If we take the square of x and square of y and then subtract them:
(csc t)²-(cot t)²=1 ( this eq. gets from basic identity
x²-y²=1......a 1+cot²x=csc²x)

equation 'a' represent the equation of hyperbola which is (x²/a²)-(y²/b²) =1 with given conditions( a=1,b=1)

So, option D is correct

The reyes family but for concert tickets for $252 what was the price per ticket

Bas_tet [7]

If you mean "The Reyes Family bought for concert tickets for $252",

Consider the total price is $252 and that there are four tickets. You are looking for the price of one ticket so view it as

Total Price = $252
Total Tickets = 4

Total Price divided by Total Tickets =
$\frac{252}{4}$
Then divide both sides by four because 4 divided by 4 is 1 ticket.
$\frac{252 \div 4}{4 \div 4} = \frac{63}{1}$

Then you should get 63 divided by 1.
63 divided by 1 is 63, So your answer is

"The price of one ticket that the Reyes Family bought is 63 dollars."
