[tex]f(x) = {sec}^{ - 1} x \\ let \: y = {sec}^{ - 1} x \rightarrow \: x = sec \: y\\ \frac{dx}{dx} = \frac{d(sec \: y)}{dx} \\ 1 = \frac{d(sec \: y)}{dx} \times \frac{dy}{dy} \\ 1 = \frac{d(sec \: y)}{dy} \times \frac{dy}{dx} \\1 = tan \: y.sec \: y. \frac{dy}{dx} \\ \frac{dy}{dx} = \frac{1}{tan \: y.sec \: y} \\ \frac{dy}{dx} = \frac{1}{ \sqrt{( {sec}^{2} \: y - 1}) .sec \: y} \\ \frac{dy}{dx} = \frac{1}{ |x | \sqrt{ {x }^{2} - 1} } \\ \therefore \frac{d( {sec}^{ - 1}x) }{dx} = \frac{1}{ |x | \sqrt{ {x }^{2} - 1} } \\ \frac{d( {sec}^{ - 1}5x) }{dx} = \frac{1}{ |5x | \sqrt{25 {x }^{2} - 1} }\\\\y=arccos(\frac{1}{x})\Rightarrow cosy=\frac{1}{x}\\x=secy\Rightarrow y=arcsecx\\\therefore \frac{d( {sec}^{ - 1}x) }{dx} = \frac{1}{ |x | \sqrt{ {x }^{2} - 1} }[/tex]

What’s an equivalent fractions for 6/8 with a 20 as the new denominator
Answer:
15/20
Step-by-step explanation:
Divide your denominator by your previous/compared denominator (20/8) to find the number as your numerator. Take the found numerator (2.5) and multiply it times the compared numerator (2.5 x 6) giving your 15/20.

How much will nick and Adam weigh?
Answer:
181 pounds
Step-by-step explanation:
You have already got the equation and solution which is great! The next step is simply a matter of replacing "x" with "7", because you know x=7.
After doing this, you will be left with the equation 160+3*7=195-2*7. We will look at the first part of the equation first. Using the rules of BIDMAS, you can calculate 3*7=21 and then 160+21=181. 181 is your final answer.
You can check that this is right by calculating the second part of the equation, and once done you should be left with 181. Again, using BIDMAS, you need to do 2*7=14 then 195-14=181. Now we know that everything is correct.

Answer: 8p + -4p = 2p + 6
Combine like terms: 8p + -4p = 4p
4p = 2p + 6
Reorder the terms:
4p = 6 + 2p
Solving
4p = 6 + 2p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-2p' to each side of the equation.
4p + -2p = 6 + 2p + -2p
Combine like terms: 4p + -2p = 2p
2p = 6 + 2p + -2p
Combine like terms: 2p + -2p = 0
2p = 6 + 0
2p = 6
Divide each side by '2'.
p = 3
Simplifying
p = 3

Write the slope-intercept equation of the line passing through (3.5) and (10.-7). Do not give decimals in your answer.
Answer:
Answer:
y = -12/7x + 71/7
Step-by-step explanation:
y2 - y1 / x2 - x1
-7 - 5 / 10 - 3
-12/7
y = -12/7x + b
5 = -12/7(3) + b
5 = -36/7 + b
71/7 = b

Find the slope and intercepts of 3x + 4y = 12. Sketch a graph.
The slope of 3x + 4y = 12 is m = -3/4
To get the slope, you must use the slope-intercept form y = mx + b to find the slope.
The x-intercept of 3x + 4y = 12 are located at: (4,0)
To find the x-intercept, you must substitute in 0 for y and solve for x.
The y-intercept of 3x + 4y = 12 are located at: (0,3)
To find the y-intercept, you must substitute in 0 for x and solve for y.
Please view the graph attached below that has the slope and intercepts of 3x + 4y = 12 sketched.

