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

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

$B_{30}=1.433B$

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

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

Compare the average score of a student at the beginning of a month and at the end of that month, if at first, it increased by 40

IceJOKER [234]

Answer:

Increased by 5%

Step-by-step explanation:

Let at the beginning the student's score be $s$ points.

At first, it increased by 40%. So, the new score is

$s+0.4s=1.4s$

Then it decreased by 25%, so the new score is

$1/4s-0.25\cdot 1.4s=1.4s-0.35s=1.05s$

At the beginning of a month the score was $s$ and at the end of that month the score was $1.05s$ . Since $1.05>1,$ the score increased by $1.05-1=0.05=5\%$
