Question 70

A circle has the equation $x^2 + y^2 = 10$

Write down the coordinates of the centre of the circle.

[1]

Write down the exact length of the radius of the circle.

[1]

$P\,$ is the point (1,3) on the circle $x^2 + y^2 = 10$

Work out the equation of the tangent to the circle at $P$ .

[4]

Hence work out the coordinates of the point where the tangent meets the $x$ -axis.
