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
(1000 mg) / (1.5 (cm cubed)) =
666.666667 kg / m3

Y = 3x
How to solve:
y2 - y1/x2-x1
27-15/9-5
= 12/4 = 3
Looks like you got it already :)
Y+1=[m(the slope)](x+2), y=mx+2m-1, it is impossible to get the answer without the graph.
