Answer:
The answer is d i believe
Step-by-step explanation:
Answer:
15 hours.
Step-by-step explanation:
20 can be divided into quarters, 3 quarters is 15/20 hours.
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
