31. Gardening The flower color of bigleaf hydrangeas is determined by the soil pH. A gardener growing blue hydrangeas believes that lime may be leaching out of
a nearby sidewalk and increasing the pH of the soil. The gardener measures the
hydrogen ion concentration and
finds it to be 0.0000006 moles per liter. Is the soil
still good for growing blue flowers? Explain.

Need solving this second acceleration problem.

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?
