Answer:
t = 3 seconds
Step-by-step explanation:
Here h(t) = -16t^2 + 144.
When the quarter hits the ground, its height will be 0 feet. Letting h(t) = 0 results in -16t^2 + 144 = 0, or 16t^2 = 144, or
144
t^2 = ------------ = 36/4 = 9 seconds^2
16
Therefore, the time, t, required for the quarter to hit the ground is t = √9, or t = 3 seconds
Answer:
i am on this exact question and i am confused myself because it seems like the answer should be "180 degree rotation with a translation of 5 units to the right" but that is not an option :/ so my best guess is either A or D hope this helps at all

Answer:
10
Step-by-step explanation:
15.75-10-
Variable A - horizontal axis ⇒ x
Variable B - vertical axis ⇒ y
points (x, y)
A B
1) 2 , 2
2) 2 , 8
3) 4 , 3
4) 5 , 1
5) 6 , 3
6) 7 , 5
7) 8 , 6
8) 9 , 2
Mean of Variable A.
(2 + 2 + 4 + 5 + 6 + 7 + 8 + 9) ÷ 8 = 43 ÷ 8 = 5.375 OR 5.40
Mean is the average value of the data set. Add all the numbers in the data set and divide its sum by its count.
