Answer:
If you meant , then the answer is approximately 0.866.
If you meant , then the answer is approximately -2.909 which looks like what you meant based on the choices.
Step-by-step explanation:
First step is to get the exponential part by itself. The part that has the variable exponent which is the term.
To do this we need to subtract 4 on both sides:
Simplify:
The equivalent logarithmic form is:
I always say to myself the logarithm is the exponent that is how I know what to put opposite the side containing the log.
Anyways if you don't have options for computing in your calculator you need to use the change of base formula.
So
I don't see this as a choice so maybe you actually meant the following equation:
Let's see if this is the correct interpretation.
So the exponential part is already isolated.
So we just need to put in the equivalent logarithmic form:
Now we subtract 4 on both sides:
Again if you don't have the option for computing in your calculator, you will have to use the change of base formula:
Answer: First Question: True
Second Question: False
Third Question: False
Step-by-step explanation:
Based on the equations in the image, I used the substitution method.
First keep in mind that the given value is negative and that it is greater than or equal to whatever '<em>v</em>' is.
When solving for a variable in any equation, you do something to both sides in order to keep it equal. Here, <em>v</em> is being subtracted by 1.9; therefore we can add 1.9 to both sides in order to isolate <em />the variable.
Despite not needing a value for the question, it is worth noting that since this is an inequality, <em>v </em>can be any value from -6.4 to ∞ in order to make it true.
