Step-by-step explanation:
Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
So,
⇒ 43° + 70° + x° = 180°
43° + 70° = 113°:
⇒ 113° + x° = 180°
Substracting 113° from both sides:
⇒ 113° - 113° + x° = 180° - 113°
113° - 113° = 0°:
⇒ x° = 180° - 113°
180° - 113° = 67°:
⇒ x° = 67°

An organization can purchase a bulk-mail permit for $190 per year. With the bulk-mail permit, each piece of mail, x, costs 27.6 cents to send. Without the permit, each piece of mail costs 44 cents to send. How many pieces of mail, x, would an organization need to send in a year to make it cheaper to use a bulk-mail permit
Answer:
1,159 pieces of mail
Step-by-step explanation:
From the information given, you can write an inequality that indicates that the price of sending each piece of mail without the permit is higher than the price of purchasing the bulk-mail permit and then, you can solve for x that is the number of pieces of mail:
0.44x>0.276x+190
0.44x-0.276x>190
0.164x>190
x>190/0.164
x>1,158.5
According to this, the organization needs to send 1,159 pieces of mail in a year to make it cheaper to use a bulk-mail permit.
What are the different volume methods(cylindrical, shell etc) and what are their formulas rotating around both x and y axis?
Answer:
For revolution about the y-axis:
shell: dV = 2π·x·(f2(x) -f1(x))·dxdisk: dV = π·(f2(y)^2 -f1(y)^2)·dyFor revolution about the x-axis, swap x and y.
Step-by-step explanation:
The methods for computing the volume of revolution of a plane figure are ...
cylindrical shelldiskThe name of the method describes the shape of the differential of volume.
__
Cylindrical shell
For revolution about the y-axis, the differential of volume is a cylindrical shell of radius x, thickness dx, and height y2 -y1, where y2 = f2(x) and y1 = f1(x). (y2 > y1) Integration is over x.
dV = 2π·x·(f2(x) -f1(x))·dx
For revolution about the x-axis, the variables x and y are interchanged.
__
Disk
For revolution about the y-axis, the differential of volume is a donut or disk of inner radius f1(y) = x1 and outer radius f2(y) = x2 (x1 ≤ x2). The thickness is dy. Integration is over y.
dV = π·(f2(y)^2 -f1(y)^2)·dy
For revolution about the x-axis, the variables x and y are interchanged.
__
The preferred method is the one that gives simple integrable functions over a single range of integration. For some geometries, the integration range must be split, because the shape of the differential volume cannot be described by a simple rectangle whose length is the difference of functions of the integration variable.
When the differential of volume can be drawn either way, the choice of methods may be arbitrary. I usually choose the method that gives the simplest integrand.
_____
Additional comment
When the axis of revolution is something other than a coordinate axis, the radius of revolution becomes a different function than a simple x (or y). For example, if the axis of revolution is x=a, the radius of the cylindrical shell will be a-x (for x ≤ a) or x-a (for a ≤ x).
Here's an example of the use of the disk method.

What are two ways can you write 4 - n as an algebraic expression?
Answer: 4 + (-n) and -n+4
==========================================================
Explanation:
Adding a negative is the same as subtracting. For example, 10-7 = 10+(-7)
So that's why 4-n is the same as 4 + (-n)
---------
Then we go from 4 + (-n) to -n+4 because we can add two items in any order.
Example: 2+3 = 3+2 = 5

