10. a weight hangs on a spring. the vibration period of that weight is the time in which it makes a complete cycle in motion. suppose the relationship between the vibration period "t" (in seconds) and the weight "w" (in kilograms) is given by t = 2 √(w / 200). find the period t for a spring with a hanging weight of 2.0 kilograms.

Which parent function is an example of a piecewise function? answers: linear parent function quadratic parent function an exponential parent function absolute value parent function pls i’m sorry if this doesn’t make sense

In trapezoid abcd, ac is a diagonal and ∠abc≅∠acd. find ac if the lengths of the bases bc and ad are 12m and 27m respectively.

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?
