Answer:
![\displaystyle y = 7\sin(9\pi(x + {1}/{4}) )](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20y%20%3D%207%5Csin%289%5Cpi%28x%20%2B%20%20%20%7B1%7D%2F%7B4%7D%29%20%29)
Step-by-step explanation:
we are given
- Amplitude:7
- Period:9π
- Phrase shift:¼
remember that,
![\displaystyle y = A \sin(B(x + C) )+ D](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20y%20%3D%20A%20%5Csin%28B%28x%20%2B%20C%29%20%29%2B%20D)
where A is the Amplitude
B is the Period
C is the Phase shift
D is the vertical shift
note that, since D isn't given we'll take it 0
altogether substitute:
![\displaystyle y = 7\sin(9\pi(x + {}^{1}/_{4}) )+ 0](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20y%20%3D%207%5Csin%289%5Cpi%28x%20%2B%20%20%20%7B%7D%5E%7B1%7D%2F_%7B4%7D%29%20%29%2B%200)
hence,
our equation is
![\displaystyle y = 7\sin(9\pi(x + {}^{1}/_{4}) )](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20y%20%3D%207%5Csin%289%5Cpi%28x%20%2B%20%20%20%7B%7D%5E%7B1%7D%2F_%7B4%7D%29%20%29)
and we are done!

Answer:
35:14
Step-by-step explanation:
The ratio is 5:2.
The smaller number is 14, which replaces the 2. First, find the factor you used to get to 14. To do so, divide 14 by the smaller ratio number, 2:
14/2 = 7
Now, multiply 7 to the other side of the ratio:
5 x 7 = 35
If 5:2 ∴ 35:14
35:14 is your ratio.
