Express the equation 5(x-8)^2=y-12 in the form y=a(x-h)+k, then identify a, h, and k.

9514 1404 393

Step-by-step explanation:

  5(x-8)^2=y-12 . . . . given

  y = 5(x -8)^2 +12 . . . . add 12

Comparing to the required form, we see that ...

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

replace   with   27   and simplify.
