The point on the number line represents C) 
.
Step-by-step explanation:
Step 1:
The distance between 0 and 1 is split into 4 partitions.
The value for each distance is given by dividing the difference by the number of partitions; 
So each partition represents a value of 
Step 2:
The value of the first partition; 
,
The value of the second partition; 
The value of the third partition; 
,
The value of the fourth partition; 
The point on the number line is in between the zero and the second partition so it is the first partition which has a value of
Answer:
<h3>note: all the twos are to the power</h3>
100=(x−1)2(y+3)
Step-by-step explanation:
Suppose the centre of the circle was at the origin (where the x axis crosses the y axis). Then the equation would be:
r2=x2+y2
The reason for this format is that the length of the radius (which is of fixed length) can be related to x and y by Pythagoras. However, the circle centre is not at the origin. It is at
(x,y)→(1,−3)
So we can mathematically make this work by 'theoretically' moving the actual centre to a new centre located at the origin.
Thus we would have:
r2=(x−1)2+(y−(−3))2
r2=(x−1)2+(y+3)2
But the radius is 10 so we have
(10)2=(x−1)2+(y+3)2
100=(x−1)2+(y+3
