Answer:
Option (G)
Step-by-step explanation:
Volume of the real cane = 96 in³
Volume of the model of a can = 12 in³
Volume scale factor = 
= 
Scale factor of the model = ![\sqrt[3]{\text{Volume scale factor}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Ctext%7BVolume%20scale%20factor%7D%7D)
![=\sqrt[3]{\frac{1}{8}}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B1%7D%7B8%7D%7D)
Therefore, scale factor of the model of a can = 
≈ 1 : 2
Option (G) will be the correct option.
Answer:
t = 2secs
Step-by-step explanation:
Given the height above the surface expressed as h = -16t^2 + 64 t + 80.
The velocity of the rocket at its maximum height is zero. Hence;
v(t) = dy/dt = 0
dy/dt = -32t + 64
0 = -32t + 64
32t = 64
t = 64/32
t = 2secs
Hence the rocket will hit the lake after 2 secs
No solution
Because 3 unknown needs 3 equation at least
Find the perpendicular line then find the intersection then find the point
perpendicular lines have slopes that are perpendicular
the slopes multiply bo -1
y=mx+b
m=slope
y=2x-3
2 is slope
2 times what=-1
what=-1/2
the equation is
y-3=-1/2(x-8) or
y=(-1/2)x+7
find intersection
