An antique car costs $32,000 It gains 8% in value every year. How much will it be worth in 6 years?
1 answer:
Each year, it's value is 1.08 of the previous price, so the equation is
Using a calculator, you get that the answer is 50779.978. You must also round to the nearest hundredth because in our currency, cents are the smallest unit.
Therefore, an antique car that costs $32000 will be worth 50779.98 6 years after.

This is calculated as:
Solution:
As we know reference angle is smallest angle between terminal side and X axis.
As cosine 45 ° is always positive in first and fourth quadrant.
i.e CosФ, Cos (-Ф) or Cos(2π - Ф) have same value.
As, Cos 45°, Cos (-45°) or Cos ( 360° - 45°)= Cos 315°are same.
So, Angles that share the same Cosine value as Cos 45° have same terminal sides will be in Quadrant IV having value Either Cos (-45°) or Cos (315°).
Also, Cos 45° = Sin 45° or Sin 135° i.e terminal side in first Quadrant or second Quadrant.
