Answer:
$17.0625
Step-by-step explanation:
9.75 a ticket
As it is 15% every year, in 5 years it would cost 75% more
75% of 9.75 is 7.3125
9.75 + 7.3125 = 17.0625
$220.87 , (it would be $220.88 if you have to round up though

Answer:
A function is a relation that maps inputs from a set called the domain, into outputs from a set called the range.
Such that each input can be mapped into only one output.
So for example, if we have a relation that maps the input 2 into two different values:
f(2) = 4
f(2) = 8
Then this is not a function.
In the case of the problem, we have a student as the input, and the hair color as the output.
So we will have something like:
f(student) = blond
And if this student decides to change his/her hair color to red?
Then the function becomes:
f(student) = red
So for the same input, we had two different outputs, which means that this is not a function.
We also could have the case where a given student has two colors (Californian for example)
Where again, we would see two different outputs for one single input.
A: When you multiply two numbers, their exponents add.
So,

Since 64^1/2 multiplied by itself is 64, then it is the square root of 64.
B: The area is irrational. 7 * √7 is irrational.
