...6 and 10 are roots, so x – 6 and x – 10 are factors.
y = a(x – 6)(x – 10).....plug in the point (8, 2) and solve for a:
2 = a(8 – 6)(8 – 10)
2 = –4a
a = –1/2
...y = (–1/2)(x – 6)(x – 10)
...y = (–1/2)(x² – 16x + 60)
...y = (–x²/2) + 8x – 30 <<<------Answer, or:
...y = (–1/2)(x – 8)² + 2 <<<------Answer

units
Step-by-step explanation:
In a right triangle the altitude drawn to the hypotenuse is the geometric mean of the segments at which this altitude divides the hypotenuse.
So,

a. The area of the triangle ABC is

b. The legs of the right triangle are geometric means of the segment adjacent to this leg and the hypotenuse, so

Answer:
Line segment A' B' has a length of 2 units, and line segment C' D' has a length of 4 units.
Step-by-step explanation:
All we need to do is count the units in between the line segments.
