Answer:
B. 7.3 years
Step-by-step explanation:
The question is wrong. The correct function is :
We have the function 
that represents the value of a piece of farm equipment after 
years.
This means that when 
its original value is :
Now we want to calculate approximately when will its value be half its original value. Then, we write :
is half of its original value. We need to find that satisfies the following equation :
Solving for :
⇒
Now we apply natural logarithm to each side of the equation :
![ln(0.5)=ln[(0.91)^{x}]](https://tex.z-dn.net/?f=ln%280.5%29%3Dln%5B%280.91%29%5E%7Bx%7D%5D)
Using logarithm properties :
⇒
![ln(0.5)=x[ln(0.91)]](https://tex.z-dn.net/?f=ln%280.5%29%3Dx%5Bln%280.91%29%5D)
⇒
≅ 
The correct option is B. 7.3 years
First, find the slope of this line, if possible. Recall that slope = m = rise / run.
We see that x does not change:
the distance from 2 to 2 is 0, and thus the slope of this line would be undefined, due to division by zero. Thus, the line is vertical. if it passes thru (2,3), then the equation of the line can be taken to be x=2.
Answer:
If written in Standard form this equation would be:
Now i graphed this equation in Desmos and here is what i got:
Hope this helps!
