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

ht and the high and low temperature during the day are 64 and 26 degrees, respectively. Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t.\

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)

Required:

v=?

Formula:

<em>v</em><em>=</em><em>l</em><em>*</em><em>w</em><em>*</em><em>h</em>

Solution:

v=l*w*h

v=6in*9in*7in

v=54in^2*7in

v=378in^3
