Answer:
Answer: Domain is the set of all possible input for which the relation is defined. In this relation x is the variable that defines all inputs of the relation and y is the variable that defines all outputs of the relation. In the ordered pairs, the set of x-coordinates is called domain of the relation.
Step-by-step explanation:
Use a calculator.
(23/13.8)-18=-16.333=(-16)-(1/3)
The rule of 72 will have you divide 72 over the interest rate in percent form. Ignore the percent symbol
So we'll divide 72 over 8.47 to get...
72/8.47 = 8.50059
which is roughly 8.5 years for the money to double
If we round to the nearest whole number, then it takes 9 years for the money to double (according to the rule of 72). The year 1999 isn't listed so the next best choice is the year 2000. So I'm fairly confident the answer is C) 2000. Though your teacher may have 1998 in mind for some reason. If it were me, I'd go with 2000 because the year 1998 will have the account balance short of the goal of $10,000.
Answer: Choice C) 2000