Step-by-step explanation:
hannah and mallory are selling boxes of cookies for a school fundraiser. each box costs the same amount. hannah sells 14 boxes. mallory sells 22 boxes. mallory's neighbor makes a $6 donation without buying any cookies. together, hannah and mallory raise $141. write ans solve an equation to find out how much each box of cookies costs. how much does hannah raise? how much does mallory raise?
The cost per box of cookies is $3.75
The total amount Hannah raised from the sales of cookies is $52.50
The total amount Mallory raised from the sales of cookies and donations is $88.50
In order to determine the cost per box of cookies, take the following steps:
The first step is to determine the total sum of the boxes sold by Hannah and Mallory
Sum of the boxes sold = 14 + 22 = 36 boxes
36 boxes were sold by Hannah and Mallory
The second step is to determine the total cost of the 36 boxes sold.
Total cost of 36 boxes = total amount raised - donation
$141 - $6 = $135
The third step is to determine the total cost of each box
cost of one box = total cost of 36 boxes / total number of boxes
135 / 36 = $3.75
The total amount Hannah raised = cost per box x number of boxes she sold
14 x $3.75 = $52.50
The total amount Mallory raised = amount raised from the sale of cookies + donation
amount raised from sales = cost per box x number of boxes she sold
22 x $3.75 = $82.50
Total amount = $82.50 + $6 = $88.50

A jar contains 2000 marbles. If 61.5% of them are red, 27.5% are white, and 10% of them are blue, how many marbles are neither red, white, or blue?
Answer:
1 percent, or 20 marbles
Step-by-step explanation:
add all the other percentages and it sums up to 99%. and the other one percent of the marbles is 20.
Answer:
20 marbles
Step-by-step explanation:
61.5 + 27.5 + 10 = 99
this means 1% are neither red, white or blue
1% of 2000 is 20

mrs. jenningswants to take her kids on a field trip to the musem. the bus cost a total 100 and the meusem will charge 2 per student. what is the maximum number od students that mrs. jennings cantake to the meusem without exceeding her budget of 150
On a budget of $150, Mrs. Jennings will only be able to take 25 kids to the museum.
Mrs. Jennings has $150 in total and has to spend it on the bus and getting the kids into the museum.
After she spends on the bus, she will be left with:
= Budget - Cost of bus
= 150 - 100
= $50
She then spends $2 per kid. The total number of kids she can bring into the museum is:
= Amount remaining/ Cost per kid
= 50 / 2
= 25 kids
In conclusion, she can only take 25 kids.

Hi there!
What we need to know:
The three main trigonometric ratios are sine, cosine and tangent:
[tex]\displaystyle sin\theta=\frac{opposite}{hypotenuse}[/tex] [tex]\displaystyle cos\theta=\frac{adjacent}{hypotenuse}[/tex] [tex]\displaystyle tan\theta=\frac{opposite}{adjacent}[/tex]
"Opposite" refers to the side opposite the angle that is not the hypotenuse.
"Hypotenuse" refers to the side opposite the right angle of a right triangle.
"Adjacent" refers to the side next to the angle that is not the hypotenuse.
"θ" is read as "theta". It just represents the angle.
Keep in mind that these three ratios only apply to right triangles.
You can use the mnemonic "soh-cah-toa" to help you remember these ratios.
First question
For the first question, we're given the angle with a measure of 56 degrees and the length of the hypotenuse. We must calculate a, which represents the side adjacent to the given angle.
Given the hypotenuse and the adjacent side, we know that we must use the cosine ratio:
[tex]\displaystyle cos\theta=\frac{adjacent}{hypotenuse}[/tex]
Plug in the given information:
[tex]\displaystyle cos56=\frac{a}{13}[/tex]
Isolate a by multiplying both sides by 13:
[tex]13\displaystyle cos56=a[/tex]
Solve using a calculator:
[tex]a=7.3[/tex]
Therefore, a is equal to 7.3 when rounded to 1 decimal place.
Other information you will need to know:
In the above question, we needed to solve for a side. But what if we were given two sides and we needed to solve for an angle? For example:
[tex]\displaystyle sin\theta=\frac{5}{8}[/tex]
In this case, we will use the inverse sine ratio:
[tex]\displaystyle \theta=sin^-^1(\frac{5}{8})[/tex]
Solve using a calculator:
[tex]\displaystyle \theta=39[/tex]
Therefore, the angle would equal approximately 39 degrees.
I hope this helps!
