Hello.
72:64 = 9:8 To figure this out, simplify both numbers, as you would a fraction, <em>because ratios are fractions.</em>
A variable with a fraction exponent can be rewritten using a radical.
The equations would be A. radical equation
That's the cosine x. The cosine of 0 is 1, so that's how you can tell. The sin of 0 is 0, so that's where the sin graph goes through the y axis
Answer:
540 inches
Step-by-step explanation:
1 yard equals 36 inches. Thus, a 15-yard hose has the measurement in inches of (36)(15) = 540
Given a series, the ratio test implies finding the following limit:

If r<1 then the series converges, if r>1 the series diverges and if r=1 the test is inconclusive and we can't assure if the series converges or diverges. So let's see the terms in this limit:

Then the limit is:

We can simplify the expressions inside the absolute value:

Since none of the terms inside the absolute value can be negative we can write this with out it:

Now let's re-writte n/(n+1):

Then the limit we have to find is:

Note that the limit of 1/n when n tends to infinite is 0 so we get:

So from the test ratio r=0.4 and the series converges. Then the answer is the second option.
