Which equation would best solve the following problem?
maria releases a javelin 1.5 meters above the ground with an initial vertical velocity of 22 meters per second. how long will it take the javelin to hit the ground?
–4.9t^2 + 22t + 1.5 = 0
–16t^2 + 22t + 1.5 = 0
–4.9t^2+ 22t = 1.5
–4.9t^2 + 1.5t + 22 = 0

The number of fish in a lake can be modeled by the exponential regression equation y=14.08 x 2.08^x where x represents the year

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?

`if you have a set of parallel lines a and b cut by transversal x, if angle 1 = 167 degrees, what is angle 4 and why. also what is the measure of angle 5 and why? you need to use the names of the angle relationship and explain. ''.
