Explanation:
What we need to do is to convert into a new - but still equal - fraction, one with a denominator of 3. In order to convert a fraction, you either divide or multiply both the denominator and the numerator by the same number.
We know that the answer has to be a fraction with the denominator of 3. Take a look at the denominator of - it's 12. Ask yourself: 12 divided by what number equals 3? That number would 4.
So, divide 8 by 4 as well and you would get 2. Therefore, the numerator would be 2 and the answer is .
Answer:
option (b) is correct.
The value of is 0.
Step-by-step explanation:
Given: and
We have to find the value of
Consider the given function
First evaluate value of function f(x) at x = 3 and 1 then substitute it in .
f(3) = 1 + 3 = 4
f(1) = 1 + 1 = 2
Substitute, we get
Solving further , we get,
Now evaluate at t = 0 , we get,
Thus, value of is 0.
Thus, option (b) is correct.
