Answer:
t = 1 s
Step-by-step explanation:
The function models the height of the ball after t seconds is given by :
We need to find how many seconds does it take for the ball to reach its maximum height.
For maximum height put dh/dt = 0
So,
32-32t = 0
t = 1
So, it will take 1 second to reach its maximum height.
Answer:
So we have .
Step-by-step explanation:
Ok so we are in quadrant 2, that means sine is positive while cosine is negative.
We are given .
So to find the opposite we will just use the Pythagorean Theorem.
This is the opposite side.
Now to find and
.
.
Some teachers do not like the radical on bottom so we will rationalize the denominator by multiplying the numerator and denominator by sqrt(5).
So .
And now .
So we have .
