y^2 = x isn't a function because there is at least one value of x that produces multiple values of y. In fact, any x value greater than 0 yields two y values. If x = 0, then y = 0 is the only solution. ... Graphically, the equation fails the vertical line test, which is another way to determine that it is not a function.
We know that
Area of a regular polygon = (1/2)*apothem<span>*perimeter
</span>perimeter <span>of the regular decagon=10*a
where
a is the length side of the decagon
in this problem
a=1.8 ft
so
</span>perimeter of the regular decagon=10*1.8----> 18 ft
Area of a regular decagon = (1/2)*2.8*18----> 25.2 ft²
<span>Round to the nearest whole number------> 25 ft</span>²
the answer is
25 ft²
The Unique Shape Theorem states that all regular polygons with the same number of sides are similar to each other. And the immediate result of this theorem is that there is one unique shape for them.
Answer:
Step-by-step explanation:
