Given:
There are given that the parent functions as a cosine function:
Where,
The amplitude of the function is 9.
The vertical shift is 11 units down.
Explanation:
To find the cosine function, we need to see the standard form of the cosine function:
![f(x)=acos(bx+c)+d](https://tex.z-dn.net/?f=f%28x%29%3Dacos%28bx%2Bc%29%2Bd)
Where,
a is the amplitude of the function,
Now,
According to the question:
The amplitude of the function is 9, which means:
![f(x)=9cos(bx+c)+d](https://tex.z-dn.net/?f=f%28x%29%3D9cos%28bx%2Bc%29%2Bd)
The vertical shift is 11 units down, which means:
![f(x)=9cos(bx+c)-11](https://tex.z-dn.net/?f=f%28x%29%3D9cos%28bx%2Bc%29-11)
For period:
![\begin{gathered} f(x)=-9cos(\frac{12\pi}{7}x+0)-11 \\ f(x)=-9cos(\frac{12\pi}{7}x)-11 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20f%28x%29%3D-9cos%28%5Cfrac%7B12%5Cpi%7D%7B7%7Dx%2B0%29-11%20%5C%5C%20f%28x%29%3D-9cos%28%5Cfrac%7B12%5Cpi%7D%7B7%7Dx%29-11%20%5Cend%7Bgathered%7D)
Final answer:
Hence, the cosine function is shown below;
I believe the percent decrease is 20%
as when you multiply 65.5 by 20%
it gives you 13.1
when you minus 13.1 from 65.50
it gives you $52.4
He uses 1/5 OF 5/6 of a yard. That "of" is very important, because it indicates that, to find the answer, you multiply the two together.
That being said (1/5) times (5/6) =5/30, which can be reduced to 1/6 yds to make the frame
Answer:
Since we do not know the balance we should start with, a general answer:
![b_{new} = b_{old} + \sum_{i} d_{i} - \sum_{j} w_{j} \\](https://tex.z-dn.net/?f=b_%7Bnew%7D%20%3D%20b_%7Bold%7D%20%2B%20%5Csum_%7Bi%7D%20d_%7Bi%7D%20-%20%5Csum_%7Bj%7D%20w_%7Bj%7D%20%5C%5C)
598 - 47,27 = 550,73, assuming b_old was 0$ for your example
Step-by-step explanation:
b stands for balance (old - before any deposits or withdrawals, new after all done)
d for deposits
w for withdrawals
