Area of shaded region is 18π square unit.

<u>Step-by-step explanation:</u>

Given :- A circle with center O and radius 9 cm

To Find :- area of shaded region that is area of ABC

Solution : - BC = 9 cm

∠ABC = 80° = Ф

so, area of sector = πr²Ф / 360°

= (π×9×9×80) /360°

= 18π square unit

hence, area of shaded region is 18π square unit

Which equation shows a proportional relationship between x and y?
Ad libitum [116K]

Answer:

D. y=4x

Step-by-step explanation:

It asks for a proportional relationship between x and y

And is the only answer

because

When x and y is 1 the answer is

4/1

And when x and y is 2 the answer is

8/2

If you divide both of them are still 4

And this will always be the result no matter how many times you do it

like if you put it as 150

150 times 4 is 600/150

600 divided by 150 is 4

Hope this helps!

Please help me because I don't understand how to do it.:)
shutvik [7]

Answer:

y= 1/3 x +5

Step-by-step explanation:

To find the slope, we take two points

(0,5)   and (15,10)

The slope is found by the formula

m = (y2-y1)/ (x2-x1)

   = (10-5)/(15-0)

   = 5/15

   = 1/3

The slope is 1/3

The y intercept is found when x=0

When x=0  y=5

The slope intercept form of the line is

y=mx+b  where m is the slope and b is the y intercept

y= 1/3 x +5
