* 4. A circle is divided into ten equal sectors.

Mathematics
1 answer:
Fiesta28 [93]2 years ago
7 0

Answer:

a. Find the measure of each central angle.

The central angle of a circle = 360 °

Now Pie is cut into 10 equal sectors

Angle of each sector is given by

Angle of sector = Total central angle/number of sectors

=  {360}^{0}  \div 10

=  {36}^{0}

Hence , the central angle of one slice of pie is 36°

b. If the diameter is 50 in., find the length of an arc of one of the sectors.

length of an arc of one of the sectors =

= \frac{1}{n}  \times 2\pi \times r

= \frac{1}{10}  \times 2\ \frac{22}{7}  \times 50

= 31.42 \: in

Find x-intercept and y-intercept then you can draw the graph.

For example, the first question.

y=-3x+2

To find the y-intercept, x = 0

So substitute x = 0 in the equation.

y=0+2\\y=2

[Note]: You don't need to find the y-intercept, because from, y=ax+b

a is slope and b is y-intercept, you know b then you know y-intercept. For example b = 2 then y-intercept is at 2.

To find the x-intercept, y = 0

-3x+2=0\\-3x=-2\\x=\frac{2}{3}

Therefore, y-intercept = 2 and x-intercept = 2/3

(Try do another problems, just do the same. When you want to find the y-intercept, just look at the value of b or substitute x = 0 and When you want to find the x-intercept, just substitute y = 0 then solve for x.)

Solve for g:<br> 2g = -14
sweet-ann [11.9K]

Answer:

g= -7

Step-by-step explanation:

Think about it like a blank.

2x__=-14

Traditionally, if -14 wasn't negative, we would just do 7.

But, it is negative, so we make the 7 negative.

Hope this helps!
