Answer:
Time taken n = 19 years (Approx)
Step-by-step explanation:
Given:
Amount of car P = $27,500
Decrease rate r = 15% = 0.15
Final amount A = $1,254
Find:
Time taken n
Computation:
A = P[1-r]ⁿ
1,254 = 27,500[1-0.15]ⁿ
0.0456 = [0.85]ⁿ
Time taken n = 19 years (Approx)
The answer is x=3. Work shown in the photo above!
Answer:

Step-by-step explanation:
The reason is because you don't know the Inital amount she bought and because she visits two days in a row you would multiply
If you would like to simplify this equation, the only thing that you can do is simplify the radical.

=

Since 3 appears twice, we can factor it out of the radical. This gives us our answer of:
Answer: If x is less than 0, 2 to the power of that negative x will be 1/2^x.
So, 1/2^x.
