In realistic world there are so many examples which use exponential and logarithmic functions.
Use of Logarithmic function
We can find use of logarithmic function in measuring earthquake (Richter Scale) , the brightness of stars , and chemistry(pH balance , measure of acidity and alkalinity)
For example:
In Richter Scale , a logarithmic function that is used to measure the magnitude of earthquake.
If A = measure of amplitude of earthquake wave.
= Amplitude of smallest detectable wave.
From this we can find R the Richter scale measure of magnitude of earthquake.
Use of Exponential Function:Exponential function may use in finding compound interest , population growth , radioactivity decay , etc.
For example :
As we know the formula for compound interest is
Where P is principal amount , r = rate of interest(decimal) , n is the number of compounding period , t is time.
For
Property of the logarithm:
So
Then
Answer:
A.) 1/2
B.)5/8
C.)1/4
D.)3/4
To find the fraction just count the number of figures total. This is the denominator of your fraction
NExt just count how many spaces are shaded and that number is your numerator
For example in A we see that there is 4 triangles total
Therefore our fraction currently is x/4
NeXT we see that there are 2 shaded in
This makes our fraction 2/4 which if simplified is 1/2
Step-by-step explanation:
<em><u>Answer:</u></em>
The answer is A) The y-intercept of function A is greater than the y-intercept of function B.
<em><u>Step-by-step explanation:</u></em>
We can see by graphing function A that the y-intercept (where the graph crosses the y-axis) is (0,3). For function B, we can see that the y-intercept is (0,2). Therefore, we know that 3 is greater than 2, so the y-intercept for function A is greater than that of function B. <em>I'll attach a photo of the first function graphed online.</em>
