The notation, more or less indicates that, the first value in the sequence is 2, the next term's value, will be "current value, times -4 and plus 2"
thus
Answer:
8,246,160
Step-by-step explanation:
Population density
= people/area
Given
Population density of New York = 17,620 and
Area = 468 square mile
Therefore,
17620 = people /468
Cross multiply
People = 17620 x 468
= 8246160
There are 8,246,160 people in New York
Answer:
The correct option is B.
Step-by-step explanation:
A function is called an exponential function if it has common ratio.
A function is called an linear function if it has common difference.
In option A.



Since the given table has different ratio, therefore it is not an exponential function. Option A is incorrect.
In option B.



Since the given table has common ratio, therefore it is an exponential function. Option B is correct.
In option C.



Since the given table has different ratio, therefore it is not an exponential function. Option C is incorrect.
In option D.



Since the given table has different ratio, therefore it is not an exponential function. Option D is incorrect.
--(-k)------------(-3)-------(-2)------(-1)-----0----(+1)---(+2)---(+3)---------------(+k)--
You will notice that all values on the left of "0" are negative and positive on the right .
Moreover
+1 is symmetric to -1 about "0"
+2 is symmetric to -2 about "0"
+3 is symmetric to -3 about "0"
and +k is symmetric to -k about "0"
So the opposite of -k is +k and it's symmetric of -k vs."0"
