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:
660 in^2
Step-by-step explanation:
The formula to calculate area of trapezoid : (a+b)/2*h (a: base, b: base, h: height)
(30+36)/2*20 = 660 in^2
Divide it by -1 to get positive 81
Answer:
We have a line L.
Remember that in two dimensions, we can write a line as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
And then using one of these points, we can find the value of b.
Then wen we got the equation for the line:
y = a*x + b
We can input a point (x, y)
And see if the equality is true, then the point belongs to the line L.
