Answer:
The decay factor is 0.88.
Step-by-step explanation:
The general form of an exponential decay function is
Where, a is initial value and b is decay factor.
It is given a new truck that sells for $29,000 depreciates (decreases in value) 12% each year.
The initial value is $29,000 and decay factor is
The exponential function is
Therefore the decay factor is 0.88.
Answer:
2
Step-by-step explanation:
From the graph, we obtain the trigonometric function as:
The corresponding cosine function have equation.
This function is of the form:
where is the amplitude.
Therefore the amplitude is |2|=2
The third choice is correct
