For this case we have the following equation:

Where, we have the following variables:
x: time in seconds
y: speed in feet per seconds
For the initial velocity, we evaluate x = 0 in the given equation:

Therefore, the initial speed is 12 feet per second.
Answer:
The particle's initially velocity is 12.
Answer:
The answer is d because 10-3 is 7
Answer:
(30,60)
90mph
Step-by-step explanation:
Answer:
We have 12.4 - ( - 3.5 ) = 12.4 + 3.5 = 15.9 is the distance between 2 points.
