If vector AB = i+7j-2k and B is point (7,4,4). Find A.
Answer:
A is point ( 6, -3, 6)
Step-by-step explanation:
Here in this question, we are concerned with finding the coordinates of point A.
Since we do not know the coordinates of point A, let’s represent them as (x,y,z)
By vector properties; Mathematically ;
AB = (7,4,4) - (x , y, z)
Thus; AB = (7-x)i + (4-y)j + (4-z)k
From the question, we are told that AB is also i + 7j -2k
By comparison;
(7-x)i = i
7-x = 1
x = 7-1
x = 6
(4-y)j = 7j
4-y = 7
4-7 = y
y = -3
and lastly
(4-z)k = -2k
4-z = -2
4 + 2 = z
z = 6
So the coordinates of A are (6, -3, 6)
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
please help me with this problem thanks
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
Is the given number a solution of the equation?
8=2+3; 10
Answer:
No.
Step-by-step explanation:
8 doesn't equal 0 on the very right, which means it's not a solution to the equation. So therefore, it is false based on the equation.
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.

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.
Answer:
D
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.
The measures of the three angles of a triangle are 43°, 70°, and x°. What is the value of x?
Answer:
37
Step-by-step explanation:
Answer:
[tex] \boxed{\sf x\degree = 67\degree} [/tex]
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°
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.

A bookcase is to have 4 shelves including the top as pictured below.
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

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
please answer or i move down grade again
Answer:
x is a 33° angle
Step-by-step explanation:
The two angles are supplementary meaning the measure of both angles adds up to 180°. You can tell they are supplementary because the angle is a straight line. so all you need to do is subtact 147 from. 180 to get the measure of x .
Answer:
x+147=180 ( sum of supplementary angle)
or, x = 180-147
or, x = 33
so the value of x is 33°
