Answer
Find out the what is the effective cost per year of the extended warranty .
To proof
As given
The extended warranty on a $960 dishwasher is 21% of the purchase price and lasts for eight years.
21% is written in the decimal form
= 0.21
effective cost for the extended warranty = 0.21 × 960
= $ 201.6
= $25.2
Therefore the
effective cost per year of the extended warranty be $25.2
Option (d) is correct .
Hence proved
Answer:
0.5
Step-by-step explanation:
The function is represented as y = f(x) =
Now, it is clear from the function given above that, for x = 0, y = f(x) = 10, and for x=1, f(x) = 5, and for x=2, f(x) = 2.5.
Therefore, the value of f(x) is multiplied each time by 0.5 for each unit increase in the value of x.
So, the multiplicative rate of change of the function is 0.5. (Answer)
