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:
B. $62
Step-by-step explanation:
y = mx + b
y = $10.50x + $10
The project will take five weeks so
y = $10.50(5) + $10
y = $52.50 + $10
y = $62.50
