Answer:

Step-by-step explanation:

an angle is 22 degrees smaller than a second angle. the two angles are complementary. what is the measure of the smaller angle? ​

Answers

Let the first angle be x°.

Then the second angle shall be (x - 22)°.

The two angles are complementary. Hence their sum shall be 90°.

First angle + second angle = 90°

=> x° + x° - 22° = 90°

=> 2x° = 112°

=> x° = 56°

Hence first angle = x° = 56°.

Second angle = (x - 22)° = 34°.

Slope intercept form of points 0, -4 and -1, 4

Answers

Answer:

[tex]y=\frac{0}{-1} -4[/tex]

Step-by-step explanation:

first, you have to find the slope, and to do that you use this equation [tex]\frac{y2-y1}{x2-x1}[/tex]

     so, now to insert your points (0,-4), (-1,4)

                                                      (x1,y1)  (x2,y2)

[tex]\frac{4-4}{-1-0} = \frac{0}{-1}[/tex]

now that you have the slope you can find the y-intercept of the slope-intercept form by looking at your first point (0,-4) and get -4

- if you were to look at this point on a graph it would be on the y-axis therefore, -4 is the y-intercept [if you don't have a point like this one then you can look at a graph with one of your points and make a slope until you are on the y-axis :)]

therefore, the slope-intercept form is y=[tex]\frac{0}{-1}[/tex] -4

[ps, your slope is a zero slope :)]

Answer:

y = - 8x - 4

Step-by-step explanation:

y = mx + b

"m" is slope, "b" is y-intercept.

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

~~~~~~~~~~~~~~~

(0, - 4) are coordinates of y-intercept.

( - 1, 4)

m = [tex]\frac{4 + 4}{-1-0}[/tex] = - 8

y = - 8x - 4

What is the area of the shaded sector?

A. 41π units^2
B. 8π units^2
C. 16π units^2
D. 20π units^2​

Answers

The area of the shaded sector of the circle is 16π units².

How to find the area of a circle?

Suppose the circle has radius of 'r' units, then, its area is given as:

[tex]A = \pi \times r^2[/tex]

sq. units

Since radius of a circle is half of its diameter, so if diameter is of 'd' length, then r= d/2, thus, area can be rewritten as:

[tex]\pi \times (\dfrac{d}{2})^2[/tex]

sq. units

We are given that;

θ = r radians

r = 4 units

Now,

To convert radians to degrees, we use the formula:

Degrees = Radians × 180°/π

So,

θ = r × 180°/π

Substituting these values in the formula for area of a sector, we get:

Area of a sector = (r × 180°/π / 360°) × π(4)²

Simplifying, we get:

Area of a sector = r² units²

=16π units².

Therefore, by the area of a circle the answer will be 16π units².
