Answer: B. 49 1 hour
Step-by-step explanation: hope this helps
For resting your heart would beat 72 times per minute and for running your heart would beat 150 times per minute (and together it would be 222)
When doing this you would plug 6 in for every x giving you f(6)=(6-3)2+1
F(6)=(3)2+1
2•3= 6+1 =7
So your answer would be 7
Hope this helps
