Answer:
Step-by-step explanation:
Known facts:
- the ball dropped from a height of 64 feet
- function
First question:
- the ball hits the ground when h(t) = 0, thus we get the equation
So the ball hits the ground in 2s
Second question
- to find how long it takes the ball to fall 36 feet, we must set h(t) = 64 - 36 = 28
So the ball hits the ground in 1.5s
Hope that helps!
To solve for sin(-135), the reference angle will be obtained as follow:
sin(-135)
=-sin(135)
=-sin(180-135)
=-sin 45
hence
the reference angle θ=45°

Proof by contradiction is a form of proof that establishes the truth or the validity of a proposition, by showing that assuming the proposition to be false leads to a contradiction. I googled this so it may not be correct
