Answer:
62,500 pi
Step-by-step explanation:
diameter = radius + radius
d = 2r
r = d/2
A = 4pi r^2
= 4 pi (d/2)^2
= 4pi d^2/4
= 4pi* 250^2/4
= 4pi * 62,500/4
= 4pi * 15625
= 62,500 pi
A jump discontinuity occurs when the limits as x approaches a number from the left and right are not equal. Basically, the graph "jumps" from one number to another at that x value.
A point discontinuity occurs when limits as x approaches a number from the left and right are equal, but the actual value of f(x) at x is not equal to the limit. Basically, a point is missing and there is a "hole" in the graph at that x value.
Looking at your graph, you can see that at x=0, the graph "jumps" from a value of 2 as the graph approaches x=0 from the left to a value of 1 as the graph approaches x=0 from the right. That means there is a jump discontinuity at x=0.
You can also see that there is a "hole" in the graph at x=-2 and x=8 as seen by the open circle. There is no hole at x=3 because the circle is filled in. That means there is a point discontinuity at x=-2 and x=8.
Your answer is B) jump discontinuity at x=0; point discontinuities at x=-2 and x=8.
1/2 because it is a fraction
Is 172 the area or perimeter.
