Answer:
h = 64 feet
Step-by-step explanation:
If you graph the function you see that 64 feet is the maximum of the parabola so this is the max height that the projectile reaches.
Answer:
B
Step-by-step explanation:
1. Given mathematical statement

So,

2. Rewrite it as

So,

3. Combine like terms
and 

So,

4. Add
to both sides:

So,

5. Subtract 3 from both sides:

So,

6. Divide both sides by 5:

So,

The answer above is correct.
Answer:
x=-12
Step-by-step explanation:
AC=AB+BC
x+29=2x+33+8
x-2x=33+8-29
-x=12
x=-12
Answer:

Step-by-step explanation:
Given;
(a) y = tan (7t)
let u = 7t
y = tan(u)
du/dt = 7
dy/du = sec²(u)

(b)

let u = 4 - v²
du/dv = -2v
let v = 4 + v²
dv/du = 2v
