Answer:

x=3

Step-by-step explanation:

4(x-3)=?

distribute: 4x-12=?

Add 12 on both sides to leave 4x on one side: 4x-12+12=12

4x=12

now isolate the variable by dividing 4 on each side: 4x/4=12/4

x=3

Answer:

C

Step-by-step explanation:

The length of arc AC (L) is calculated as

L = circumference of circle × fraction of circle

  = 2πr × \frac{150}{360}

  = 2π × 12 × \frac{5}{12}

 = 2π × 5

 = 10π ≈ 31.42 → C

What is the midpoint of the line segment with endpoints
sertanlavr [38]

Answer:

Midpoint

Step-by-step explanation:

The midpoint is the point on the segment halfway between the endpoints. It may be the case that the midpoint of a segment can be found simply by counting. If the segment is horizontal or vertical, you can find the midpoint by dividing the length of the segment by 2 and counting that value from either of the endpoints.

The ratio of two complementary angles is 5 to 1. what are the angles?
densk [106]
Call x and y those angles. If they are complementary, then their sum equals 90°:

x + y = 90°

y = 90° - x

The ratio of them is 5 to 1. So,

x/y = 5/1

x/(90° - x) = 5/1

x = 5 * (90° - x)

x = 450° - 5x

x + 5x = 450°

6x = 450°

x = 450°/6

x = 75°

The measure of the other angle is

y = 90° - 75°

y = 15°

The angles are 75° and 15°.

I hope it helps. =)

Write an equation of the form y=a sin bx or y= a cos bx to describe the graph below.
kakasveta [241]

we conclude that the graphed equation is:

y = 4*cos(pi*x)

<h3></h3><h3>Which trigonometric equation is the one in the graph?</h3>

First, we can see that the graphed function is even, so we know that it wiill be a cosine.

We also can see that the maximum is 4 and the minimum is -4, so the amplitude is 4.

Then we have something like:

y = 4*cos(b*x)

To find the value of b, we can use the fact that the zeros of the function are at x = ±1/2

Then:

b*1/2 = pi/2

b = pi

Finally, we conclude that the graphed equation is:

y = 4*cos(pi*x)
