Answer:
See the attachment. (All results are integers, so are correct to 6 decimal places.)
Step-by-step explanation:
The function simplifies to ...
... f(x) = x(x-9)/((x+1)(x-9))
... f(x) = x/(x+1) . . . for x ≠ 9
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:
Step-by-step explanation:do you have the answers to choose from?
There are 8 yellow and 24 blue. Our ratio from yellow to blue is 8:24.
To simplify this, we need to see if we can divide 8 and 24 by a common factor.
8 and 24 can be divided by 8, so let's do that.
8/8 = 1.
24/8 = 3.
Your new and simplified ratio is 1:3 from yellow to blue, but we're looking for blue to yellow. Flip the ratio.
3:1 is your ratio.
C.) is your correct answer.
I hope this helps!

5(2- 7x)
5×2 - 5×7x
= 10-35x
