Point a would lie at the same point from the beginning.
EXPLANATION
say point a is x,y. Reflecting over the y axis makes it -x, y. Reflecting over the x axis makes it -x, -y. Finally rotating it 180 degrees would make it x,y, the same spot as in the beginning.
Answer: Option C is correct.
<h3><u>Part A</u></h3>
⇒ 4x = 20
⇒ x = 20/4
⇒ x = 5
<h3><u>Part B</u></h3>
⇒ x/2 = 8
⇒ x = 8(2)
⇒ x = 16
<h3><u>Part C</u></h3>
⇒ x + 8 = 3x
⇒ 3x - x = 8
⇒ 2x = 8
⇒ x = 4
<h3><u>Part D</u></h3>
⇒ x = (x + 5)/2
⇒ 2x = x + 5
⇒ 2x - x = 5
⇒ x = 5
Given
d(t) = 0.8t ^2
t= 5 secs
d(5) = 0.8(5)^2 = 0.8 * 25 = 20
t= 10 secs
d(10) = 0.8(10)^2 = 0.8 * 100 = 80
20 m / 5 secs = 4 meters per sec
80 m / 10 sec = 8 meters per sec
4 mps + 8 mps = 12 mps
12 mps / 2 = 6 mps
6 mps is the average speed of the rock between 5 and 10 sec after being dropped
Is X=5 true or false? the answer is that it is true
Answer:
i think its 4, 5 and 27....
