N 2008 price of houses were declining by 2% each year. If a house was purchased for $195,000, write the equation that models the situation.

p₁ = 0.98 p₀

p₂ = 0.98 p₁

Step-by-step explanation:

Given - N 2008 price of houses were declining by 2% each year.

             If a house was purchased for $195,000.

To find - Write the equation that models the situation.

Proof -

Let us assume that

p₀ = initial price of house

p₁ = price of house after 1 year

p₂ = price of house after 2 years

Now,

Given that, p₀ = $195,000

Then,

p₁ = p₀ - 2% p₀

   = p₀( 1 - 2%)

   = p₀ ( 98%)

⇒p₁ = 98% p₀

⇒p₁ = p₀

⇒p₁ = 0.98 p₀

Now,

Also p₂ = p₁ - 2% p₁

By doing the same process as above, we get

p₂ = 0.98 p₁

step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
