50 + 12m = 460
Subtract 50 from both sides
12m = 410
Divide 12 from both sides to isolate m
m = 34 1/6
A circle measures 360°.
Since ∠DEF is equal to 70°, the rest of the circle will have a measure of 360 - 70 = 290°.
Central Angle and Arc relationship:
It states that the measure of the central angle and the arc that it intercepts are equal in measure.
Since ∠DEC is a central angle, its intercepted arc DF is also equal to 70°.
With this given facts, arc DGF is equal to 290°.
We can only solve for the degrees because radius is not given. Had it been given, the fraction 290°/360° will be multiplied to the circumference of the circle to get the length of the arc DGF.
Answer:
only G is even
it's obvious that g is even. g(x)= |x|
for ...
it's a quadratic equation with roots -1 and 4,
thus the equation will be
(if you have roots of a quadratic equation, the equation is
or
now, put the point (0,4)
so the equation is
now if you put
you get
which is not the same.
hence
Answer:
the diameter is twice the circle radius, or 20
Step-by-step explanation:
Recall that the radius is half the diameter <=> the diameter is twice the radius. In this problem we need to find the radius first, then multiply it by 2 to obtain the diameter.
We need to determine the distance between the center of the circle Q(6, -4) and the point R(14, 2) on the circle.
The Pythagorean Theorem applies here. Going from Q to R, x changes from 6 to 14, or 8 units, which is the horizontal leg of a right triangle, and y changes from -4 to 2, or 6 units. Thus, according to the Pythagorean Theorem, the length of the hypotenuse of this triangle is
r = √(6² + 8²) = √100 = 10
and so the diameter is twice that, or 20.
