In circle A below, if angle BAC measures 15 degrees, what is the measure of arc BC?
2 answers:
Answer: 15°
Step-by-step explanation:
It is important to remember that, by definition:
Therefore, in this case, knowing that the angle BAC (which is the central angle) in the circle provided measures 15 degrees, you can conclude that the measure of arc BC (which is the intercepted arc) is 15 degrees.
Then you get that the answer is:

Answer:
4 cm
Step-by-step explanation:
The equation of a parabola with its vertex at the origin can be written as ...
y = 1/(4p)x^2
The problem statement tells us that one point on the parabola is (x, y) = (12, 9). We can put these values into the equation and solve for p, the distance from the focus to the vertex.
9 = 1/(4p)(12^2)
9×4/144 = 1/p = 1/4 . . . . . . . . multiply by the inverse of the coefficient of 1/p
Then p = 4, and the bulb is 4 cm from the vertex.
Answer:
Consider the expression . q is called the quotient, a is is the dividend and b is the divisor.
Since q is a multiple of 6, then q has the form for some integer k.
Since a is a multiple of 9, then a has the form for some integer s.
Since b is a factor of 12, then if 12 can be expressed of the form , for c an integer. Then b has the form
Replacing the preview expression in the initial expression we obtain:
Then is a equation to Isabel's problem.
