Answer:
89
Step-by-step explanation:
![3+75t-16t^{2} =h\\\\](https://tex.z-dn.net/?f=3%2B75t-16t%5E%7B2%7D%20%3Dh%5C%5C%5C%5C)
we evaluate when t=2
![3+75(2)-16(2)^2=h\\\\3+150-64=h\\\\h=89](https://tex.z-dn.net/?f=3%2B75%282%29-16%282%29%5E2%3Dh%5C%5C%5C%5C3%2B150-64%3Dh%5C%5C%5C%5Ch%3D89)
so it's 89 feet
Answer:
x=7
Step-by-step explanation:
9x+20x+16+12x+10+7x-2=360
48x+24=360
48x=360-24
48 x=336
x=336/48=7
Answer:
b. y = 3(x+2)^2 + 5
Step-by-step explanation:
The vertex form of a parabola is
y = a(x - h)^2 + k where (h, k) is the vertex.
Here h = -2 and k = 5 so the following could be the required equation\;
y = 3(x+2)^2 + 5