Students are paired in teams for a group science project. The number of hours each student spends working on the group project are recorded on the bar chart below. If Paloma and Abdul are a team, and Ben and Min are a team, how many more hours did Paloma and Abdul spend working on the project combined than Ben and Min?
Answer:
Paloma and Abdul combined spent 4 hours more working on the project than Ben and Min combined.
Step-by-step explanation:
Note: This question is not complete as the bar chart is not included. The bar chart is therefore included before answering the question. Please, see the attached jpeg file for the bar chart.
The explanation to the answer is now given as follows:
From the bar chart, we have the number of hours each student spends working on the group project as follows:
Numbers of hours spent by Paloma = 21 hours
Numbers of hours spent by Adbul = 18 hours
Numbers of hours spent by Ben = 13 hours
Numbers of hours spent by Min = 22 hours
The number of hours each group spent working on the group project is calculated as follows:
Numbers of hours spent by Paloma and Abdul = Numbers of hours spent by Paloma + Numbers of hours spent by Paloma = 21 hours + 18 hours = 39 hours
Numbers of hours spent by Ben and Min = Numbers of hours spent by Ben + Numbers of hours spent by Min = 13 hours + 22 hours = 35 hours
Th number of hours Paloma and Abdul spend working on the project combined more than Ben and Min combined = Numbers of hours spent by Paloma and Abdul - Numbers of hours spent by Ben and Min = 39 hours - 35 hours = 4 hours
Therefore, Paloma and Abdul combined spent 4 hours more working on the project than Ben and Min combined.
y=c1e^x+c2e^−x is a two-parameter family of solutions of the second order differential equation y′′−y=0. Find a solution of the second order initial value problem with initial conditions y(−1)=3,y′(−1)=−3
The general form of a solution of the differential equation is already provided for us:
[tex]y(x) = c_1 \textrm{e}^x + c_2\textrm{e}^{-x},[/tex]
where [tex]c_1, c_2 \in \mathbb{R}[/tex]. We now want to find a solution [tex]y[/tex] such that [tex]y(-1)=3[/tex] and [tex]y'(-1)=-3[/tex]. Therefore, all we need to do is find the constants [tex]c_1[/tex] and [tex]c_2[/tex] that satisfy the initial conditions. For the first condition, we have:[tex]y(-1)=3 \iff c_1 \textrm{e}^{-1} + c_2 \textrm{e}^{-(-1)} = 3 \iff c_1\textrm{e}^{-1} + c_2\textrm{e} = 3.[/tex]
For the second condition, we need to find the derivative [tex]y'[/tex] first. In this case, we have:
[tex]y'(x) = \left(c_1\textrm{e}^x + c_2\textrm{e}^{-x}\right)' = c_1\textrm{e}^x - c_2\textrm{e}^{-x}.[/tex]
Therefore:
[tex]y'(-1) = -3 \iff c_1\textrm{e}^{-1} - c_2\textrm{e}^{-(-1)} = -3 \iff c_1\textrm{e}^{-1} - c_2\textrm{e} = -3.[/tex]
This means that we must solve the following system of equations:
[tex]\begin{cases}c_1\textrm{e}^{-1} + c_2\textrm{e} = 3 \\ c_1\textrm{e}^{-1} - c_2\textrm{e} = -3\end{cases}.[/tex]
If we add the equations above, we get:
[tex]\left(c_1\textrm{e}^{-1} + c_2\textrm{e}\right) + \left(c_1\textrm{e}^{-1} - c_2\textrm{e} \right) = 3-3 \iff 2c_1\textrm{e}^{-1} = 0 \iff c_1 = 0.[/tex]
If we now substitute [tex]c_1 = 0[/tex] into either of the equations in the system, we get:
[tex]c_2 \textrm{e} = 3 \iff c_2 = \dfrac{3}{\textrm{e}} = 3\textrm{e}^{-1.}[/tex]
This means that the solution obeying the initial conditions is:
[tex]\boxed{y(x) = 3\textrm{e}^{-1} \times \textrm{e}^{-x} = 3\textrm{e}^{-x-1}}.[/tex]
Indeed, we can see that:
[tex]y(-1) = 3\textrm{e}^{-(-1) -1} = 3\textrm{e}^{1-1} = 3\textrm{e}^0 = 3[/tex]
[tex]y'(x) =-3\textrm{e}^{-x-1} \implies y'(-1) = -3\textrm{e}^{-(-1)-1} = -3\textrm{e}^{1-1} = -3\textrm{e}^0 = -3,[/tex]
which do correspond to the desired initial conditions.
Order these numbers from least to greatest.

The width is to be 16 feet less than 4 times the height. Find the width and the height if the carpenter expects to use 26 feet of lumber to make it.
Answer:
w= 3 feet
h= 5 feet
Step-by-step explanation:
H=height; W=width=2H-7ft
W=2H-7ft
2H+4W=22ft Substitute for W
2H+4(2H-7ft)=22ft
2H+8H-28ft=22ft Add 28 ft to each side.
10H=50ft
H=5 ft ANSWER 1: The bookshelf is 5 feet high.
W=2H-7ft=2(5ft)-7ft=10ft-7ft=3ft
ANSWER 2: the bookshelf is 3 feet wide.
CHECK:
2H+4W=22ft
2(5ft)+4(3ft)=22ft
10ft+12ft=22ft
22ft=22ft

