Answer: 120 beats per 45 seconds
Step-by-step explanation:
Using geometric sequence concepts, it is found that:
a) The rule is:
.
b) An exponential relationship exists between the two variables.
<h3>What is a geometric sequence?</h3>
A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:

In which
is the first term.
A geometric sequence represents an exponential relationship between the variables.
In this problem, considering that the first-place finisher wins half of $1.500.000 in total prize money, and each finisher earns half of the one who finished above, the first term and the common ratio are given by:
.
Hence the nth term of the sequence is given by:

Answer:
a. 56
b. 72
c. 64
Step-by-step explanation:
x=3y
Switch sides
3y=X
Divide 3 both sides to get
T= x/3
Since we can find that the graphs Y value is by a factor of 2 looking at the graph we can find
f(3)=8
