The height of a javelin after it has left the hand of the thrower can be modeled by the function h = 3(4t-2)(-t + 4), where h is the height of the
javelin and t is the time in seconds. How long is the javelin in the air?

Solve -2(4y + 6) = 52. 5 -5 8 -8 and !

The quadratic function h(t)=-16.1t^2+150 choose the graph representation

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
