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:
$6250
Step-by-step explanation:
6250x.075x8=3750
6250+3750=10,000
132 + 146 + c should be greater than or equal to 325, and c should be greater than or equal to 47.
Answer:
288 is your answer. 8 is your answer.
Step-by-step explanation:
If you want to know how many logs all together, all you do is multiply.
48 x 6 = 288
288 is your answer.
Or division it is
48/6 = 8
8 is your answer.
Answer:
(1) 820
(2) 1920
Step-by-step explanation:
(1) solving 20 x 41, using associative property.
20 * 41 = (2 x 10) x 41 = 2 x (10 x 41)
= 20 x 41 = 2 x 410
= 820 = 820
(2) distribute 32 as 30 + 2 and solve.
60 x 32
= 60 x (30 + 2) = 60(30) + 60(2)
= 1800 + 120
= 1920
