Answers
Step-by-step explanation:
[tex] ln( \frac{1}{4}k ) [/tex]
[tex] ln(k {}^{ - 2} ) [/tex]
[tex] - 2 ln(k) [/tex]
The simplified form of logarithm is [tex]ln(\frac{1}{4k}) = - ln(k) - 2ln(2)[/tex]
What is Logarithm?
The power to which a number must be increased in order to obtain another number is known as the Logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm
The properties of Logarithm are :
log A + log B = log ABlog A − log B = log A/Blog Aⁿ = n log AGiven data ,
The equation is
[tex]A = ln(\frac{1}{4k})[/tex]
Now , from the logarithm rule log A − log B = log A/B , we can simplify
[tex]ln(\frac{1}{4k}) = ln(1) - ln (4k)[/tex]
And , [tex]ln(1) = 0[/tex]
So ,
[tex]ln(\frac{1}{4k}) = - ln (4k)[/tex]
Now , from the logarithm rule log A + log B = log AB , we get
[tex]ln(\frac{1}{4k}) = - ( ln(k) + ln(4) )[/tex]
[tex]ln(\frac{1}{4k}) = - ln(k) - ln(4)[/tex]
And , [tex]ln(4) = 2 ln(2)[/tex]
So ,
[tex]ln(\frac{1}{4k}) = - ln(k) - 2ln(2)[/tex]
Hence , the simplified form of logarithm is [tex]ln(\frac{1}{4k}) = - ln(k) - 2ln(2)[/tex]

Find the volume of the sphere
Answers
Answer:
Formula: [tex]\frac{4}{3}\pi r^3[/tex]
Plug in values: radius = 9.3
Volume: 1072.476π cubic units
Step-by-step explanation:
The formula to find the volume of a sphere is [tex]\frac{4}{3}\pi r^3[/tex], where r = radius. In this case, we leave the volume of sphere in terms of pi.
The only value we can plug in is the radius. In this case, the radius is 9.3 units.Now, we can solve for the volume:

Suppose that I wrote 150 words of my English paper yesterday and today I begin typing at a rate of 35 words per minute. Is the total number of words typed a linear function of the number of minutes since I began typing today?
Answers
Explanation:
x = number of minutes
35x = number of extra words after x minutes
This is because you add on 35 words per minute (wpm). So for instance, after 10 minutes, you add on 35x = 35*10 = 350 more words.
This is on top of the initial 150 words you already wrote yesterday. So we add the 35x onto the 150 to get the expression 35x+150. This represents the number of words total from yesterday and today combined.
Saying y = 35x+150 shows we have a linear function of the form y = mx+b
m = 35 = slope
b = 150 = y intercept

x is any number on the top row,
