Answer:
The value of n must be a positive number.
Step-by-step explanation:
Area of a square is given by where
is the side of the square.
Now, given the area of the square is .
OA) If the area had been zero, i.e., then it means that there is no square at all.
OB) Also, it can not be any other number other than zero as this can include negative numbers as well. And an area being negative makes no sense. (OD) is eliminated as well.
So, the area should be positive.
Answer:
we can draw the graph of cosine with amplitude 2.
Step-by-step explanation:
In the given function g(x) = 2cosx we know the following parameters which are helpful to draw the graph.
Its a cosine graph given in the form of y = acos(Bx + c) + d
Here a is amplitude, period = , c = phase shift, d = vertical shift
We know a = 2, B = , c = 0, d = 0.
