Answer:
Step-by-step explanation:
3 tickets to attend an Off-Broadway show cost $81,
4 tickets cost $108; and
5 tickets cost $135.
Let the price of a ticket=k
Therefore:
Solving any of the equation above gives: x=27
We therefore have:
Let y be the total cost of x tickets
- From the above, the constant of proportionality, k=27
An equation for the relationship is therefore:
y=27x (where x is the number of tickets and y is the total costs (in $)).
Cos 12 = sin (90 - 12) = sin 78
Answer:
A rational exponent is an exponent that is a fraction. If the fraction has an even denominator, the root will be of an even number (like the square root, the 4th root, etc.). Think about it when you square something: -2 • -2 = 4, 2 • 2 = 4. No matter the sign, any number multiplied by itself an even number of times will make a positive number. So, you can't take the square root of a negative number because it is impossible to get a negative number when squaring! This applies to ALL even roots/exponents. So, (-1)^½ does not exist! Look: (-1)^½ becomes √(-1) which is an imaginary number!
