![F=(\pm 4,0)](https://tex.z-dn.net/?f=F%3D%28%5Cpm%204%2C0%29)
![V=(\pm 5,0)](https://tex.z-dn.net/?f=V%3D%28%5Cpm%205%2C0%29)
Step-by-step explanation:
From the question we are told that:
The Equation
![\frac{x^2}{9}*\frac{y^2}{25}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2%7D%7B9%7D%2A%5Cfrac%7By%5E2%7D%7B25%7D)
Generally
From the Equation
![a^2=25](https://tex.z-dn.net/?f=a%5E2%3D25)
![a=5\\b^2=9\\b=3](https://tex.z-dn.net/?f=a%3D5%5C%5Cb%5E2%3D9%5C%5Cb%3D3)
Therefore
![c=\sqrt{a^2-b^2}](https://tex.z-dn.net/?f=c%3D%5Csqrt%7Ba%5E2-b%5E2%7D)
![c=\sqrt{25-9}](https://tex.z-dn.net/?f=c%3D%5Csqrt%7B25-9%7D)
![c=\sqrt{16}](https://tex.z-dn.net/?f=c%3D%5Csqrt%7B16%7D)
![c=4](https://tex.z-dn.net/?f=c%3D4)
Generally the equation for center is mathematically given by
![C=(h,k)](https://tex.z-dn.net/?f=C%3D%28h%2Ck%29)
![C=(0,0)](https://tex.z-dn.net/?f=C%3D%280%2C0%29)
Generally the equation for foci is mathematically given by
![F=(h,k \pm c,0)](https://tex.z-dn.net/?f=F%3D%28h%2Ck%20%5Cpm%20c%2C0%29)
![F=(\pm 4,0)](https://tex.z-dn.net/?f=F%3D%28%5Cpm%204%2C0%29)
Generally the equation for vertice is mathematically given by
![V=(h,k \pm a,0)](https://tex.z-dn.net/?f=V%3D%28h%2Ck%20%5Cpm%20a%2C0%29)
![V=(\pm 5,0)](https://tex.z-dn.net/?f=V%3D%28%5Cpm%205%2C0%29)

Answer:
i need a descrption of the work like why is the equation is what it is
Step-by-step explanation:
Answer:
10 gallons.
Step-by-step explanation:
A leaky faucet is losing water and;
filling a 7-gallon bucket every 21 hrs.
So 7 gallons of water are leaked in 21 hrs
We are to find the number of gallons that will be leaked in 30 hrs.
Cross-multiplying this gives;
= 10 gallons.
