Answer:
Step-by-step explanation:
The formula for compound annual interest is A = P(1 + r)t where
A = Accumulated or final amount (double $500 = $1000)
P = Principal or original amount ($500)
r = Rate as a decimal (0.08)
t = Time in years
1000 = 500(1 + 0.08)t
2 = 1.08t
Take the logarithm of both sides. I prefer the natural logarithm ln, but if you're more comfortable with base 10 logs they will work just as well
ln(2) = ln(1.08t)
ln(2) = t*ln(1.08)
t = ln(2)/ln(1.08)
t = 9.0065 years
Check: 500*1.089.0065 = $1000
Answer:
(3, 4)
Step-by-step explanation:
A function is a relation that maps elements from a set (the domain, the set of the inputs) into elements from another set (the range, the set of the outputs).
Such that a function can map each element of the domain into only one element of the range.
Then, if a "function" has:
f(x1) = y1
and
f(x1) = y2
It is mapping the input "x1" into two different outputs, then this is not a function.
Now, we know that the ordered pair (3, -4) is among the points on the graph of the function f(x)
(The first value is the input and the second one is the output)
Then the point that does not belong to the graph, is the point that has the same input and different output.
(3, 4)
Any of the other points could belong to the graph.
It could be miles squared, inches squared, and even centimeters squared (anything squared)
