Given yo = initial height the ball was thrown from.
Given vo = the initial velocity of the ball thrown
y = yo + (vo)t -16t^2 where t = time.
This is a parabola opening downward.
There is no y intercept as the ball is thrown upwards upwards not necessarily straight vertically.
The x-intercepts occur when the ball reaches the level the ball was thrown from or the ground.
[9tan(θ) * 9cot(θ)] / 9sec(θ)
First cancel out the 9's:
tan(θ)cot(θ)/sec(θ)
Recall the following trig identities:
tan = sin/cos
cot = cos/sin
sec = 1/cos
Thus, we can rewrite the expression as:
[ (Sin(θ)/cos(θ)) *(cos(θ)/sin(θ)) ] / (1/cos(θ))
In the numerator, the sine's and cosine's cancel each other out:
1 / (1/cos(θ))
which we can rewrite as cos(θ).
Answer:
When given a percentage of growth or decay, determined the growth/decay factor by adding or subtracting the percent, as a decimal, from 1. In general if r represents the growth or decay factor as a decimal then: b = 1 - r Decay Factor. b = 1 + r Growth Factor. A decay of 20% is a decay factor of 1 - 0.20 = 0.

12 Feet is the depth of the pond. I am just guessing but i think that is it.
