Aball is dropped from the top of a building with a height of 500 feet. the height of the ball at time, t, can be modeled by the function h(t)=-4.9t^2 + h_0 where h_0 is the initial height of the ball. approximately how long does it take for the ball to reach the ground?

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
