Current temperature = -2°C
Rise in temperature = 15°C
New temperature = (-2 + 15)°C = 13°C
Answer:
Average velocity of the function over the given interval
= 
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given function y = 3/x -2 ...(i)
The average velocity of the function over the given interval
Average velocity = 
= 
now integrating
= 
= 
= 
by using formulas
log a-log b = log(a/b)
on simplification , we get
= 
= 
Average velocity of the function over the given interval
= 
The rate of change of Pete's height from 3 to 5 years can be determined as,

Thus, the required rate of change from 3 to 5 years is 4 in/year.
