Given:
Center of a circle is at point C(-1,2).
AB is the diameter of the circle.
Coordinates of the point A are A(2,6).
To find:
The coordinates of point B.
Solution:
Let the coordinates of point B are (a,b).
If AB is the diameter of the circle, then A and B are end points of diameter of the circle and the center C is the midpoint of AB.
Point C = Midpoint of AB
On comparing both sides, we get
Similarly,
Therefore, the coordinates of point B are (-4,-2).

Answer:
f(x) = 2x
Step-by-step explanation:
Remark
What I'm about to do is probably not the best way to do this question, but it is right. The plan is to take out a common factor on the right of f(x - 2) and then derive f(x) from that.
Solution
- f(x - 2) = 2x - 4 Take out a common factor on the right of f(x -2)
- f(x - 2) = 2(x - 2) Now what that means is that in the original equation, wherever you saw an x, you put in x - 2. So the original equation must have been
Check
- f(x) = 2x To check this put x - 2 back in
- f(x - 2) = 2(x -2) Remove the brackets.
- f(x - 2) = 2x - 4 which is what it should be.
Answer:
4.21, 4.22, 4.23, 4.24
Step-by-step explanation:
We're given:
- The number is bigger than
- The number is smaller than 4.25
is 0.2.
How do we know this? Think about 100%. When we divide 100% by 5, we get 20%. 20% in decimal form is 0.2.
This means that is the same as 4.20.
What's a number with two decimal places that's greater than 4.20, but less than 4.25?