Step-by-step explanation:
15. If x=a Sin2t (I+Cos2t) and y=b Cos 2t (1-Cos2t) then find
dy/dx at =22/7*4
By the chain rule,
[tex]\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\mathrm dy}{\mathrm dt}\dfrac{\mathrm dt}{\mathrm dx}\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\frac{\mathrm dy}{\mathrm dt}}{\frac{\mathrm dx}{\mathrm dt}}[/tex]
It looks like we're given
[tex]\begin{cases}x=a\sin(2t)(1+\cos(2t))\\y=b\cos(2t)(1-\cos(2t))\end{cases}[/tex]
where a and b are presumably constant.
Recall that
[tex]\cos^2t=\dfrac{1+\cos(2t)}2[/tex]
[tex]\sin^2t=\dfrac{1-\cos(2t)}2[/tex]
so that
[tex]\begin{cases}x=2a\sin(2t)\cos^2t\\y=2b\cos(2t)\sin^2t\end{cases}[/tex]
Then we have
[tex]\dfrac{\mathrm dx}{\mathrm dt}=4a\cos(2t)\cos^2t-4a\sin(2t)\cos t\sin t[/tex]
[tex]\dfrac{\mathrm dy}{\mathrm dt}=-4b\sin(2t)\sin^2t+4b\cos(2t)\sin t\cos t[/tex]
[tex]\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{4b\cos(2t)\sin t\cos t-4b\sin(2t)\sin^2}{4a\cos(2t)\cos^2t-4a\sin(2t)\cos t\sin t}[/tex]
[tex]\implies\boxed{\dfrac{\mathrm dy}{\mathrm dx}=\dfrac ba\tan t}[/tex]
where the last reduction follows from dividing through everything by [tex]\cos(2t)\cos^2t[/tex] and simplifying.
I'm not sure at which point you're supposed to evaluate the derivative (22/7*4, as in 88/7? or something else?), so I'll leave that to you.
Let the graph of f(x) represent the cost in thousands of dollars to feed the zoo animals daily, where x is the number of animals measured in hundreds. What does the solution to the function (2, 8) represent?
a graph of a function that increases from the lower left, travels through an ordered pair labelled, 2, 8, and then increases toward the right
There are 800 animals, and the cost is $2,000 daily.
There are 8,000 animals, and the cost is $200 daily.
There are 200 animals, and the cost is $8,000 daily.
There are 2,000 animals, and the cost is $800 daily.
Answer: (C). There are 200 animals, and the cost is $8,000 daily.
Step-by-step explanation: We already know (x) is the number of animals measured in hundreds and it would go on the x axis. And that would mean that (f) is going to be on the y axis. Go over on the x axis 2 then for the y axis go up 8 on the y axis and you would get (2,8)= (200 animals, $8,000 a day)
There are 200 animals, and the cost is $8,000 daily

X
A rectangular painting measures 10 inches by
16 inches and contains a frame of uniform
width around the four edges. The perimeter of
the rectangle formed by the painting and its
frame is 76 inches. Determine the width of the
frame.
X
What is the width of the frame?
inch(es)
Answer:
The width of the frame is 3 inches
Step-by-step explanation:
We are told that the inner rectangle is 10 inches by 16 inches.
It means the outer rectangle has to be (L = 10 + 2x) by (W = 16 + 2x),
Where x represents the width of the frame.
The perimeter of the frame is given by; p = 2L + 2W
p = 2(10+2x) + 2(16+2x)
We are given perimeter, P = 76
Thus;
2(10 + 2x) + 2(16 + 2x) = 76
Divide both sides by 2 to give;
(10+2x) + (16+2x) = 38
(10+16) + (2x+2x) = 38
4x = 38 - 26
4x = 12
x = 12/4 = 3
The width of the frame is x = 3 inches

Answer:
f'(1)=150ln(1.5)
Step-by-step explanation:
I'm not sure why you would need a table since the limit definition of a derivative (from what I'm remembering) gives you the exact formula anyway... so hopefully this at least helps point you in the right direction.
My work is in the attachment but I do want to address the elephant on the blackboard real quick.
You'll see that I got to the point where I isolated the h's and just stated the limit equaled the natural log of something out of nowhere. This is because, as far as I know, the way to show that is true is through the use of limits going to infinity. And I'm assuming that you haven't even begun to talk about infinite limits yet, so I'm gonna ask you to just trust that that is true. (Also the proof is a little long and could be a question on it's own tbh. There are actually other methods to take this derivative but they involve knowing other derivatives and that kinda spoils a question of this caliber.)

Online entertainment streaming services have gained in popularity in recent years as an alternative to traditional television. One such company has seen steady growth in each period of 3 months, called a quarter, over the past 4 years. The scatterplot shows the relationship between the number of quarters since January 2014 and the log of the number of members to the streaming service. A least-squares equation that summarizes this relationship is Log subscribers hat = 0.026 (quarters) minus 1.299. A graph titled log (subscribers) versus quarters since January 2011 has quarters since January 2011 on the x-axis, and log (subscribers) on the y-axis. Points form a line with positive slope. A graph titled log (subscribers) versus quarters since January 2011 has quarters since January 2011 on the x-axis, and residual on the y-axis. Points are scattered throughout the graph. Based on the scatterplot and residual plot, what type of model is appropriate for comparing time and subscribers? A linear model is appropriate because the residual plot shows a random scatter of points. A logarithmic model is appropriate because the log of the number of subscribers was taken. A power model is appropriate because the relationship between period and the log of subscribers is roughly linear. An exponential model is appropriate because the relationship between period and the log of subscribers is roughly linear and the residual plot shows no distinct pattern.
