Answer:
m = (y2 - y1) / (x2 - x1) = (10 - 6) / (-1 - (-6)) = 4 / 5 = 0.8
A. 15/35= 3/7. 3/7
But I am not sure about B
The diameter would be 24 and the radius would be 12 I believe :)
Answer:
We are given that:
Now we are asked to show that:
We know that:
Hence using equation (1) we get:
Also we know that:
and
so using above two formula in equation (2) we get:
( since we know that:
)
Hence we have proved that:
