Answer:
C
Step-by-step explanation:
H(t) = 47t - 0.83t^2
Vo = 47m/s
V (t) = 47 - 1.66 t
a) t = 8 s; V(8) = 47 - 1.66(8) = 33.72 m/s
b) t = a; V(a) = 47 -1.66(a)
c) Hit the moon t =?
h(t) = 0 => 47t - 0.83 t^2 = 0
Factor: t (47 - 0.83t) = 0
47 - 0.83t = 0 => 0.83t = 47
t = 47 / 0.83 = 56.63 s
d) Velocity when hit the moon
The velocity of the arrow when it hits the moon is the same initial speed with opposite sign.
V = - 47 m/s

Answer:
1/5
Step-by-step explanation:
The length and width of rectangle Z would be 4 inches as the width and 4 inches as the length. This is because first, you combine and find the total perimeter of Rectangle Y. The perimeter of rectangle y would be P=length + length + width + width, which is 16 inches. Rectangle Z has the same perimeter total as rectangle Y and rectangle Zs area is the same as rectangle Y. 4x4 is equal to 16 while to find the perimeter, 4+4+4+4 is also 16.
