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:
3. isosceles, acute
5. scalene, obtuse
Step-by-step explanation:
3. Two (and only two) sides are the same length (and their opposite angles are the same measure), so the triangle is isosceles. All angles are less than 90°, so the triangle is acute.
__
5. All angles have different measures, so the triangle is scalene. The largest angle is greater than 90°, so the triangle is obtuse.
40 it's the same angle as angle A rotation doesn't change anything
Answer:
27 1/4
Step-by-step explanation:
Answer:
g=28, that may not be how the teacher would want you to show your work, but that's how I find the answer!
Step-by-step explanation:
6-3=3
31-3=28
28=g
So therefore 28+6-3=31
