A construction company purchased some equipment costing $300,000. The value of the equipment depreciates
Daniel [21]

Answer:

Cost of equipment after n years = 300000 x 0.86ⁿ

Step-by-step explanation:

A construction company purchased some equipment costing $300,000.

Price of equipment = 300000 $

The value of the equipment depreciates  (decreases) at a rate of 14% per year.

Let c(n) be the cost of equipment after n years.

\texttt{Cost of equipment after 1 year =}300000-\frac{14}{100}\times 300000=0.86^1\times 300000\$\\\\\texttt{Cost of equipment after 2 years =}0.86^2\times 300000\$\\\\\texttt{Cost of equipment after 3 years =}0.86^3\times 300000\$\\\\\texttt{Cost of equipment after n years =}0.86^n\times 300000\$

Cost of equipment after n years = 300000 x 0.86ⁿ

Answer:

1) \frac{1}{(x - 3)(x + 2)}  +  \frac{3}{(x + 2)(4 - x)}  +  \frac{2}{(x - 3)(x - 4)}  \\  \\  =  \frac{x - 4}{(x - 3)(x + 2)(x - 4)}  -  \frac{3(x -  3)}{(x - 4)(x + 2)(x - 3)} +  \frac{2(x + 2)}{(x + 2)(x - 3)(x - 4)} \\  \\  =  \frac{x - 4  - 3x + 9 + 2x + 4}{(x - 3)(x - 4)(x + 2)}  \\  \\  =  \frac{9}{(x  +  2)(x - 3)(x - 4)}

2) \frac{2}{(x - 2)(x - 3)}  +  \frac{2}{(x - 1)(3 - x)}  +  \frac{1}{(1 - x)(2 - x)}  \\  \\  =  \frac{2(x - 1)}{(x - 1)(x - 2)(x - 3)}  -  \frac{2(x - 2)}{(x - 1)(x - 2)(x - 3)} +  \frac{x - 3}{(x - 1)(x - 2)(x - 3)}  \\  \\  =  \frac{2x - 2 - 2x + 4 + x - 3}{(x - 1)(x  -2)(x - 3)}  \\  \\  =  \frac{x - 1}{(x - 1)(x - 2)(x - 3)}  \\  \\  =  \frac{1}{(x - 2)(x - 3)}

Anja collected data about the number of dogs 9th-grade students own. she created this histogram to represent the data and determ
igomit [66]

As the histogram is skewed to the right because there is less data on the right side. So, she is correct that is option D.

<h3>What is a histogram graph?</h3>

A histogram graph is a graphical representation of given data. It is a bar graph that represents a frequency distribution by rectangles separated from each other with equal spaces.

A graph shows several dogs labeled 0 to 2 on the horizontal axis and frequency on the vertical axis.

here, we can see from a given data that as the number of dogs increases the frequency on the vertical axis decreases. At 0 dogs the frequency is 20, at 1 dog the frequency is 15, At 2 dogs the frequency is 12.

The histogram is skewed to the right because there is less data on the right side as the frequency decreases.

Therefore, the histogram is skewed to the right because there is less data on the right side. So, she is correct that is option D.
