B). Cosine
Answer
The equation is already in slope intercept form so just graph it as you normally would.
Step-by-step explanation:
graph the -3x as a line the looks like this \ that goes through the +60. It should look like this
???/where is what located
we are given
![I=3.8 \times 10^6](https://tex.z-dn.net/?f=I%3D3.8%20%5Ctimes%2010%5E6)
![I_0=1](https://tex.z-dn.net/?f=I_0%3D1)
now, we can use formula
![R=log(\frac{I}{I_0} )](https://tex.z-dn.net/?f=R%3Dlog%28%5Cfrac%7BI%7D%7BI_0%7D%20%29)
now, we can plug these values
we get
![R=log(\frac{3.8 \times 10^6}{1} )](https://tex.z-dn.net/?f=R%3Dlog%28%5Cfrac%7B3.8%20%5Ctimes%2010%5E6%7D%7B1%7D%20%29)
............Answer
solution:
Since, it’s a standard cone opening up on the positive x – axis therefore,
X = √y²+z²
And because it has a vertex at (7,0,0)
Therefore the equation of surface is
X = 7 + √y²+z²
