The answer will be 68 as for adding 17 to all four sides of the rhombus and not the circle
Answer:
a) The rate of change of the brightness after t days is ![B^{\prime}(t) = 0.204525\pi\cos{(0.4545\pi t)}](https://tex.z-dn.net/?f=B%5E%7B%5Cprime%7D%28t%29%20%3D%200.204525%5Cpi%5Ccos%7B%280.4545%5Cpi%20t%29%7D)
b) The rate of increase after one day is of 0.0915.
Step-by-step explanation:
The brightness after t days is given by:
![B(t) = 4.2 + 0.45\sin{(\frac{2\pi t}{4.4})} = 4.2 + 0.45\sin{(0.4545\pi t)}](https://tex.z-dn.net/?f=B%28t%29%20%3D%204.2%20%2B%200.45%5Csin%7B%28%5Cfrac%7B2%5Cpi%20t%7D%7B4.4%7D%29%7D%20%3D%204.2%20%2B%200.45%5Csin%7B%280.4545%5Cpi%20t%29%7D)
A) Find the rate of change of the brightness after t days.
This is ![B^{\prime}(t)](https://tex.z-dn.net/?f=B%5E%7B%5Cprime%7D%28t%29)
The derivative of a constant is 0, the derivative of
is ![a\cos{at}](https://tex.z-dn.net/?f=a%5Ccos%7Bat%7D)
So, in this case, we have that:
![B^{\prime}(t) = 0.45*0.4545\pi\cos{(0.4545\pi t)} = 0.204525\pi\cos{(0.4545\pi t)}](https://tex.z-dn.net/?f=B%5E%7B%5Cprime%7D%28t%29%20%3D%200.45%2A0.4545%5Cpi%5Ccos%7B%280.4545%5Cpi%20t%29%7D%20%3D%200.204525%5Cpi%5Ccos%7B%280.4545%5Cpi%20t%29%7D)
The rate of change of the brightness after t days is ![B^{\prime}(t) = 0.204525\pi\cos{(0.4545\pi t)}](https://tex.z-dn.net/?f=B%5E%7B%5Cprime%7D%28t%29%20%3D%200.204525%5Cpi%5Ccos%7B%280.4545%5Cpi%20t%29%7D)
B) Find the rate of increase after one day.
This is
. So
![B^{\prime}(1) = 0.204525\pi\cos{(0.4545\pi)} = 0.0915](https://tex.z-dn.net/?f=B%5E%7B%5Cprime%7D%281%29%20%3D%200.204525%5Cpi%5Ccos%7B%280.4545%5Cpi%29%7D%20%3D%200.0915)
The rate of increase after one day is of 0.0915.

Answer:
No . Natural numbers are a subset of whole number. Negative numbers are entire numbers but not natural. And any set that contains it. For example, the set {1, 2.3, 2.236067977} or {-79000, pi, 2.236067977, sin(47)} or all real numbers, etc
