Answer:2.5
Step-by-step explanation:
Answer:
.
Step-by-step explanation:
The equation of a circle of radius centered at is:
.
.
Differentiate implicitly with respect to to find the slope of tangents to this circle.
.
Apply the power rule and the chain rule. Treat as a function of , .
.
.
That is:
.
Solve this equation for :
.
The slope of the tangent to this circle at point will thus equal
.
Apply the slope-point of a line in a cartesian plane:
, where
- is the gradient of this line, and
- are the coordinates of a point on that line.
For the tangent line in this question:
- ,
- .
The equation of this tangent line will thus be:
.
That simplifies to
.
