Which ordered pairs lie on the graph of the exponential function f(x)=128(0.5)
a.(0,1)
b.(1.64)
c.(3,16)
d.(8,0.5)

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?

Is a square always, sometimes, or never a parallelogram

Ineed here’s a picture of the question
