Simplify 12y^7/18y^-3. Assume y=0

For this case we must simplify the following expression:

\frac {12y ^ 7} {18y ^ {- 3}}

We have that by definition of properties of powers, it is fulfilled that:

a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}

Then, we can rewrite the expression:

12y ^ 7 * 18y ^ 3

By definition of multiplication properties of powers of the same base we have:

a ^ m * a ^ n = a ^ {m + n}

So:

12y ^ 7 * 18y ^ 3 = (12 * 18) * y ^ {7 + 3} = 216y ^ {10}

Answer:

216y ^ {10}

When y = 0 the expression is 0

The function f(t) = 20 sin (pi over 5t) + 12 models the temperature of a periodic chemical reaction where t represents time in h
gregori [183]
The answer for the exercise shown above is the second option, which is: <span>Maximum: 32°; minimum: −8°; period: 10 hours.
 The explanation is shown below:
</span> You can make a graph of the function given in the problem above: f(t)=20Sin(π/5t)+12.
 As you can see in the graph, the maximum point is at 32 over the y-axis, and the minimum is at -8.
 The lenght of the repeating pattern of the function (Its period) is 10.
