Write 12 ten thousands, 8 thousands,14 hundreds, 7 ones in standard form
Cloud [144]
<span><u><em>The correct answer is: </em></u>
129,407.

<u><em>Explanation</em></u><span><u><em>: </em></u>
12 ten-thousands = 12*10000=120,000.
8 thousands = 8*1000=8000;
<u>this gives us</u> 120,000+8,000=128,000.

14 hundreds = 14*100=1400;
<u>this gives us</u> 128,000+1,400=129,400.

7 ones = 7*1=7;
<u>this gives us</u> 129,400+7=129,407.</span></span>

Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the temperature is 45 degrees at midnig
Nady [450]

Answer:

D = 45+19*sin(\frac{\pi}{12}*t)

Step-by-step explanation:

The amplitude (A) and the mean (M) temperature are given by:

A=\frac{64-26}{2}\\ A= 19\\M=\frac{64+26}{2}\\ M= 45\\

The mean temperature, 45 degrees. occurs at midnight (t=0) and the frequency is f=24h. Therefore, the temperature D, in degrees, as a function of t, in hours, is:

D = M+A*sin(\frac{2\pi}{24}*t)\\D = 45+19*sin(\frac{\pi}{12}*t)
