Answer:
Radius of the given circle is r = 2.
Step-by-step explanation:
Given equation of the circle is .
Now we need to find the radius of the given circle .
To find that let's compare with the formula of the circle with is , where r is the radius.
We get
take square root of both sides.
Hence radius of the given circle is r = 2.
Answer:
The domain of the function (cd)(x) will be all real values of x except x = 2.
Step-by-step explanation:
The two functions are and d(x) = x + 3
So, (cd)(x) =
Then, for x = 2 the function (cd)(x) will be undefined as zero in the denominator will make the function (cd)(x) undefined.
Therefore, the domain of the function (cd)(x) will be all real values of x except x = 2. (Answer)
Answer:
C
Step-by-step explanation:
The secant- tangent angle MLK is half the difference of the intercepted arcs, that is
(KN - KM) = 70° ( multiply both sides by 2 to clear the fraction )
KN - KM = 140°
KN - 61° = 140° ( add 61° to both sides )
KN = 201° → C
