Step-by-step explanation:
i had the same question and got it wrong and it showed me the correct answer so basically

Answer:
my mother was 16 yrs old when I was born in 2005
Answer:
12 inches in height
Step-by-step explanation:
The formula for finding the area of a triangle is the height times the base then divide by 2
Hi!
h(t)= -16t^2+16t+90
h(t) = -16(t^2 - t) + 90
h(t) = -16(t^2 - t + (1/2)^2) + 90 + 4
h(t) = -16(t - 1/2)^2 + 94
vertex at(1/2 , 94) , since a = -16 < 0 , the parabola opens down, which makes the vertex. the global maximum, so:
Max at(1/2 , 94)
object hits the ground at h = 0, then:
-16(t - 1/2)^2 + 94 = 0
(t - 1/2)^2 = 94/16 = 47/8
t - 1/2 = ± √(47/8)
t = 1/2 ± √(47/8)
t = -1.9 , 2.9 => reject t = -1.9
t = 2.9 sec => time it takes for the projectile to hit the ground
