Answer:
The correct option is C. The function is a stretch of an exponential decay function.
Step-by-step explanation:
The general form of an exponential function is
where, a is the initial value and b is the growth factor.
If b<1, then it represents a decay function and if b>1, then it represents a growth function.
Let k be a stretch and compression factor.
If k<1, then it represents vertical compression and if k>1, then it represents vertical stretch.
In third function
Therefore the function is a stretch of an exponential decay function.
Answer:
The correct answers are:
0.95g
g - 0.05g
(1 - 0.05)g
Step-by-step explanation:
Amount of last week's rain = g inches
this week = 5% decrease on last week's amount
5% of last week's amount = 5/100 × g = 0.05g
∴ This week's amount of rain = 0.05g decrease
∴ Amount of rain this week = (Amount of rain last week) - 0.05g
∴ Amount of rain this week = g - 0.05g
This can be simplified by factorizing the common term "g"
g - 0.05g = g(1 - 0.05) = 0.95g
Here is the answer for math problem
