Using exponential function concepts, it is found that the second function has a greater rate, as 0.8 > 0.2.
<h3>What is an exponential function?</h3>
It is modeled by:

In which:
- a is the initial value, that is, y when x = 0.
- b is the rate of change, as a decimal.
Function 1 is given by:

Hence the rate is b = 0.2.
Considering the values on the table, function 2 is given by:

Hence the rate is b = 0.8.
Hence, the second function has a greater rate, as 0.8 > 0.2.

Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the required lengths are not given.
I will use the following data set to answer the question.

First, is to determine the range of the dataset



Next, we will make use of 4 classes. So, we divide range by 10 to get the number of class. 10 represents the interval




<em>So, we use 4 classes</em>
Plot the frequency distribution table as follows:

<em>See attachment for histogram</em>
It is B. Because the 3$ doesn't have any variables and the 2 dollars is per hours so 2x
Frequency is the Number of Waves passing through a Point in One Second
Given : The Frequency of the Wave is : 700 Hz
Given : The Wavelength of the Wave is : 6 meter
⇒ In One second 700 waves of Wavelength 6 meter cross the point
⇒ In One second the First wave travels : 700 × 6 meters
⇒ In One second the First wave travels : 4200 meter
⇒ The Speed of the wave is : 4200 m/sec

recall that, log <--- with no apparent base, implies base10, so you can just plug that in your calculator
for the change of base rule, it doesn't really matter what base you use, so long is the same above and below, it just so happen, that we used base10 in this case, but could have been anything, same result.
