2 answers:
Answer:
The city population will first be below 48,000 in the year:
2022
Step-by-step explanation:
It is given that:
In 2010, a city population was 55,210
in 2011 the city population will be
(100-1.09)×55210/100=98.91×55210/100
= 0.9891×55210
in 2012 the city population will be
0.9891×0.9891×55210
we have to find number of years t such that
i.e. the thirteen years from 2010 we will have city population less than 48000
i.e. in the year 2022

Answer:
a) -3
b) 5
c) 7
d) 4
Step-by-step explanation:
We have the function
a) We need to find the coefficient of .
This means that we need to find out what number is alongside the in this equation. From the function, we can find that it is -3
b) Now we need to find the degree of . Recall that the degree refers to the highest power of x that is present. As
is the largest power, our degree would be 5.
c) The constant term refers to the number within the function that does not have any x's with it. In this function, that number would be 7.
d) Now we need to find the number of terms. For this one, we just need to count how many terms are separated by + or - signs. There are 4 in this function.
