Answer:
Nina's rate in miles per hour is 2.7 miles/hour
Nina bikes faster
Step-by-step explanation:
we know that
1 hour=3,600 seconds
1 mile=5,280 feet
<em>Convert feet to miles</em>
63,360 feet=63,360/5,280=12 miles
Convert seconds to hours
3,400 sec=3,400/3,600=0.94 hours
Find Nina's rate in miles per hour
12/0.94=12.7 miles/hour
Sophia's rate in miles per hour is 10 miles/hour
Compare the rates
12.7 miles/hour > 10 miles/hour
therefore
Nina bikes faster

Answer:
Part 1)
A
Part 2)
C
Step-by-step explanation:
1)
We are given:

And that:

And we want to now for which values of x is h(x) undefined.
So, by substitution:

Remember that for rational functions, the function will be undefined if and only if the denominator is 0.
This is because we cannot divide by 0.
So, to find the values for which the denominator is 0, set the denominator to 0 and solve for x. Therefore:

Add 9 to both sides:

Take the square root of both sides. Since we are taking an even-root, we will need plus/minus. Therefore:

So, h(x) is undefined for ±3.
Our answer is A.
2)
We are given:

And we want to find:

So:

Distribute:

Combine like terms:

Rewrite:

Factor out:

So, our answer is C.
