Aboat has a speed of 9 mph in calm water. it takes the boat 4 hours to travel upstream but only 2 hours to travel the same distance downstream. which equation can be used to find c, the speed of the current? 2(9 – c) = 4(9 + c) 9 + c = 4(9 – c) 9 – c = 2(9 + c) 4(9 – c) = 2(9 + c)

40 points plato monica built a remote-controlled, toy airplane for a science project. to test the plane, she launched it from the top of a building the plane traveled a horizontal distance of 50 feet before landing on the ground. a quadratic function which models the height of the plane, in feel, relative to the grouna, at a horizontal distance of x feet from the butiding is shown. since the domain the airplane while it was in the air, the value of the domain should be restricted to the space 1 a. the maximum height of b. the horizontal distance covered by c. all the heights in the trajectory of space 2 a.-10 b.125 c. negative infinity d.0 space 3 a. infinity b.50 c.125 d.225
