dan has already delivered 48 donuts today. for the next few hours, dan will deliver 60 donuts per hour. match the number of donuts dan will have delivered after a given number of hours to the corresponding recursive function.
a. number of donuts delivered 2 hours from now. b. number of donuts delivered 7 hours from now c. number of donuts delivered n hours from now. d. number of donuts delivered 6 hours from now.

1. next= now+ 6*60
starting at 48

2. next=now +60+60
starting at 48

3.next= now +420

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?

Tell whether the two rates form a proportion

Use a standard normal table to determine the probability. give your answer as a decimal to four decimal places. −1.5< < 1.5)
