Think about two numbers stacked on each other vertically and then a line in between
Answer:
C. (8, 2)
Step-by-step explanation:
To find which point is not on the graph, find which set of coordinates makes the equation incorrect.
When plugged into the equation, the point (8, 2) makes it incorrect:
y = 10 + x
2 = 10 + 8
2 = 18
2
18
The equation is incorrect because 2 is not equal to 18.
So, the point that is not on the graph is C. (8, 2)
You divide 2 by 9 which is .2222--- or .2 if you round it to the nearest tenths.
Whenever you want to change a fraction to a decimal, you divide the numerator by the denominator.
Area of a regular polygon = 1/2 x apothem x perimeter
We know that each side is 10, because if you draw a segment from the center to a vertex it creates a 30-60-90 triangle (those are the angles). This type of triangle has a ratio for its sides where the longer side is radical three times as long as the shorter leg. This shorter leg happens to be half of a side of the polygon. Knowing that the polygon has 6 sides, we can multiply 10 by 6 to get the perimeter.
Area of polygon = 1/2 x apothem x perimeter = 1/2 x 5

x 60
=30 x 5

To the nearest tenth of a cm, the area of the polygon is 260 cm squared</span>
