Answer:
-x
Step-by-step explanation:
The derivative of f(x) at x=3 is 2x=6 approaching from the left side (apply power rule to y=x^2). The derivative of f(x) at x=3 is m approaching from the right side. In order for the function to be differentiable, the limit of derivative at x=3 must be the same approaching from both sides, so m=6. Then, x^2=mx+b at x=3, plug in m=6, 9=18+b, so b=-9.
So this question basically asks what is 2 x 3 x -2³ and that equals 6 x -8 = -48
Answer:
AGE=150
Step-by-step explanation:
FHD and GHC are supplementary, so:
180-30=150
CHG is corresponding to AGE, so AGE=150
The vertices are on the circle
that means that the length should be the radius
