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:
N/-2=-16
Aka
Negative number(n) is divided by negative two equals negative sixteen
Im pretty sure its (1, 4) if its wrong im so so sorry but I do think thats the awnser
Answer: (3,-2)
Step-by-step explanation:
new system:
add.
plug in -2 for y
system:
Draw the graph for each side, member, of the equation and see where the curves cross, are equal. The x values of these points, are the solutions to the equation.
