A car purchased 2 years ago. It depreciates at 20% per annum. If its present value is Rs. 400000, find: i) its value after 2 years, ii) its value for which it was purchased 2 years ago.

It'll cost and will be purchased at R$256.000

Step-by-step explanation:

You have the value of 400.000

You pick this value and take out 20% (80.000)

It costs 320.000 now

You will repeat the process (you take out 64.000 this time)

It costs R$256.000 and will be purchased at this price

if you need just tell me and i will come to the rescue.

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).
