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
Answer:
$8.33
Step-by-step explanation:
24.99 ÷ 3 = 8.33
3,045 = 210x
3,045/210 = 14.5
A good estimate of the cost would be:
$14.50
