How are the two functions f(x) = 0.7(6)x and g(x) = 0.7(6)–x related to each other?
Harlamova29_29 [7]
The answer
f(x) = 0.7(6)x = <span>f(x) = 0.7(6)^x, and  </span><span>g(x) = 0.7(6)–x= </span>g(x) = 0.7(6)^-x=1/<span>0.7(6)^x
so </span>
g(x) =1/<span>0.7(6)^x=1 /</span><span><span>f(x)

</span> the relationship between f and g are </span>g(x) =1 /<span>f(x) or </span><span>g(x) . <span>f(x) = 1</span> </span>

Solve. Find all solutions in [0,2).5 secx cotx+5 secx+ cotx+1=0
Dmitrij [34]
\begin{gathered} 5sec(x)cot(x)+5sec(x)+cot(x)+1=0 \\ Factoring \\ (cot(x)+1)(5sec(x)+1)=0 \\ cot(x)+1=0 \\ cot(x)=-1 \\ x=cot^{-1}(1) \\ x=\frac{3\pi}{4} \\  \\ 5sec(x)+1=0 \\ 5sec(x)=-1 \\ sec(x)=\frac{-1}{5},\text{ there is no solution} \\ Hence \\ All\text{ solution are }\frac{3\pi}{4}+\pi n,\text{ where n=1,2,3...} \\  \\  \end{gathered}

Refer to your math writing journal file named "Lines and Angles." What real-world examples did you describe for the three ways i
Sav [38]

Answer:

  1. Railway lines are example of parallel lines
  2. The floor and the walls of a room are example of perpendicular lines
  3. Two roads crossing at a signal can be termed as example of intersecting lines

Step-by-step explanation:

The lines can be related in following three ways

  1. Lines can be parallel
  2. Lines can be perpendicular
  3. Lines can be intersecting at an angle other than 90.

Now three real life examples of above three scenarios are described below:

  1. Railway lines are example of parallel lines
  2. The floor and the walls of a room are example of perpendicular lines
  3. Two roads crossing at a signal can be termed as example of intersecting lines
