2. By the secant rules,
BC² = DC*(DC +diameter)
Substituting the given information, you have
8² = 4*(4 +2*radius)
64 = 16 +8*radius
48/8 = radius = 6
radius = AB = 6
3. By the Pythagorean theorem,
AC² = BC² +AB²
Substituting the given information, you have
12² = 9² +AB²
144 -81 = AB² = 63
AB = √63 = 3√7
radius = AB = 3√7
Answer:
A & B
Step-by-step explanation:
15/20 is not equal
6/8 is not equal
30/50 is equal
12/20 is equal
(-3,7) and (3,3)
Slope = (7 - 3)/(-3 - 3) = -4/6 = -2/3
Equation:
y - 3 = -2/3 (x - 3)
y - 3 = -2/3 x + 2
y = -2/3 x + 1
Answer
y = -2/3 x + 1
