The surface are of the shape is 251.5 units (sorry if that is wrong)
Answer:
50°
Step-by-step explanation:
An inscribed angle is half the measure of its intercepted arc. Here, arc AC is ∠B's intercepting arc. Arc AC is 100°, and 100/2 = 50, so ∠B is 50°.
Answer:
ANSWER
Step-by-step explanation:
Answer:
The quadratic equation is: 
Step-by-step explanation:
If the roots of the quadratic equation are "-6" and "6", then it must have the following factors: 
Therefore, we can write the equation in factor form as:

where a is a real number constant factor. Now, this equation in standard form will look like:

Therefore, using the information about the leading coefficient being "1" (one), we derive that the constant factor
must be "1". The final expression for the quadratic becomes:

I don't know the real answer, but I think it is C. (I am sorry if I am wrong).
