Answer:
![a(t) =n(0.25t^2)](https://tex.z-dn.net/?f=a%28t%29%20%3Dn%280.25t%5E2%29)
Step-by-step explanation:
Given
Required
Determine the area in terms of time
From the question, we have:
-> radius per time
and
--> area from radius
The interpretation of the question is to find the composite function: a(t)
If
, and
, the
Substitute 0.5t for r
![a(t) =n(0.5t)^2](https://tex.z-dn.net/?f=a%28t%29%20%3Dn%280.5t%29%5E2)
![a(t) =n*0.25t^2](https://tex.z-dn.net/?f=a%28t%29%20%3Dn%2A0.25t%5E2)
![a(t) =n(0.25t^2)](https://tex.z-dn.net/?f=a%28t%29%20%3Dn%280.25t%5E2%29)
The mean of the numbers is c. 67
Answer:
Your first instinct might be to go ahead and add the x terms together, BUT this would be a bad thing to do! You cannot combine the x2 and 2x, because the first term has an exponent (2) and the second one does not have an exponent; therefore, you cannot add them together!
