1.
The range are y's. The y's in {(4,-1),(-7,2),(1,2),(2,1)} are -1,1,2 ⇒ A,B,C
2.
The domain are x's. The x's in {(4,-1),(-7,2),(1,2),(2,1)} are -7,1,2,4 ⇒ A,B,D
Answer:
(x-5) (x+4)
Step-by-step explanation:
x^2 - X-20
Factor
What two numbers multiply to -20 and add to -1
-5*4 = -20
-5+4 = -1
(x-5) (x+4)
Answer:
1). Mean: 14.2
Median: 13.5
Step-by-step explanation:
To calculate the mean, sum all values and divide by the number of values:
(13+16+14+17+13+12) / 6 ≈ 14.2
To calculate the median, order the values from small to large and take the middle value. If there is no middle. average the two values in the middle:
12,13,<u>13,14</u>,16,17
The median is (13+14)/2 = 13.5.
Using this explanation you should be able to find the rest.
Answer:
option a.

area of the circle= pi×r²
area of circle=pi×3²
area of circle=pi×9units²
Well, at the END of 100, none excluding post decimal zeroes, including them there are infinite. If you meant how many zeroes inside 100, 2 then.
