Answer:
3 is the solution one solution
2 is the solution one solution
3 is the solution one solution
Step-by-step explanation:
Answer: -0.5.
Step-by-step explanation:
The constant of variation k for the direct variation is given by:-
The given table:
x f( x )
0 0
2 -1
4 -2
7 -3.5
Then,
Hence, the constant of variation k for the direct variation is -0.5.
It might either be a right triangle or a cute triangle
The formula to find the arc length L is
L = r*theta
where r is the radius and theta is the central angle in radians (this formula will not work if theta is in degrees)
If the central angle is 1 radian, then theta = 1 and
L = r*theta
L = r*1
L = r
So the arc length is the same as the radius
Answer: Choice A) The radius of the circle
