Answer:
BQ = 16
QE = 8
Step-by-step explanation:
Centroid of a triangle divides the median in the ratio 2 : 1
Here, let BQ = 2x and QE = x
BQ + QE = BE
2x + x = 24
3x = 24
x = 24/3
x = 8
2x = 2*8 = 16
BQ = 16
QE = 8
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
.
