Help with any would be very appreciated!
1. A triangle with the following can't exist, right? Sides of 3cm, 3cm and a non included angle of 90 degrees. BUT, can i change one of the sides so that exactly 2 triangles exist? How..?
2. Parabola has an axis of symmetry at x=2 and a focus at (2,5). What is a possible eq. for the parabola in standard form?
Right now I had: vertex at (2,0) And my parabola opens upwards. My directrix would be y=-5 ya? And my eq is (x-2)^2=-20(y-5)....Why is this wrong?
3. Give a general form eq. of an ellipse and a hyperbola. Explain how u know that the eq's yield the intended results. (THEN, convert into standard form).
HELP!!!!! PLEASE AND THX!!(Rofl)
