Given:
Radius of circle = 12 units
Area of sector = 24π sq. units.
Central angle = x
To find:
The value of x.
Solution:
We have,
We know that, area of a sector is
Where, is central angle, r is radius.
Multiply both sides by 360 degrees.
The value of x is 60 degrees.
Therefore, the correct option is A.
Answer:
Y = x^2/2 - 2x - 2
Step-by-step explanation:
ANSWER
A. No because f(c)=-30
EXPLANATION
The given polynomial is
If x+1 is a factor , then f(-1) must evaluate to zero.
Since f(-1) is not equal to zero, x+1 is not a factor of
