Answer:
Step-by-step explanation:
<u>Instantaneous Velocity</u>
Given r(t) as the vector function of the position for time t, the instantaneous velocity is computed as:
We are given:
Thus:
Computing the derivative:
Evaluating for t=π/4:
To find the average of a group of numbers you add them all up and divide by how many there are.
2+3+6+8+4=23
23/5=4.6
so your average is 4.6
So I dont have all the answers but I hope this helps:
a) (5,4) and (6,3)
b) (1,3), (2,4), (5,7), (6,8)
Im stuck in the last question, but I hope this helped you
