Answer: ![d=13.8](https://tex.z-dn.net/?f=d%3D13.8)
Step-by-step explanation:
A line that cuts a circle at two points is called "secant".
There is a theorem known as "Intersecting Secant Theorem". This is the theorem you need to use to find the value of "d".
According the Intersecting Secant Theorem:
![(14)(14+20)=(16)(16+d)\\(14)(34)=(16)(16+d)](https://tex.z-dn.net/?f=%2814%29%2814%2B20%29%3D%2816%29%2816%2Bd%29%5C%5C%2814%29%2834%29%3D%2816%29%2816%2Bd%29)
Having this expression, the next step is to solve for "d":
Use Distributive property:
![476=256+16d](https://tex.z-dn.net/?f=476%3D256%2B16d)
Subtract 256 from both sides:
![476-256=-256+256+16d](https://tex.z-dn.net/?f=476-256%3D-256%2B256%2B16d)
![220=16d](https://tex.z-dn.net/?f=220%3D16d)
Divide both sides by 16:
![\frac{220}{16}=\frac{16d}{16}\\\\13.75=d](https://tex.z-dn.net/?f=%5Cfrac%7B220%7D%7B16%7D%3D%5Cfrac%7B16d%7D%7B16%7D%5C%5C%5C%5C13.75%3Dd)
The value of "d" rounded to the nearest tenth is:
![d=13.8](https://tex.z-dn.net/?f=d%3D13.8)
Answer:
1
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
minus the variable, 4-1 is 3.
$20,000
25,000,000 x 0.0002 = 5,000
5,000 x $4.00= $20,000
