Question 463947: The function s(t) = 16t² is used to approximate the distance s, in feet, that an object falls freely from rest in t seconds.
Suspended 1053 ft above the water, the bridge over Colorado’s Royal Gorge is the world’s highest bridge. How long would it take an object to fall freely from the bridge?
Im not sure of how to solve this equation is there someone who might help with this question. I would appreciate your help. Thank you so much !

Question 463954: I need help with system of equations with 3 variables.
1. Solve x + y = z
-2x – 4y + z = -31
x + y + z = 22
2. 3x – y + 2z = 6
-x + y = 2
x – 2z = –5
3. Solve 2x + 3y + 3z = 5
4x + 5y + 3z = 13
3x + 2y – 2z = 13

Question 464984: I am taking integrated algebra online, and my teacher gave us two standard equations for a parabola in the conic section, but she failed to explain how we decide which one to use when given a problem like "focus (-2,1)and directrix x = 3". the two equations she gave us are the vertical equation "(x - h)^2 = 4p (y - k)" and the horizontal equation "(y - k)^2 = 4p (x - h) i know how to figure out what h, k, and p are but she didn't explain how we are suppose to determine which equation to plug our answers into. The two equations give you two different answers when you figure the problem out.
