Option B: is the ratio used to convert to miles to feet.
Explanation:
Given that the distance is 1.7 miles
We need to convert the distance 1.7 miles to feet.
The ratio of miles to feet can be determined by finding how many feet are there in a mile.
There are 5280 feet in a mile.
To convert the miles to feet, we need to multiply the mile by 5280 feet.
Thus, the distance is given by
Hence, the distance of 1.7 miles to feet is 8976 feet.
Thus, the ratio that is required to convert miles to feet is
Therefore, Option B is the correct answer.
Answer:
Step-by-step explanation:
For this case we need to find the following integral:
And for this case we can use the substitution from here we see that
, and if we solve for x we got
, so then we can rewrite the integral like this:
And if we distribute the exponents we have this:
Now we can do the integrals one by one:
And reordering the terms we have"
And rewriting in terms of x we got:
And that would be our final answer.
