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: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
