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%

<span>exchange rate is $1 for 3 pesos = 5 * 3 = 15 pesos
It would probably be 30 pesos - 5 * 30 = 150 pesos

Volume of a cone: 1/3

r²h
r is the radius (diameter ÷ 2) and h is the height.
Find the radius first using the diameter: 2

÷ 2 = 1.25
Now plug in the numbers into the formula.
1/3

1.25²10 = <span>16.4

The volume of the cone is 16.4 cubic feet.
