Answer:

Step-by-step explanation:

First find the slope: 1-4/5-(-2)= -3/7

Then you put it into this formula with any one of the points:

y-y1= m(x-x1)

Y-(1)= -3/7(x-5)

Y-1= -3/7x + 2.14

Y= -3/7x + 3.14

Answer:

The only thing I can think of is the slope intercept form.

The slope of -2,4 and 5,1 is -3/7

The Y intercept is 22/7

$y=-\frac{3}{7}x+\frac{22}{7}$

Answer:

My earlier answer was deleted, so I'm reposting. The only thing I can think happened is that I included a link to a free bar chart program, which I used for the attached chart.

Step-by-step explanation:

Make your own chart or find an online bar chart utility. I was unable to properly label the title and axes on my chart, so modify these properties.

"What impact can a very large volcanic eruption have on earth's climate?" 1. It will warm the earth's surface as more lava is re

Ludmilka [50]

The impact of a very large volcanic eruption that have an effect on earth's climate is It will cool the earth's surface as radiation from the sun is blocked from entering the atmosphere.

Explanation:

A very large volcanic eruption will spew tonnes of fine dust particles (pyroclast) into the atmosphere. These particles will be spread over large area by wind and the particles will remain suspended in the air for longer periods before they settle on the earth's surface.

The suspended particles will block the sun, and by reflecting most of the sunlight before it reaches the earth’s surface, will cause the surface temperatures to drop.

This same phenomenon caused the demise of dinosaurs after a meteorite strike threw dust particles into the atmosphere that lingered for a long time smothering plant life too.

Two ropes are attached to a large ballon in a parade. The people holding the ropes are 40 feet apart,and the angle between the t

qaws [65]

Ropes are 9.63 meters ans 8.178 meters.

Step-by-step explanation:

Step 1 :

List all the given things

Distance between people holding ropes = 40 =(40*0.3048) meters = 12.192 meters

Angle between two ropes = 86 degrees

Angle of elevation of one rope = 42 degrees

Step 2 :

Two angles of triangle are already given so third angle can be calculated as -

Third angle = 180 - ( 86 + 42 ) = 52 degrees

Step 3 :

As we know all three angles we will apply sine rule now, which is

$\frac{a}{sine A} = \frac{b}{sine B} = \frac{c}{sine C}$

Step 4 :

By putting values, we have

$\frac{a}{sine 52} = \frac{b}{sine 42} = \frac{12.192}{sine 86}$

Step 5 : Calculating a and b

$a = 12.192 * \frac{sine 52}{sine 86}$ , $b = 12.192 * \frac{sine 42}{sine 86}$

Step 6 :

By putting values of all sine and calculating we get,

a = 9.63 meters and b = 8.178 meters

Veronica has 7 yards of ribbon. Each bow requires 3/4 of a yard ribbon. How many bows will she be able to make with the ribbon s

Sonbull [250]

Answer && Step-by-step explanation:

7 yards == 4/4

by simple arithmetic remove 3/4 from 7 until you can no longer obtain 3/4 from it

7 => 6*1/4

6*1/4=>5*2/4

5*2/4=>4*3/4

4*3/4=>4

4=> 3*1/4

3*1/4=>2*2/4

2*2/4=>1*3/4

1*3/4=>1

1=>1/4

1/4 remains and 9 bows were made
