We need to find the direction the ball is moving, so wee have this parametric equation, namely:

Note that this parametric equation is an ellipse. The graph of this equation is given in figure below. So, we well substitute some values of t in the equation:
If t = 0
x = 4 and y = 3
P0(4, 3)
if t = 1
x = 3.08 and y = 5.52
P1(3.08, 5.52)
if t = 2
x = 1.16 and y = 5.72
P2(1.16, 5.72)
Finally, as shown in the figure, the answer is
B. counterclockwise. Notice the trajectory that follows P0, P1 and P2.
Answer:
C
Step-by-step explanation:
y》0.5x + 1.8
x = 4, y = 4.5
4.5》0.5(4) + 1.8
4.5》3.8 (true)
Answer:
= 16
Step-by-step explanation:
= 8 \div 2 . 4
= 16
