Question 1171323: 1.) The area of a rectangular pool is 300 square feet. The length of the pool is 5 feet more than the width of the pool. What is the length of the pool?
2.) NASA is designing a new satellite to go on the international space station. The satellite disk is the shape of a parabola. The satellite will be attached to the station on a pole and will place the vertex of the satellite 4 feet away from the surface of the station. The receiver is to be positioned 7 feet above the roof. Write an equation that best models the parabolic cross section of the satellite dish.
3.) Bill Nye is launching a rocket for his next episode. The equation
h (t)= -16t² + 15t + 600 gives the height of the rocket at any given time. How long will it take for the rocket to reach the ground? Round to the nearest hundredth.
4.) The base of a triangle is 4 inches more than twice its height.
If the area of the triangle is 440 square inches, what is the base of the triangle in inches?
5.) 10
Jennifer, standing just outside her apartment building, throws a baseball upward from an initial height of 10 feet above the ground level at an initial velocity of 45 ft/sec. The height of the baseball in terms of elapsed time is a quadratic relationship. The generalized equation is
f(x)=-16x²+v0x+h0 where v0 represents the initial velocity and h0 represents the initial height. Lindsey, on her fourth floor balcony 50 feet above ground level, launches her drone helicopter that ascends at a constant rate of 23ft/sec. If Jennifer throws the baseball at the same time that Lindsey begins the ascent flight of her helicopter, write a system of equations that could be used to determine at what time(s) and height(s) the baseball would possibly strike the helicopter.
