The number of students at a certain school is 1220 and is increasing at a rate of 10%
per year. Identify the exponential growth function to model this situation. Then find
the number of students in the school after 7 years.
O
y = 1220(110) '; 2000
O
y = 1220(1.1) ; 2300
y= 1220(1.01)'; 2343
y = 1220(1.1)': 2377

Which equation represents the model shown? a)1/3 divide 1/6 = 2 b)2/3 divide 1/6 = 2/18 c)1/3 divide 1/6 = 1/18 d)2/3 divide 1/6 =4

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?
