Answer:

C.

Step-by-step explanation:

Domain is only affected if certain values can make the result something that either doesn't make sense or is an error. In your situation, it wants you to find the domain of f/g, which is a fraction. The only rule we have for fractions regarding domain is that we simply can't divide by zero, to find the domain for any fraction with variables in the denominator, what I do is take the denominator, set it equal to 0, and solve for x.

So, if we're taking f/g, we have:

\frac{3x^2 + x^4 + 2}{4x - 3}

4x - 3 makes up our denominator, the bottom part of the fraction. So

4x - 3 = 0

4x = 3

x = 3/4

So the denominator is equal to zero when x is equal to 3/4. This would produce an error in any calculator because you can't divide by zero. The domain here is all real numbers except for 3/4.

(For future problems, the only thing to look out for is if your numerator, the top part of the fraction, factors into something that cancels with the bottom. In that case, it wouldn't affect domain because you aren't actually dividing by anything. For example:

\frac{x^2 - 4}{x-2}

If we factor the top, we see that x^2 - 4 = (x - 2)(x + 2). In this case, we have (x - 2) in both the top and bottom of the fraction, so it cancels out, and from there nothing else is restricting our domain. It would be all real numbers in a case like that.)

Therefore,

Jana bikes 18 miles in one hour.

Step-by-step explanation:

Given:

Jana bikes,

15 miles  ---------------> in 50 minutes

To Find:

How many miles  ------------------> in 1 hour = 60 minutes

Solution:

Let 'x' miles Jana Bikes in 1 hour or 60 minutes

As, 1 hour = 60 minutes

The Ratio of Equation will be

\dfrac{15}{x}=\dfrac{50}{60}

Cross Multiplying we get

x=\dfrac{900}{50}=18\ miles

Therefore,

Jana bikes 18 miles in one hour.
