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
0.45 is equal to 45/100.
Simplify: 45/5=9; 100/5=20
The answer is 9/20, which is the third choice.
Hope this helped☺☺
Answer:
(A.) - <em>The y-intercept is 3, and the slope is 1/3</em>
Step-by-step explanation:
Answer:
f(x) = 6 x^2 - 1
f(2) = 6 * 2^2 - 1 = 23
f(-1) = 6 * -1^2 - 1 = 6 * 1 - 1 = 5
f(2) - f(-1) = 23 - 5 = 18
