Answer:
After n years, 120,000(1 - 0.92ⁿ) units, will be in use.
Step-by-step explanation:
Given;
estimated annual sales, a = 9600 units
determine common ratio, r;

sum of the units in use after n years is calculated by applying sum of nth term;


Therefore, after n years, 120,000(1 - 0.92ⁿ) units, will be in use.
Answer:
B. 3 and 4
Step-by-step explanation:
In order to find the numbers between which √11 lies, let us first guess the nearest perfect squares to √11. These are 9 and 16. Where 9 comes just before 11 and 16 comes just after 11. Now we have to write all three of them in ascending order.
√9 , √11 , √16
also
√9= 3 and √16 = 4
and
√9 < √11 < √16
3 < √11 < 4
hence we can see that √11 must lies between 3 and 4
