Depreciation is the decrease or loss in value of an item due to age, wear, or market conditions. We usually consider
depreciation on expensive items like cars. Businesses use depreciation as a loss when calculating their income and taxes.
One company buys a new bulldozer for $101250. The company depreciates the bulldozer linearly over its useful life of 15
years. Its salvage value at the end of 15 years is $15000.
A) Express the value of the bulldozer, V, as a function of how many years old it is, t. Make sure to use function notation.

B) The value of the bulldozer after 8 years is $
PLEASE HELP ASAP

Part A)

Part B)

Step-by-step explanation:

Part A) Express the value of the bulldozer, V, as a function of how many years old it is, t.

Let

V ----> the value of the bulldozer (dependent variable or output value)

t ----> the number of years (independent variable or input value)

we know that

The linear function in slope intercept form is equal to

we have the ordered pairs

(0,101,250) and (15,15,000)

Find the slope

The formula to calculate the slope between two points is equal to

substitute

----> is negative because is a decreasing function

The value of b is the initial value

so

substitute

Part B) The value of the bulldozer after 8 years is

For t=8 years

substitute the value of t in the linear equation

x+14

step-by-step explanation:

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.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
