Step-by-step explanation:

Answer:
(a) dy/dt = 68 - 3.72t
(b) 64.28m/s
Step-by-step explanation:
Given y = 68t - 1.86t²
Average Speed is rate of chance of distance with respect to time. Written as dy/dt
To obtain dy/dt, we differentiate y with respect to t, doing that, we have
dy/dt = 68 - 2(1.86)t
= 68 - 3.72t
(a) dy/dt = 68 - 3.72t
(b) To estimate the speed when t = 1, we substitute t = 1 in dy/dt .
dy/dt at t = 1 is
68 - 3.72(1)
= 68 - 3.72
= 64.28
The speed at t = 1 is 64.28m/s
Answer:
See below.
Step-by-step explanation:
1) Please check the number of volume of steel. It should be 54,259.2

. Not 54,259.2 cm. Right?
2) If so,
First
The volume of single rod

The number of rods

24 photos in 8 minutes
24/8 = the number of photos per minute
24/8 = 3
3/1 is the number of photos/ minutes
3 photos per minute is your answer
hope this helps
