Answer:
21.75 cm/s
Step-by-step explanation:
1 cm above central position means D = 1, so we plug in 1 into D(t) and find the time and which this occurs.

This is the time at which this occurs.
To find instantaneous rate of change, we differentiate D(t) and plug in this t we found. Remembering that d/dt (Sin t) = Cos t

Now putting t:

Thus, the instantaneous rate would be around 21.75 cm/s

Answer:
1/2
Step-by-step explanation:
Every time clock moves 1 (like for example it move from 3 to 4) 1/8 it covers
3->4->5->6->7 => 1/8+1/8+1/8+1/8 => 4/8 => 1/2
Answer: C
Step-by-step explanation:
Okay so I had to round each of these numbers to the nearest tenth so hope that doesn’t mess up anything. What I got was e^4 = 54.6, 23 = 23,e^2 = 7.4, 3e = 8.2, e^e = 15.2 hope these help.
