The value of building in 2014 is 0.92 million.

The value of building in 2018 is 0.84 million.

Step-by-step explanation:

Consider the provided information.

An office building worth $1 million when completed in 2010.

That means the first ordered pair is (0, 1)

Here, 1 is the y intercept.

Here, 0 represents the building is 0 year old while 1 is the worth of building i.e 1 million.

It being depreciated linearly over 50 years and the scarp value is $0.

That means the second ordered pair is (50, 0)

Where, 50 represents, the building is 50 year old while 0 is the worth of building i.e 0 million.

Now use the slope formula:

$m = \frac{(y_2-y_1)}{(x_2-x_1)}$

$m = \frac{(0-1)}{(50-0)}$

$m = \frac{-1}{50}$

The slope intercept form is y=mx+c

Where m is slope and c is the y intercept.

We know slope of the line is -1/50 and y intercept is 1.

Thus, the slope intercept form of the line is:

$y= \frac{-1}{50}x+1$

Where, x is the time(in years) and y is the value of the building(in millions of dollars).

Now we want the book value of the building in 2014.

First find the value of x and substitute it in the above equation of line.

x=2014-2010=4

Substitute the value of x in $y= \frac{-1}{50}x+1$

$y= \frac{-1}{50}\times 4+1$

y= -0.08+1

y= 0.92

Thus, the value of building in 2014 is 0.92 million = 920 thousand dollars.

Now find the value in 2018.

First find the value of x and substitute it in the above equation of line.

x=2018-2010=8

Substitute the value of x in $y= \frac{-1}{50}x+1$

$y= \frac{-1}{50}\times 8+1$

y= -0.16+1

y= 0.84

Thus, the value of building in 2018 is 0.84 million = 840 thousand dollars.

Answer from: Quest

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

$\tan\left(x\right)=\frac{\left[altitude\right]}{\left[base\right]}=\frac{p}{r}$

$\tan\left(x\right)=\frac{p}{r}$

$\frac{p}{r}=tan(x)$

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
