Just wondering if rabbits hibernate in the winter. The winter was really mild up until a few weeks ago and now we are getting lots of snow. Do rabbits hibernate once the snow starts falling? They have been out up until recently because the weather was more like Fall rather than winter.

I want to know if this is right

the Y-intercept of 4xE2 - yE2=9

At the end I got

Square root of -yE2 = Square root of 9

What I did was
get the Square root of 9 which is 3 from the right side and from the left side eliminated the exponent 2 and the square root of -y and I got -y is equal to -3


my final answer was -3


Can you tell me if this is right....

Solve. Give all positive values of the angle between 0º and 360º that will satisfy each. Give any approximate value to the nearest minute only.

1. sin 2 0 = √3/2
2. sin 2x – cos x =0
3. sin ( 2x - 10º ) = ½
4. cos 4x=sin 2x
