Answer:
2√2
Step-by-step explanation:
r(t) = (2t, t²)
v(t) = dr/dt
v(t) = (2, 2t)
v(1) = (2, 2)
|v(1)| = √(2² + 2²)
|v(1)| = 2√2

so from the graph we see that at zero weeks (the start), he has 15 rocks.
each week he adds 5 rocks. (he is at 30 rocks after 3 weeks)
This narrows the choices down and D is our answer
Answer: 954
Step-by-step explanation:
In order to vertically stretch a function by a factor k, we have to multiply the function expression by k.
So, in order to stretch the function by a factor of 1/5, we simply have to multiply:

So, if we shrink the function -5x by a factor of 1/5, we get the function -x.
