the center of a circle is on the line y=2x and the line x=1 is tangent to the circle at (1,6).find the center and the radius

Julli [10]

The radius and the center of the circle are 4 units and (1,2), respectively

<h3>How to determine the center and the radius?</h3>

The center of the circle is on

y = 2x and x = 1

Substitute x = 1 in y = 2x

y = 2 * 1

Evaluate

y = 2

This means that the center is

Center = (1, 2)

Also, we have the point of tangency to be:

(x, y) = (1, 6)

This point and the center have the same x-coordinate.

So, the distance between this point and the center is

d = 6 - 2

d = 4

This represents the radius

Hence, the radius and the center of the circle are 4 units and (1,2), respectively

Answer:

After factorization we got,

$(6x + 5)(x - 2)$

Step-by-step explanation:

here's the solution: -

=》

$6 {x}^{2} - 7x - 10$

=》

$6 {x}^{2} - 12x + 5x - 10$

=》

$6x(x - 2) + 5(x - 2)$

=》

$(6x + 5)(x - 2)$
