The rate at which his pulse is increasing after 3 minutes is 9.5 beats per minute
<h3>How to determine the beat rate after 3 minutes?</h3>
The given graph shows the curve and the tangent.
From tangent line, we have the following points:
(x,y) = (3,119) and (1,100)
The beat rate (m) at this point is:

So, we have:

Evaluate the differences

Evaluate the quotient
m = 9.5
Hence, the rate at which Sam's pulse is increasing after 3 minutes is 9.5 beats per minute

Answer:
The diameter is 6
Step-by-step explanation:
the radius is just half of the diameter so 2x3= 6
I would say A (7) but I’m not 100% sure.
X+5=18
first get rid of the 5
so X+5-5=18-5
which makes X=13
