Answer:
a)
b)
c) term number 17 is the one that gives a value of 40
Step-by-step explanation:
a)
The sequence seems to be arithmetic, and with common difference d = 3.
Notice that when you add 3 units to the first term (-80, you get :
-8 + 3 = -5
and then -5 + 3 = -2 which is the third term.
Then, we can use the general form for the nth term of an arithmetic sequence to find its simplified form:
That in our case would give:
b)
Therefore, the term number 20 can be calculated from it:
c) in order to find which term renders 20, we use the general form we found in step a):
so term number 17 is the one that renders a value of 40
Answer:
The percent increase per year is 4%
Step-by-step explanation:
we have
This is a exponential function of the form
where
y represent the monthly rent at Lake View Apartments
x represent the number of years
a is the initial value (y-intercept)
b is the base
r is the rate or percent increase
The percent increase per year is the base of the exponential function decreased by 1.
so
In this problem we have
---> initial value
Therefore
The percent increase per year is 4%
