Answer:
n(M) = 4
Step-by-step explanation:
M = (2,4,6,8)
n(M) = Number of values in set M.
n(M) = 4
We need to find the maximum (Vertex of the function)
Let:
L = Length = 1500 - 2x
W = Width = x
The area is given by:

We can find the maximum using the following formula:

Evaluate the area for the value we found previously:

The largest area that can be enclosed is 281250m²
First, we calculate the amplitude
A = (1/2) (xmax - xmin)
A = (1/2) (8 - (-2)) = 5
Since we're given with the period which is pi, then the coefficient of x is just 1. So, the model is
y = 5 sin x
Answer:
625
Step-by-step explanation:
5x5x5x5=625
you multiply five four times because there are four groups of three in twelve
The distance between two cities is
