Question
a) What is the decay factor?
b) What is the percent decrease?
c) Estimate the number of black and white TV's sold in 1999.
Answer:
a. Decay factor = 0.85
b. Percent decrease = 15%
c. 19.363 million TVs were sold
Step-by-step explanation:
Given
Solving (a): The decay factor
An exponential function has the form
Where b is:
By comparison:
Solving (b): Percentage decrease:
Percentage decrease P is calculated as follows:
Substitute 0.85 for b
Convert to percentage
Solving (c): TVs sold in 1999
First, we need to determine the value of t for 1999
In 1997, t= 0
In 1998, t= 1
In 1999, t= 2
So, we substitute 2 for t in:
Inequalities are used to represent unequal expressions
The solution to the system of inequalities is (-1,1)
<h3>How to determine the solution</h3>The system of inequalities is given as:
y > x + 2 and
y < 2x + 3
To do this, we start by plotting the graphs of the two inequalities
y > x + 2 and y < 2x + 3
See attachment for the graph
From the attached graph, both lines meet at (-1,1)
Hence, the solution to the system of inequalities is (-1,1)
