Answer:
The instantaneous velocity after eight seconds is 9 m/s
Step-by-step explanation:
Given as :
The ball shot upward with velocity of 15 m/s
The height of the ball after t sec is given as h(t) =
Now, The instantaneous velocity after 8 sec = 
Or, The instantaneous velocity =
or, The instantaneous velocity = 
Now at t = 8 sec
The instantaneous velocity = 5 + 4 = 9 m/s
Hence The instantaneous velocity of ball at t = 8 sec , is 9 m/s Answer
Answer:
t = 9/5

Answer:
A -4n^2-2n + 3
Step-by-step explanation:
let's simplify this by making h(n) = u
this means g(h(n)) = g(u)
u = h(n) = -2n^2 - n
g(h(n)) = g(u) = 2u + 3
now plug h(n)) in wherever there is u
2(-2n^2-n)+3
-4n^2-2n + 3
the real world situation for ratio 29 to 30 is that their are 29 boys to 30n girls meaning less number of boys to girls in the class
Answer:
x - 44 > 5x - 5 is the simplified version. hope this helps
