Given:
The equation of a circle is

A tangent line l to the circle touches the circle at point P(12,5).
To find:
The gradient of the line l.
Solution:
Slope formula: If a line passes through two points, then the slope of the line is

Endpoints of the radius are O(0,0) and P(12,5). So, the slope of radius is


We know that, the radius of a circle is always perpendicular to the tangent at the point of tangency.
Product of slopes of two perpendicular lines is always -1.
Let the slope of tangent line l is m. Then, the product of slopes of line l and radius is -1.



Therefore, the gradient or slope of the tangent line l is
.
Answer:
There is a 0.36% Chance of 1 or fewer in every 24 matches being flawed.
Step-by-step explanation:
Firstly we need to know what 1/10 of 5 is. It is 0.5.
You then need to multiply 24 by 1.5 to get 36. We then need to divide that by 100 to get a percentage and we end up with 0.36%

Answer:
5 yards = 15 feet = 180 inches
Step-by-step explanation:
180 inches plus 18 inches = 198 inches
198 x 3 = 594 inches
594 inches = 49 feet 6 inches = 16 yards 1 foot 6 inches, or 16 yards 18 inches
