Determine the equation in standard form of the hyperbola that satisfies the given conditions. Vertices at (4,6),(-4,6)\(;\) slope of one asymptote is -2
Use a graphing utility to graph the given equation. $$\frac{(x+1)^{2}}{15}-\frac{(y-3)^{2}}{3}=1$$
For the ellipse with equation \(\frac{(x+2)^{2}}{25}+\frac{(y-3)^{2}}{144}=1,\) find the distance from either endpoint of the major axis to either endpoint of the minor axis.
Suppose Jacob hits a baseball from a tee that is 3 feet tall. He hits the ball with an initial velocity of 120 feet per second at an angle of \(50^{\circ}\) to the horizontal. What is the maximum distance the ball will travel?
Jim kicks a football from the ground with an initial velocity of 140 feet per second at an angle of \(45^{\circ}\) to the horizontal. (a) Find the parametric equations that give the position of the ball as a function of time. (b) When is the ball at its maximum height, to the nearest hundredth of a second? What is its maximum height, to the nearest tenth of a foot? (c) How far did the ball travel? Round your answer to the nearest foot.
