Answer:
Step-by-step explanation:
To solve this we should use the Euclidean division :
- Our polynomial function is 16-2x³-6x²+x+9=-2x³-6x²+x+9
- we should divided by : 4+3x-2=3x+2 and see the rest
Here is a picture with the operation
- the rest is 47/9 so the number I SHOULD SUBSTACT IS 47/9
<u>Answer: </u>
The population of a city has decreased by 38% since it was last measured. If the current population is 27,900 .Previous population of city was 45000.
<u> Solution: </u>
Given that current population of city is 27900.
Also, population of a city has decreased by 38% since it was last measured.
Let assume that population of city when it was last measured = x
Decreased of 38% means x-38% of x . we can write this as,
So current population is
Equating above expression to the given value of current population, we get
x=45000
Hence previous population of city was 45000.
