Dr/dt= 8cmM-¹
dA/dt = ?
but A= πr²
so dA/dr =2πr
but recall
dA/dt = dA/dr • dr/dt
dA/dt = 2πr • 8cmM-¹
dA/dt = 2×π×39 ×8 = 624cm²M-1
4 people email 3 more people each so 12 people are emailed, then these 12 people email 3 more people each, so 36 people are emailed.

Answer:

Step-by-step explanation:
The amplitude (A) and the mean (M) temperature are given by:

The mean temperature, 45 degrees. occurs at midnight (t=0) and the frequency is f=24h. Therefore, the temperature D, in degrees, as a function of t, in hours, is:
