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:

Step-by-step explanation:
I’m very confused
Personally, I did this in a kinda weird way but I think that it should be correct
-How I figured the answer out-
I took 11g and wrote 80% next to it, because after all it has 80% less fat than the regular cookie.
Then, I scaled it down to 10% by dividing by 8, which got me
1.375g = 10%
And finally, I multiplied by 10 to now have 100% (meaning, a regular serving size cookie) and be left with the result: 13.75g
-The answer-
13.75g (don't forget to write the units)
Have a great day :)
X^2+8x=10
X^2+8x-10=0
(X^2+8x+16-16)-10=0
(X^2+8x+16)-16-10
(X+4)^2-26
Hope this helps!
