Answer:
If I'm not mistaken Od)-2x+70
Step-by-step explanation:
hi
f(x) = (x+9) (x-4)
if it's cross the x axis it's means f(x) = 0
(x+9) (x-4) = 0 means x+9 = 0 so x = -9 and x-4 = 0 so x = 4
answers f(x) = 0 for x = -9 and x = 4
Answer:
![f(x)=70(1.17)^x](https://tex.z-dn.net/?f=f%28x%29%3D70%281.17%29%5Ex)
Step-by-step explanation:
x is time in years
f(x) represent the average annual salary in thousand dollars
We are given
The average annual salary of the employees of a company in the Year 2005 was $70,000
We can use exponential formula
![f(x)=a(b)^x](https://tex.z-dn.net/?f=f%28x%29%3Da%28b%29%5Ex)
Since, time starts from 2005
So, at x=0 , f(x)=70
we can use it
![70=a(b)^0](https://tex.z-dn.net/?f=70%3Da%28b%29%5E0)
![a=70](https://tex.z-dn.net/?f=a%3D70)
in 2006 the average annual salary was $82,000
So, in x=2006-2005=1
f(x)=82
we can plug it and find b
![82=70(b)^1](https://tex.z-dn.net/?f=82%3D70%28b%29%5E1)
![b=\frac{41}{35}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B41%7D%7B35%7D)
![b=1.17](https://tex.z-dn.net/?f=b%3D1.17)
now, we can plug it back
and we get
![f(x)=70(1.17)^x](https://tex.z-dn.net/?f=f%28x%29%3D70%281.17%29%5Ex)
Answer: 6 1/15 inch
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Yuma: 2 2/3 inch of rain
</em>
- <em>Las Vegas: 4 1/5 inch of rain
</em>
So, to obtain the number of the two cities combined we simply have to add both values.
Mathematically speaking
2 2/3 + 4 1/15 = 2 10/15 + 4 1/15 = 6 1/15 inch
The 2 cities combined get an average of 6 1/15 inch of rain each year.
Feel free to ask for more if needed or if you did not understand something.
So you can solve this by drawing a digram. Draw each points and label all checkpoints. Study the drawing as long as you can to understand the situation. The question is asking for too much, so its a slippery slope.
