Marko's heart beats 72 times per minute during normal activity. It beats 65 times per minute during sleep, and 118 times per minute when Marko is exercising.
During a 24-hour period, Marko slept from 10:00 p. m. until 5:00 a. m. and then
exercised from 5:30 a. m. to 7:30 a. m. For the remaining time he had normal
activity. During that 24-hour period, how many times did Marko's heart beat?
(times)

105,540 beats

Step-by-step explanation:

10:00-5:00 is 7 hours long so

60(minutes)×7=420 minutes

since his heart beats 65 times/min.

420×65=27,300 beats

5:30-7:30 is 2 hours long so

60(minutes)×2=120 minutes

120×118=14,160 beats

7 hours+2 hours=9 hours

24-9=15 hours

60×15=900 minutes

900×72 beats=64,800 beats

Add all heart beats together

27,300+14,160+64,080=105,540

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
