A new car is purchased for 17900 dollars. The value of the car depreciates at 12.25%
1 answer:
Answer:
Therefore the value of the car after 10 year will be = $4,845.34
Step-by-step explanation:
A new car is purchased for $17900. the value of the car depreciates at 12.25% per year.
Since the value of the car depreciates therefore the amount of the car is
[ p = $17900, r = 12.25% and n =10 years]
= $ 4,845.34
Therefore the value of the car after 10 year will be = $4,845.34

Answer:
- there are 4 complex solutions
- 3 real zeros and 2 complex zeros
Step-by-step explanation:
1. Descarte's rule of signs tells you there are 0 positive real roots and 0 or 2 negative real roots. (for positive x, signs are ++++ so have no changes; for negative x, signs are ++-+, so have 2 changes.) A graph shows no real roots.
2. There are 3 sign changes in the given polynomial, so 3 or 1 positive real roots. When the sign of x is changed, there are 2 sign changes, so 0 or 2 negative real roots. A graph shows 2 negative and one positive real root (for a total of 3), so the remaining 2 roots are complex.
