The answer for the question is a
Let the required number be x, then to create a proportion using the form

Thus, let 15 be

of x, then

Therefore, 15 is <span>

of</span> 1,000
The domain of a function is the set of values for which the function is defined; i.e. the function outputs a value for an input from the domain. That means that we must be able to plug in numbers for x and get numbers from y.
We can't take the square root of negative numbers (ignoring imaginary numbers), so that means we can take the square root of any non-negative number; i.e. we can take the square root of zero, and any positive number.
Therefore, any function that can take in values of x that are zero or more than zero has the same domain as the given function. So

is a function that has the same domain as

.
Answer:
1. 19.375 inches
2. 8.808 km
Step-by-step explanation:
1. Diego's height - his brother's height
59.5 - 40.125
19.375 inches
Therefore, Diego is 19.375 inches taller than his brother.
2. distance needed to run - distance covered
10 - 1.192
8.808 km
Therefore the runner has to run 8.808 kilometres left to run to finish the race.
