Answer:
36
Step-by-step explanation:
9 times 4
x = number of hours after 9 am (eg: x = 1 means 1 hr after 9 am, so 10 am)
f(x) = population count x hours after 9 am
f(1) = population count at 10 am (1 hour later)
f(2) = population count at 11 am (2 hrs after 9 am)
f(2) - f(1) represents the difference in population counts from 10 am to 11 am, or put another way, how much the population increased during that time interval.
Answer:
area of the figure=1/2×16×7
=56 m²
Answer: Option A is correct that is 
Explanation:
we will substitute the values of n in given expression
when substituting n=1 we get in =
when n=2 we get 
when n =3 we get 
;3 factorial that is 3! = 3 *2*1 = 6
when n=4 we get 
;4! = 4*3*2*1 = 24
Note: factorial means the product of the terms getting multiplied till 1
suppose n! will be equal to n(n-1)(n-2)(n-3).......1
A linear equation is an equation between two variables that gives a straight line when plotted on a graph.
