Answer: When t = 4.25 R(t) = D(t)
This tells you that at 4.25 seconds into their flights, both the Rocket and the Drone were at a height of 20 feet.
Step-by-step explanation: The point where the two graphed lines cross is where the values are equal.
The Drone has been hovering at 20 feet between 2 and 5 seconds. The Rocket passed through that height for a brief (millisecond) time as it was falling back to the ground.
Without grid lines it is my best estimation (using a ruler to create a verticla line from the intersection of the lines to the time scale) that t = 4.25. It is between 4 and 4.5 seconds.
We need to find the direction the ball is moving, so wee have this parametric equation, namely:

The graph of this equation is given in figure below. So, we well substitute some values of t in the equation:
If t = 0x = 4 and y = 3
P0(4, 3)
if t = 1x = 3.08 and y = 5.52
P1(3.08, 5.52)
if t = 2x = 1.16 and y = 5.72
P2(1.16, 5.72)
So, as shown in the figure, the answer is

Answer:
Rational
Step-by-step explanation:
Write and solve an equation of ratios:
vinegar 0.25 x
------------ = --------- = -----------
dressing 1.00 2 cups
Cross multiply. We get 0.5=x. Sue needs to use 1/2 cup of vinegar and 1 1/2 cups of the other ingredient(s).
