If a pentagon is regular, then all of the sides are the same length. This means that
So, if , the lengths of the sides evaluate to
So, all the sides of the pentagon are 21 units long, and AB is 21 units long as well, because all sides are the same length.
Answer:
Loss %age = 25%
Step-by-step explanation:
<u><em>Cost Price of Item</em></u> = 250,000/-
<u><em>Loss </em></u>= 1/4 = 0.25 of 250,000
=> 62,500 /-
<u><em>%age Loss</em></u> =
=> 62,500 * 100 / 250,000
=> 6,250,000/250,000
=> 25 %
Domain is the entire span left to right (on the x-axis) that the graph is on. Since the graph goes from x=-4 and ends at x=4, the domain would be from -4 to 4. The circle at -4 is open, so it does not include the point at -4, just everything leading up to it. So, the domain would be
The range is similar, it is the entire span that the graph goes up and down (on the y-axis). The graph starts at the bottom at y=-2, and ends at y=5. The bottom point (4,-2) is closed, so the graph includes that point, and the top point (-4,5) is open and doesn't include the point. Therefore, the range would be
