Answer: 20.5

Step-by-step explanation:

From the measure of the length of the sides of the triangle, 9, 40 and 41 we can infer that the triangle is a right angled triangle. 9-40-41 is a Pythagorean triplet.

In a right angled triangle, the circumradius is half the hypotenuse.

In the given triangle, the hypotenuse = 41.

Therefore, the circumradius is 41÷2= 20.5 units.

Answer:

Graph B

Step-by-step explanation:

According to data in the table we see pairs of points:

(3, 75), (5, 125)

This gives us the rate of change:

(125 - 75)/(5 - 3) = 50/2 = 25

The y - intercept is zero:

75 = 3*25 + b
75 = 75 + b
b = 0

The line is:

y = 3x

This is the line on the graph B

Note. Its not clear what is needed regarding the table on the bottom
