Major arc CBD measures 300°. Which is the radian measure of its corresponding central angle?
a)4pi/3 radians
b) 5pi/6 radians
c) 5pi/3 radians
d) 11pi/6 radians
Answer:
c) 5pi/3 radians = 5π/3 radians
Step-by-step explanation:
The corresponding central angle can be defined as the angle that is formed when there is a joining together of two radii at the center of the circle.
The circumference of a circle is given as
360° = 2πr
The major arc CBD is 300°
Therefore,
360° = 2πr , radius is not given hence , 360° = 2π
300° = Y (Unknown)
Cross multiply
360Y= (300× 2π)
Y = 600π ÷ 360
Y = (5π÷ 3) radians
Y = 5π/3 radians
Hence the radian measure for the corresponding angle is = 5π/3 radians

Answer: G(x) = cos(x) - 1
Step-by-step explanation:
We know that y = cos(x)
remember that cos(0) = 1.
Now, by looking at the image we can see that G(x) seems to be a vertical shift.
Remember that for a function f(x), a vertical shift of N units is written as:
g(x) = f(x) + N
If N is positive, the shift is up
if N is negative, the shift is down.
In this case we can see that when x = 0, G(0) = 0.
And remember that cos(0) = 1, then G(x) is one unit below the graph of y = cos(x).
Then we can see that G(x) is a vertical shift of one unit downwards.
Then:
G(x) = cos(x) - 1
