Well in order to write a percent as a decimal you need to move 2 spaces to the left, because the meaning of percent is " out of 100" so two decimal points are hundredths.

Example: 65% is 0.65

Percent means - Per Cent meaning - / 100 as Cent is a 100.

When converting to decimal, we divide the given percentage value by 100.

4% = 4/100 = 0.04.

You are dividig it by 100 and divide operation moves the decimal to the left and as 100 is having 2 zeroes, so point will move 2 positions to its left...

Office equipment was purchased for $20,000 and is assumed to have a scrap value of $2,000 after 10 years. If its value is deprec

boyakko [2]

According to the information given in the exercise:

- The office equipment was purchased for $20,000.

- The scrap value is assumed to be $2,000 after 10 years.

- -It's depreciated linearly from $20,000 to $2,000.

(a) The Slope-Intercept Form of the equation of a line is:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept.

Let be "V" the value (in dollars) and "t" the time (in years).

Analyzing the information given in the exercise, you can set up that the equation will have this form:

$V=mt+b$

Where "m" is the slope and "b" is the y-intercept.

Notice that you have these two points:

$\begin{gathered} (0,20000) \\ (10,2000) \end{gathered}$

Then, you can apply the formula for calculating the slope:

$m=\frac{y_2-y_1}{x_2-x_1_{}}$

You can say that:

$\begin{gathered} y_2=2000 \\ y_1=20000 \\ x_2=10 \\ x_1=0 \end{gathered}$

Substituting and evaluating, you get:

$m=\frac{2000-20000}{10-0}=\frac{-18000}{10}=-1800$

To find "b", you need to remember that the value of "x" is zero when the line intersects the y-axis. Therefore, knowing that one of the points is:

$(0,20000)$

You can determine that:

$b=20000$

Hence, the equation is:

$V=-1800t+20000$

(b) To find the value of the equipment after 6 years, you need to set up that:

$t=6$

Then, substituting this value into the equation and evaluating, you get:

$\begin{gathered} V=-1800(6)+20000 \\ V=9200 \end{gathered}$

Therefore, the answers are:

(a)

$V=-1800t+20000$

(b) $9,200

If h(x)=(fog)(x) and h(x) = sqrt x+5, find g(x) if f(x) = sqrtx+2

Katen [24]

Answer: The value of g(x) is x+3.

Step-by-step explanation:

Since we have given that

$h(x)=f\circ g(x)$

Here,

$h(x)=\sqrt{x+5}\\\\and\\\\f(x)=\sqrt{x+2}$

We need to find the value of g(x):

$f(x)=\sqrt{x+2}\\\\f(g(x))=\sqrt{g(x)+2}\\\\h(x)=\sqrt{g(x)+2}\\\\\sqrt{x+5}=\sqrt{g(x)+2}\\\\x+5=g(x)+2\\\\g(x)=x+5-2=x+3$

Hence, the value of g(x) is x+3.
