Answer: The rate of change in the value of the guitar is modeled by 0.95, which represents a decrease of 5% per year.
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential decay function:
A = P (1 - r) t
Where:
p = original price
r = decrease rate (decimal form)
t= years
A = price after t years
Replacing with the values given:
A(t)=145(0.95)t.
Where
0.95 = 1-r
0.95-1 = r
-0.05 =-r
0.05 =r
Converting to percentage form:
0.05 x 100 = 5%

Answer:
Option B.
Step-by-step explanation:
If a quadratic equation is defined as 
, the by quadratic formula
Consider the given equation is
We need to find the value of x.
Add 96 on both sides.
Here, a=1, b=14 and c=113. Using quadratic formula we get
The value of x are x=-7 + 8i and x=-7 - 8i.
Therefore, the correct option is B.
