What is the equation of this line in slope-intercept form?

Mathematics
1 answer:
Usimov [2.4K]3 years ago
5 0

Answer:

B

Step-by-step explanation:

Reminder: slope-intercept form is y=mx+b where m is the slope and b is the y intercept

There are two points given on the line: (-1, 2) and (1, -4)

First, find the slope

Reminder: slope is y2-y1/x2-x1

Substituting the numbers into the equation gives -4-(-2)/1-(-1) which would make m=-3

Now that the slope is found, we can use slope point form

Reminder: slope point form is y-y1=m(x-x1)

Substituting the numbers would give this equation:

y-2=-3(x-(-1))

Simplifying the equation would give y=-3x-1.

Find the perimeter of this shape<br>​
Margaret [11]
The answer is 257.08m. Explanation: you know that one side of the square in the middle is 50m. This is the same as the diameter of one of the half circles on each side. The perimeter of a circle is the formula C=2(pi)r, where r is the radius. Dividing 50 by two will get you the size of the radius, then just plug it into the equation to find the perimeter of both rounded sides (a full circle). The two circular sides equal 157.08m, so then you just need to add the flat sides, which are both 50m since they’re congruent. 157.08m + 50m + 50m = 257.08m, so the perimeter of the shape is 257.08m.

Find the fourth roots of 256(cos 240° + i sin 240°).
Mashcka [7]

Answer with Step-by-step explanation:

We are given that

We have to find the fourth roots of given complex number.

(256)^{\frac{1}{4}}=(4^4)^{\frac{1}{4}}=4^^{\frac{1}{4}\times 4}=4

By using the formula

(a^b)^x=a^{bx}

\theta=240^{\circ}

\theta=\frac{240}{4}=60^{\circ}

Angle of rotation=\frac{360}{4}=90^{\circ}

Therefore, the four roots of given complex number are

4(cos 60^{\circ}+i sin60^{\circ})

4(cos150^{\circ}+i sin150^{\circ})

4(cos240^{\circ}+isin 240^{\circ})

4(cos330^{\circ}+i sin330^{\circ})

If the scale factor of two similar cylinders is 4:7, what is the volume ratio?
jekas [21]

Answer:

     64 : 343

Step-by-step explanation:

When working with scale factors

Lengths are related by the scale factor

perimeters are related by the scale factor

areas are related by the scale factor squared

volumes are related by the scale factor cubed

The scale factor is 4:7

The volumes are related by 4^3 : 7^3

                                             64 : 343

nikitadnepr [17]

Answer:

The answer should be 45

Step-by-step explanation:

To get the whole are you would have to multiply the lenght with the Width and then take that answer and multiply it with the height

<u>BUT</u>

because you want the surface area, it would be just the lenght and width

15x3=45

so 45 is your answer.
