Lets O is the center of the circle and Lets A is a point cut on CD from O
mCD = m<COD
OA is perpendicular bisector of CD so OA = 1/2 CD = 1/2(12.7) = 6.35
Sin (DOA) = AD/OD = 6.35 / 9.06
Sin DOA = 0.7009
<DOA = 44.5°
<COD = 2 x 44.5°
<COD = 89°
mCD = <COD = 89°
Answer: 89°
1/(-9)^2 = 1/81 just that
Answer:
why does this hurt my head so much
Step-by-step explanation:
The quadratic function when graphed out should look like either a 'U' or an 'n' (parabola). Quadratic functions have formulas which are typically in the form of: A(x^2)+Bx+C where A, B, C are numbers and if you plot them then as mentioned before you should get a parabola.
