Which of the following shows - 49 simplified and written as a complex number?

Answer:

Arc Length = 65.9 ft

Step-by-step explanation:

Arc Length = 2π(r) * Central Angle/360

=> Arc Length = 2π(14) * 270/360

=> Arc Length = 87.96 * 0.75

=> Arc Length = 65.9 ft

Hope this helps!

Thx for unfriending me btw :)

Answer:

I think it's 45 degrees

Step-by-step explanation:

<c is 90 degrees and the interior of every triangle is 180 degrees so then we subtract 90 from 180 which is 90 so we divide 90 by two since b and a seem to be equal which is 45 degrees.

Graph it and you will see it is a function and since you are adding them it is also a relation. Good luck.

Answer:

it represents both a relation and a function.

Answer:

Step-by-step explanation:

2x - 2 = - 200

Bringing like terms on one side

2x = - 200 + 2 = - 198

2x = - 198

x = - 198/2 = - 99

==============================================================

Explanation:

We have a pair of vertical angles. The angles do not need to align vertically to be considered vertical angles. They simply just need to be opposite one another in this X configuration as the diagram shows.

Vertical angles are always congruent.

Set the expressions equal to one another. Solve for x.

2x+15 = 145

2x = 145-15 ... subtracting 15 from both sides

2x = 130

x = 130/2 .... dividing both sides by 2

x = 65

Answer: 65

Step-by-step explanation:

2x + 15 = 145

2x + 15 - 15 = 145 - 15

2x = 130

2x/2 = 130/2

x = 65

Answer:

Maybe True

Step-by-step explanation:

Hence, to find the area of a triangle, we need to know the base (b) and height (h) of it. This formula is applicable to all types of triangles, whether it is scalene, isosceles or equilateral.

Answer:

2. The formula below, the legs of the triangle are a and b. The hypotenuse is c.

True

Answer:

y = 7/6x - 0.75

Step-by-step explanation:

To get the slope, you do rise/run. This means that to get from one point to the other, you would go 7 units up and 6 units to the right. Then the y intercept is where you start on the y-axis, which is -0.75.

Hope this helps!!

Answer:

y = 7/6x - 2/3

Step-by-step explanation:

Hi,

To begin, pick two points from the graph. Doesn't matter what you pick as long as they're two different ones. So let's choose...

(4,4) and (-2,-3)

To find y = mx + b, we have to start with the slope (m). To find the slope, we find the change in y over the change in x.

-3 - 4 = -7 (the change in y)

-2 - 4 = -6 (the change in x)

So the slope is -7/-6 which equals 7/6.

Now, we plug that into y = mx + b

y = 7/6x + b

To find the b value, we plug in a point and solve for b.

4 = 7/6 (4) + b

4 = 28/6 + b

Simplify the 28/6 so it's easier to solve...

4 = 14/3 + b

-2/3 = b

So your equation is y = 7/6x - 2/3

I hope this helps :)

Answer:

x=52

Step-by-step explanation:

vertical angles are congruent so that means the angle measures are the same

so, you can set up this equation:

156=3x

and solve as follows:

156=3x

/3     /3

52=x

To prove that x=52 you can input 52 as x in the equation

156=3(52)

156=156

:) I hope this helps :)

Answer:

2x+23

Step-by-step explanation:

Answer:

39

Step-by-step explanation:

To find the perimeter you need to first find x. Because all of the angles are equal all of the sides must be equal too.

2x-3=x+5

x=8

2(8)-3+8+5+21-8

16-3=13+8=21+5=26+21=47-8=39

Answer:

$70 is the regular price of the shirt.

Step-by-step explanation:

One way in which to find the regular price here is to write the equation

0.60s = $42.  A 40% discount is reflected in 100% - 40%, or 1.00 - 0.40, which comes out to 0.60.

If 0.60s = $42, then the regular price of the shirt is

s = ($42)/0.60 = $70

Answer:

$70.00

Answer:

(9x, 9y) dilation

Step-by-step explanation:

(9, 9y) is the answer because F is 180 degrees rotations, G is not real, H is translations, and J is dilations and dilations is multiplying which makes the transformation non congruent.

Answer:

10 units

Step-by-step explanation:

I can faintly make out the grids in the image, but every line segment per grid is 1 unit, count them up and you get a total of 10 of them. Since I don't know what unit you need them in, they are set as 10 units.
