Step-by-step explanation:
Given that,
Diameter of the Cylindrical tank, d = 60 ft Height of the Cylindrical tank, h = 20 ft Radius of the Cylindrical tank, r = 30ft.[tex] \: [/tex]
To Find:
Area of the Cylindrical tank to be painted.[tex] \: [/tex]
Solution:
Area of Cylindrical tank to be painted = CSA of the Cylindrical tank + Area of the circle
[tex] \star \quad{ \boxed{ \green{CSA_{(Cylinder)} = 2 \pi r h }}} \quad \star[/tex]
[tex]\star \quad{ \boxed{ \green{Area_{(Circle)} = \pi {r}^{2} }}} \quad \star[/tex]
[tex] \longrightarrow \: 2\pi rh \: + \pi {r}^{2} [/tex]
[tex]\longrightarrow \: \pi r(2h + r)[/tex]
[tex]\longrightarrow \: \frac{22}{7} \times 30 \times(2\times20+30) [/tex]
[tex]\longrightarrow \: \frac{660}{7} \times (40 + 30)[/tex]
[tex]\longrightarrow \: \frac{660}{7} \times 70 [/tex]
[tex]\longrightarrow \: 660 \times 10[/tex]
[tex]\longrightarrow \: 6600 {ft.}^{2} [/tex]
Hence, Area of the Cylindrical tank to be painted is 6600ft.²

Hey there!
These are the 2 kinds of sequences:
Arithmetic sequence. This is where we use addition/subtraction in order to get the next term.Geometric sequence. This is where we use multiplication/division in order to get the next term.Let's check the given sequence:
15, 12, 9, 6...
Do we use addition, subtraction, multiplication or division?
Well, we definitely do not multiply or divide anything here, so we have an arithmetic sequence.
Do we use addition or subtraction?
Well, let's take another look at our sequence.

Find the volume of the sphere
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:
[tex]\frac{4}{3} *9.3^3 * \pi[/tex] [tex]\frac{4}{3} * 804.357 * \pi[/tex] [tex]1072.476 * \pi[/tex] [tex]1072.476\pi[/tex]It costs 30 dollars per month for a cell phone plus 10 dollars for every GB of data.Which expression can be used to represent the cost of a cell phone bill when x is the number of GB of data used?

Answer:
Step-by-step explanation:
The Value of Y is 3 MORE than X.
For example, Because the equation is x+3=y
x is any number on the top row,
y is any number on the bottom row,
Meaning 1 + 3 = 4 Because 1 is on the x row, and 4 is on the y row.
You find the number you want to try and do x+3=y
Anyway answer is at the top.
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?
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

Expand the logarithm as much as possible. Rewrite the expression as a sum, difference, or product of logs.
ln(1/4k)
Enclose arguments of functions in parentheses and include a multiplication sign between terms. For example, c*ln(h).
ln(1/4k)=
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]
