Graph the line y= -3x - 2

Mathematics

1 answer:

Answer:

The graph is attached below.

Step-by-step explanation:

Given the line equation

$y=\:-3x\:-\:2$

Comparing the line equation with the slope-intercept form

$y=mx+b$

where m is the slope, and b is the y-intercept

Here:

m = -3

b = -2

When

x = 0, then y = -2 ∵ y = -3x - 2 = -3(0) - 2 = -2

When

x = 1, then y = -5 ∵ y = -3x - 2 = -3(1) - 2 = -3 - 2 = -5

The graph is attached below.

What is the volume of a hemisphere with a radius of 26.7 m, rounded to the nearest tenth of a cubic meter?

attashe74 [19]

Answer:

$39,865.1m^3$

Step-by-step explanation:

a hemisphere is half a sphere.

And if the formula for the volume of a sphere is:

$V=\frac{4\pi r^3}{3}$

we must calculate the volume of the sphere and in the end divide by two to find the volume of the hemisphere.

Since the radius is:

$r=26.7m$

substituting this into the formula for volume:

$V=\frac{4\pi (26.7m)^3}{3} \\\\V=\frac{4(3.1416)(19,034.163m^3)}{3} \\\\V=79,730.12m^3$

this is the volume of the total sphere, thus the volume of a hemisphere is:

$\frac{V}{2}=\frac{79,730.12m^3}{2}\\ =39,865.06m^3$

rounding to the nearest tenth:

$39,865.1m^3$

$1.8:12.06=\dfrac{1.8}{12.06}=\dfrac{1.8\cdot100}{12.06\cdot100}=\dfrac{180}{1206}=\dfrac{180:6}{1206:6}=\dfrac{30}{201}=\dfrac{30:3}{201:3}=\dfrac{10}{67}$

What is JK? please explain/show your work on how you got your answer

Travka [436]

Answer:

JK = 20 m

Step-by-step explanation:

<em>A line segment that connects two midpoints of the sides of a triangle is called a midsegment.</em>
<em>A triangle midsegment is parallel to the third side of the triangle and is half of the length of the third side.</em>

Point J is midpoint of side HI as HJ = JI

Point K is midpoint of side GI as GK = KI

JK is midsegment as connects the midpoints of the sides

JK = 1/2HG as per property of midsegment

6x - 4 = 10x/2
6x - 4 = 5x
6x - 5x = 4
x = 4

JK = 6x - 4 = 6*4 - 4 = 24 - 4 = 20 m
