y_1 = m(x - x_1)$

$y - 3 = \frac{1}{2}(x - (-2))$

$y - 3 = \frac{1}{2}(x +2)$

Open bracket

$y - 3 = \frac{1}{2}x +1$

Make y the subject

$y = \frac{1}{2}x +1+3$

$y = \frac{1}{2}x +4$

What is the answer?????

Step 1. Remember apples with apples, oranges with organges.

What's 75? people, and 2? Cakes

So 75/2 = 150/x, not the other way around

Calculate the distance between the points M=(-1, -2) and C=(-9, 2) in the coordinate plane.

Ivanshal [37]

Answer:

nearest hundredth 8.944

Step-by-step explanation:

d = √((x2-x1)2 + (y2-y1)2)

Step by step procedure:

Find the difference between coordinates:

(x2-x1) = (-9 - -1) = -8

(y2-y1) = (2 - -2) = 4

Square the results and sum them up:

(-8)2 + (4)2 = 64 + 16 = 80

Now Find the square root and that's your result:

Exact solution: √80 = 4√5

Approximate solution: 8.944
