Answer:
(3a + 4b)² / a²b²
Explanation:
This question is difficult to interpret, however the concept being tested in this question is the ability to simplify fractions with variables.
It is a basic rule that only like terms (as denominators) can be added and subtracted from each other, however if you need to add or subtract two fractions with different denominators, it is important to make sure you create a common denominator.
For example, in the beginning, the first fractions are:
16/a² + 24/ab + 9/b²
So it is important to make sure there is a common denominator between all 3 fractions. An easy way of doing this would be to multiply denominators together:
(16b²)/a²b² + (9a²)/a²b² + 24/ab
(9a²+16b²)/a²b² + 24/ab
So now it has gone from 3 fractions to 2, and then to 1:
(9a²+16b²)/a²b² + 24ab/a²b²
(9a² + 24ab + 16b²) / a²b²
Then all that needs to be done is simplify the numerator:
(3a + 4b)² / a²b²
Answer:
LTI system is stable if Impulse response is finite.
so the correct answer is "b"
(b) h2(t) = e-r cos(2t)u(t)
Answer:
They will pay more taxes if they value inventory using LIFO.
The difference in taxes between the two methods is $8400($ 32,550.00 minus $ 24,150.00)
Explanation:
The oil distributor will pay more taxes using LIFO method in valuing the cost of goods sold because LIFO would pick the prices of goods recently purchased which were lower overall compared to prices of goods earlier purchased.
Hence,inventory sold is charged with lower prices and eventually lower costs of good sold s well higher gross profit which translates into higher taxes.
It would be preferable to value inventory sold using FIFO so as to reduce taxes payable by $8400.
