h(t) =-16t^2 + 80t + 4,\quad 0 \le t \le 5.04

(a) Find the height of the ball (in feet) above the ground 2 s after its released.

That's just h(2)

h(2) = -16(2²) + 80(2) + 4 = -64 + 160 + 4 = 100

Answer: 100 feet

(b) Find the height of the ball (in feet) above the ground 4 s after its released.

That's just h(4)

h(4) = -16(4²) + 80(4) + 4 = -256 + 320 + 4 = 68

Answer: 68 feet

Yes there is an error in this statement.

because x^2 = 25 
so x = 5...this is one condition

Another condition is x = -5
(-5)^2 = 25 (this is also true)

The perimeter of a triangle is 53 feet. One side of the triangle is 12 feet shorter than the second side. The third side is is 4
grandymaker [24]

Let the shortest side be = a, then side b = 2·a and side c = (b + 24)

We are given that a + b + c = 84

Substituting for b and c

a + 2·a + (a + 24) = 84

4·a + 24 = 84

4·a = 84 - 24 = 60

a = 60/4 = 15 feet

b = 2·15 = 30 feet

c = 15 + 24 = 39 feet


sorry if i am wrong
