We have that
[3/2,3/8,3/32,3/128,3/512]
the sum of the geometric sequence is [3/2+3/8+3/32+3/128+3/512]
=(1/512)*[256*3+64*3+16*3+4*3]
=(3/512)*[256+64+16+4]
=(3/512)*[340]
=(1020/512)
=255/128---------> 1.9922
the answer is
1.9922
another way to calculate it
<span>is through the following formula
</span>∑=ao*[(1-r<span>^n)/(1-r)]
</span>
where
ao---------> is the first term
r----------> is the common ratio<span> between terms
n----------> </span><span>is the number of terms
ao=1.5
r=1/4-----> 0.25
n=5
so
</span>∑=1.5*[(1-0.25^5)/(1-0.25)]-------------> 1.99
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:
3
Step-by-step explanation:


Since he sold for 6 hours over the course of 3 days. Convert that to 18 hours total selling time. divide the amount sold by the hours and there is your answer.
