PL HELP A pendulum's first swing has an arc of 24 inches. As the pendulum swings back and forth, the arc length for each successive swing is 3/4 of the previous swing. If this pattern continues, at which swing of the pendulum will the length of the arc be less than 4 inches?

If 1 is divided by the sum of y& 4.the result is equal to 3 divided by 4, find the value of m

In a graph with several intervals o data how does a constant interval appear? what type of scenario produces a constant interval?

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?
