(4-1/2) Please answer the questions and solve this quadratic equation which is very similar to the one we did earlier in the week: A goalkeeper threw a ball from the ground to a defender to work up the pitch. Here is the equation that models this situation: -16t2 + 32t

What does the "a" coefficient represent in this type of quadratic equation?

What does the "b" coefficient represent in this type of quadratic equation?

If the units of the equation are feet per second, what do you think the "y" axis represents? The "x" axis?

How many seconds will it take for the ball to hit the ground?

Evaluate cos2θ for cosθ = square root of 3/2

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.

If your teacher tells you to do questions 6 through 19 in your math book for homework, how many questions is that
