F(x) = x^2 + 1 f(10)
f(10) = 10^2 + 1
f= 101
I think answer is 9.3 after it’s rounded
use the formula a^2 +b^2=c^2
Answer:
His average speed was of 10.42 m/s
Step-by-step explanation:
We use the following relation to solve this question:

In which v is the velocity(in m/s), d is the distance(in meters), and t is the time, in seconds.
