Answer:
A ≈ 113 in²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
= π × 6²
= 36π
= 36 × 3.14
= 113 in²
Answer:
n = 9
Step-by-step explanation:
Step 1: Write equation
-4(9n + 9) = -12(4n - 6)
Step 2: Solve for <em>n</em>
<u>Distribute:</u> -36n - 36 = -48n + 72
<u>Add 48n to both sides:</u> 12n - 36 = 72
<u>Add 36 to both sides:</u> 12n = 108
<u>Divide both sides by 12:</u> n = 9
Step 3: Check
<em>Plug in n to verify if it's a solution.</em>
-4(9(9) + 9) = -12(4(9) - 6)
-4(81 + 9) = -12(36 - 6)
-4(90) = -12(30)
-360 = -360
Answer:
B. 90 degrees
Step-by-step explanation:
The definition of supplementary is that they add up to 180 degrees. If the measure of angle A is 90 degrees, then angle B is 180-90 = 90 degrees.
Answer:
(81x+13)
Step-by-step explanation:
Answer:
7. 2|x+2|-1
8. (-2,-1)
10. y≥2
Step-by-step explanation:
7. a|x-h|+k
Vertical stretch by a factor of two, horizontal shift left two, vertical shift down one
8. (h,k)
10. It should be y, but otherwise you are good
