Answer: Undefined
Step-by-step explanation:
Sec 3
/2 = 1/Cos(3
/2) = 1/0 = Undefined
Point is (4,7)
So y = 7 = 4^2 + c
c = 7 - 16
c = -9
B, because you would just assume the line continues forever on both sides.
<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.
