Step-by-step explanation:
This can solved graphically, using algebraic manipulation or differential calculus.
Plotting the equation will generate a parabola. The vertex represents the point where the ball will reach the maximum height.
The vertex can be determined by completing the square
h = -16t2 + 45t + 5
h - 5 = -16(t2 - 45/16t)
h - 5 - 2025/64 = -16(t2 - 45/16t + 2025/1024)
(-1/16)(h - 2345/64) = (t - 45/32)^2
The vertex is
(45/32,2345/64) or (1.41,36.64)
The maximum height is 36.64 ft
Using calculus, taking the first derivative of the equation and equating to 0
dh/dt = 0 = -32t + 45
t = 45/32
Substituting this value to the equation
h = -16(45/32)^2 + 45(45/32) + 5
h = 36.64 ft

Answer:
<h3><em>
isosceles</em></h3>
An isosceles triangle is a triangle that has two sides of equal length.
An acute triangle is a triangle with three acute angles (less than 90°).
A scalene triangle has all its sides of different lengths. Equivalently, it has all angles of different measure.
An equilateral triangle is a triangle in which all three sides are equal.
Im not that sure but I think that the answer is 96+16x
The answer is 4 and 5 my dude ( 16 and 25)
