Caroline resting heart is 52 beats per minute (bpm). When she starts running her heart rate increases 1.25% each second until it

horsena [70]

Answer:74.55 beat per minute

Step-by-step explanation:

Given

Heart beat is 52 beat per minute

i.e. $B=\frac{52}{60}$ beat per sec

If heart rate is increases 1.25 % each sec

suppose B is the heart beat at first second therefore heat beat at 2 nd second

$B_2=B+1.25 \% B$

$B_2=B(1+1.25 \% )$

For 3 rd sec

$B_3=B(1+1.25\%)+1.25\%B(1+1.25\%)$

$B_3=B(1+1.25\%)^2$

similarly for 3 sec

$B_{30}=B(1+1.25\%)^{29}$

$B_{30}=1.433B$

$B_{30}=1.242\ \text{beat per second }$

$B_{30}=74.55\ \text{beat per minute}$

aksik [14]

Answer:

x = 8

<u>Solve for x:</u>

1/2 (4x - 8) + 3x = 36
2x - 4 + 3x = 36
5x - 4 = 36
