QR is a diameter and Q(1,8) and C(3.5,2) are points on a coordinate plane. Find and state the coordinates of Point R

The coordinates of point R are .

Step-by-step explanation:

From Geometry we understand that magnitude of Diameter is twice the magnitude of Radius. Vectorially speaking, both radius and diameter are collinear. That is:

(1)

Where:

- Vector radius.

- Vector diameter.

If we know that and , then coordinates of point R are, respectively:

The coordinates of point R are .

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
