Answer:
The number is 50.
Step-by-step explanation:
0.6x=30
x=30/0.6
x=50
Answer:
C (3,10) center and radius 3
Step-by-step explanation:
The equation of a circle can be written in the form
(x - h)² + (y– k)² =r²
where (h,k) is the center and r is the radius
Given
(x - 8)² + (y– 10)² = 9
Rewriting
(x - 8)² + (y– 10)² = 3²
We know that
(8,10) is the center and 3 is the radius
Answer:
32.064
Step-by-step explanation:
Answer:
Reference angle will be
Step-by-step explanation:
We have given
It can be written as
As 240° is lie in the third quadrant
And we know that for third quadrant
Reference angle is given by
So reference angle will be
Now
The graph crosses the x axis where g(x) = 0 , so:-
x^2 - 5 = 0
x^2 = 5
x = sqrt5 or -sqrt5
so grapg corosses the x axis at (-sqrt5,0) and (sqrt5, 0)
