Answer:
D: {0≤x≤20}
R: {0≤y≤200}
Step-by-step explanation:
Domain and range are the possible values of x and y, respectively. For continuous graphs in set notation, inequalities can be used to represent the x and y values. As seen on the graph, the lowest possible x value is 0 and the highest is 20. All of the other values in between are also included. So the inequality 0≤x≤20 expresses all of the values. Additionally, because the circles are closed, the limit values, 0 and 20, are included. Next, the range is found in the same way. The lowest y is 0 and the highest is 200, with the limits included. So, the range inequality is 0≤y≤200.
What does the shape look like?
Ok, so say you are calculating the surface area of the shape in the image below.
You would calculate the area of both shapes (the vertical box and the horizontal one), then subtract the area of the left face of the left rectangle (it is 10x20). That way, you are subtracting the area from the tall box. Make sure when you calculate the area of the short box that you don't include the left face (which is non-existent because it is attached to the tall box). If this is still really confusing (don't blame you if it is!!), let me know and I will walk through and example with you. Hope this helps!!

2 can go into 9 ,4 times remainder is one bring down the 4 that would be 14, 2 can go into 14 ,7 times bring the 1 down 2 can go into 1 ,0.5 times answer is 47.5
Answer:
<h2>2.3 ml</h2><h2 />
Step-by-step
r = the radius of the circle = 1 ml
path length = 2π×r = 2π×1 = 2π ml
then
2π ——-———> 360°
distance from ranger station to petting zoo —————> 130°
then
the distance from ranger station to petting zoo =
130×2π÷360 = 2,268928027593
Answer:
It's 13
Step-by-step explanation:
Well, just use the triangle inequality theorem and pay close attention to angles CAB and EAC... that's all I can say
Hope that helped
