56÷6.2 equals 9.032≈9 the answer is 9 $
To solve this, I used guess and check.
I started by finding 60²=3600 and 70²=4900. 70² is too much, so I then did 65²=4,225.
After 65², I did 62²=3,844. I knew that was pretty close, so I did 64. 64²=4,096 and 63²=3,969. So, 64² was it.
4,096-4015=81
So, you would need to add 81 to 4015 in order to receive a perfect square, which is 64²(4,096).

Answer: 
</h3>
Explanation:
The identity we'll use is cos(-x) = cos(x) for any value of x.
So cos(-150) = cos(150).
Then locate the angle 150 on the unit circle. The terminal point is 
The x coordinate of this terminal point is the value of cos(150).
That equation is the same as 3m=0, only m=0 works. Do you think they want you to say, all numbers but zero are excluded? Or is the equation different?
Answer: One possible equation could be y = -2x^2 - 3.
The equation that is given would be in the shape of an upside down parabola. It would have a maximum (vertex) at (0, -3).
The point (0, -3) would also be the y-intercept of the graph.
You could change the -2 to any other negative number and the equation would work in your problem.
