Homework Statement If a salmon swims straight upward in the water fast enough to break through the surface at a speed of 5m/s, how high can it jump above the water? Homework Equations I am not sure which equation to use. The Attempt at a Solution 0 + 5/2 = 2.5m ?? Is this...

Hello--Thanks for responding. I cannot find an example like this one in my book. Could you give me any hints on how to begin this problem? I am completely self-taught in math and am trying to understand conics, which I have not attempted before. I am also good at following examples and...

Yes, I think you are right--the directions were to write the equation of a hyperbola satisfying these conditions. Can you help?

Homework Statement Write the equation in standard form for the parabola with an axis of symmetry y=0 and focus(-5,0). Homework Equations I think ax^2+bx+c. Also maybe x = -b/2a. But I don't know how to apply these. The Attempt at a Solution I know that focus and vertex lie on...

Homework Statement Write the equatin of the hyperbola whose center is at the origin and has a vertical transverse axis. Homework Equations The equations of the asymptotes are 6x+2y=0 and 6x-2y=0 The Attempt at a Solution I am good at following an example (am an adult who is...

Homework Statement What is an equation for the hyperbola with vertices (3,0) and (-3,0) and asymptote y=7/3x? Homework Equations The Attempt at a Solution I solved this problem but still have a question. The answer is 49x^2-49y^2=441 (I solved it by graphing). However, my...
