WILL GIVE METAL!!! A physics student stands at the top of hill that has an elevation of 37 meters. He throws a rock and it goes up into the air and then falls back past him and lands on the ground below. The path of the rock can be modeled by the equation y=-0.02x^2 + 0.8x+37 where x is the horizontal distance in the meters from the starting point on the top of the hill and y is the heigth in meters, of the rock above the ground. How far horizontally from its starting point will the rock land? Round your answer to the nearest hundredth? *37.00m *67.43m *27.43m *37.78m
its c 27.43m
thank you, can you help me with 2 more questions? Please
absolutly
If an object is dropped from a height of 85 feet, the function h(t) = -16t^2+85 gives the height of the object after t seconds. Approximately,when will the object hit the ground? A. 85.00 seconds B. 69.00 seconds C. 0.33 seconds D. 2.30 seconds
A ball is thrown into the air with an upward velocity of 28 ft/s. Its height (h) in feet after t seconds is given by the function h = –16t² + 28t + 7. How long does it take the ball to reach its maximum height? What is the ball’s maximum height? Round to the nearest hundredth, if necessary 1.75 s; 7 ft 0.88 s; 43.75 ft 0.88 s; 17.5 ft 0.88 s; 19.25 ft
its a 8500 sec.
the second one is d 0.88s ; 19.25ft
2 more?? its fine if you can't
18. A community group is planning the expansion of a square flower garden in a city park. If each side of the original garden is increased by 3 meters, the new total area of the garden will be 225 square meters. Find the length of each side of the original garden. 15 m 3 m 12 m √12 m
the answer to the first one is 67.43
that's not even an option @jamaica25
yep jemica is right or thats what i got to lol
im doing the scecond one right now
