50(2) -2(20) +6 = ?
100 - 40 + 6 = ?
60 + 6 = ?
66
Looking at the graph closely we can see that the heart rate increases from 0 to 6 min then became steady from 6 to 25 min then finally decreases from 25 to 30 min. Therefore the correct answer is:
“The heart rate increases for 6 minutes, remains constant for 19 minutes, and then gradually decreases for 5 minutes.”
In real life cardiac exercises, we can interpret that the period from 0 to 6 min is the period where the person is still warming up thus leading to an increase in heart rate. At 6 min, the person is fully warmed up hence reaching a stable heart rate. Then at 25 min, the person starts cooling down which means that the exercise is ending soon.
Answer:
x^-13
Step-by-step explanation:
Answer:
first part: y=2.63x
second part: y=2.08x
Step-by-step explanation:
1) 7.90 / 3 = 2.633333 (I rounded to 2.63)
2) 18.70 / 9 = 2.07777 (I rounded to 2.08)
I hope this what you were asking
