For a short time after a wave is created by wind, the height of the wave can be modeled using y = a sin , where a is the amplitude and t is the period of the wave in seconds.
write an equation for the given function given the amplitude, period, phase shift, and vertical shift.
amplitude: 4, period = phase shift = vertical shift = -2

You are assembling pieces of an iron gate to complete a fence. the finished gate will look like the one below. in order to assemble the gate it is important to under how the pieces are related. part 1: how are pies 1 and 2 in the archway related? part 2: how are the rectangular sections 5 and 6 in the center of the gate related to each other?

Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

1- 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.2- 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 the first question?
