The factorial of an integer is the product of that integer and all the positive integers less than it. So, 3! = 3×2×1, for example. 0! is defined as 1.

Answer:
See below
Step-by-step explanation:
<u>Taking the readings from the graph</u>
- <u>x .... y</u>
- 0 .... 2
- 2 .... 6
- 4 .... 10
- 6 .... 14
<u>Rate of change for the given line is:</u>
- (6 - 2)/2 = 4/2 = 2
- y- intercept is 2
<u>Equation for the line is:</u>
<u>For the point (40, 76) we can verify with the equation:</u>
The point (40, 76) is close the line but the line doesn't pass through it.
Answer:
Both Distance formula and Slope formula are used to classify quadrilaterals and triangles, as Distance formula is used to calculate the length of each side while Slope formula is used to find the angle of a line with respect to an axis or another line.
We can classify the figure as finding the lengths of each side by using Distance formula. For example, if we find that a quadrilateral has all 4 sides equal, is it a square. If it has opposite sides equal, it can be a rectangle or a parallelogram, and so on. It can also tell whether a triangle is right angled, isosceles or equilateral.
Slope are used to find angles of the lines. If 2 lines have the same slope, it means they are parallel to each other. If the product of their slopes is -1, it means they are perpendicular to each other
