Answer:
Step-by-step explanation:
Let's get this in a form we can better recognize. we'll rearrange it until we have y by itself.
x^2 + xy = 1
xy = 1 - x^2
y = 1/x - x
There, much better. Now, just looking at the graph you can tell there's no symmetry along the x or y axis. If you do not know how to check for symmetry along x=y or origin symmetry let me know. But checking for those does show that there is no symmetry along y = x but there is origin symmetry.
To determine that you just make all x and ys negative, and then see if you can get back to the original. Again, let me know if you don't get determining symmetry through algebra and I'd be happy to explain each of the variations; x ais, y axis, y=x and origin.

The volume of an open-top rectangular box is 4500 cc (cubic centimeters). The length of the rectangular base of the box is twice the width. What height will make the surface area as small as possible?
Answer:
The height that make the surface area as small as possible is 10 cm
Step-by-step explanation:
Let
L -----> the length of the base of the box
W -----> the width of the base of the box
H ----> the height of the box
we know that
The volume of the box is equal to
[tex]V=LWH[/tex]
we have
[tex]V=4,500\ cm^3[/tex]
so
[tex]4,500=LWH[/tex] ----> equation A
[tex]L=2W[/tex] ------> equation B
substitute equation B in equation A
[tex]4,500=(2W)WH[/tex]
[tex]4,500=2W^2H[/tex]
Solve for H
[tex]H=\frac{2,250}{W^{2}}[/tex] -----> equation C
The surface area of a open box is equal to
[tex]SA=2(L+W)H+LW[/tex] ----> equation D
Substitute equation B and equation C in equation D
[tex]SA=2(2W+W)(\frac{2,250}{W^{2}})+(2W)W[/tex]
[tex]SA=6W(\frac{2,250}{W^{2}})+2W^2[/tex]
[tex]SA=6(\frac{2,250}{W})+2W^2[/tex]
[tex]SA=\frac{13,500}{W}+2W^2[/tex]
Convert to function notation
[tex]f(W)=\frac{13,500}{W}+2W^2[/tex]
Find the derivative
[tex]f'(W)=-\frac{13,500}{W^2}+4W[/tex]
set equal to zero
[tex]f'(W)=0[/tex]
[tex]0=-\frac{13,500}{W^2}+4W[/tex]
Solve for W
[tex]\frac{13,500}{W^2}=4W[/tex]
[tex]W^3=\frac{13,500}{4}[/tex]
[tex]W=15\ cm[/tex]
Find the value of L (equation B)
[tex]L=2(15)=30\ cm[/tex]
Find the value of H (equation C)
[tex]H=\frac{2,250}{15^{2}}=10\ cm[/tex]
therefore
The height that make the surface area as small as possible is 10 cm
Describe the line segments. the cut sides of a wedge of apple pie: a) parallel b) intersecting c) skew
Answer:
They are intersecting line segments ⇒ answer b
Step-by-step explanation:
* Lets explain the types of the lines
- Parallel lines lie in the same plane and never intersect each other
- Intersecting lines are lines that meet each other in exactly one point
- Skew lines are lines that are in different planes and never intersect
* Now lets solve the problem
- The line segments that cut sides of a wedge of apple pie
∵ The wage of apple pie could represent a plane
∵ The line segments cut the sides of the wedge
∴ The lines are in the same plane
∵ Skew lines are in different planes and never intersect
∴ The lines can not be skew
∵ The line segments that cut sides of the wage must be intersected
at exactly one point
∵ Parallel lines never intersected
∴ The lines can not be parallel lines
∴ They are intersecting line segments

Answer:
y = [tex]\frac{1}{2}[/tex] x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is

Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (4, 3)
m= [tex]\frac{3-1}{4-0}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]

Your friend said that there are exactly 12 different pairs of numbers with a difference of 12 and that he had found them all. How would you respond to him?
Answer:
See explanation
Step-by-step explanation:
I wouls say to my friend that he is incorrect, because there are infinitely many pairs of numbers with a difference of 12.
For example,
[tex]13-1=12\\ 14-2=12\\15-3=12\\16-4=12\\...[/tex]
Here we can increase the first and the second number by 1 and get their difference equal to 12 after this operation.
The same is possible with negative numbers:
[tex]-1-(-13)=12\\ -2-(-14)=12\\-3-(-15)=12\\ ...[/tex]
Actuall, we can do this with decimals too
[tex]12.5-0.5=12\\ \\13.4-1.4=12\\ \\12\dfrac{1}{8}-\dfrac{1}{8}=12\\...[/tex]
Such pairs of numbers are infinitely many (because there are infinitely many real numbers) and we cannot find all possible numbers with difference of 12.

Paula knits hats. The number of hats h she can knit varies directly with the amount of yarn (y) in yards she has. The constant of proportionality is 42. H = 42y. What does the constant of proportionality, 42, represent in this problem?
- answer correctly
Answer:
42 = the number of hats Paula can knit from one yard of yarn
Step-by-step explanation:
The way this problem is written, the constant 42 is the multiplier of yards to get hats. That is, it has units of hats per yard, so represents the number of hats that can be knit from 1 yard of yarn.
_____
Comment on the problem
It seems more likely that the proportion should be written as ...
y = 42h
or
h = y/42
Then the constant would be the number of yards of yarn required for each hat.
A rock is thrown at a window that is located 18.0 m above the ground. The rock is thrown at an angle of 40.0° above horizontal. The rock is thrown from a height of 2.00 m above the ground with a speed of 30.0 m/s and experiences no appreciable air resistance. If the rock strikes the window on its upward trajectory, from what horizontal distance from the window was it released?
Answer:
27.32 m
Step-by-step explanation:
We are given that
Height of window from the ground=18 m
Height of rock form the ground=2 m
Speed of thrown rock=30 m/s
We have to find the horizontal distance from the window from which rock was release.
Difference between window and rock=18-2=16 m
Initial vertical velocity component=[tex]30sin40^{\circ}=19.28 [/tex]m/s
Initial horizontal velocity component=[tex]30cos 40^{\circ}=22.98 m/s[/tex]
If the rock is reached to maximum height
Then, maximum height=[tex]\frac{v^2}{2g}=\frac{(19.28)^2}{2\times 9.8}=18.9731 m[/tex]
Time taken by rock to reach maximum height=[tex]\frac{v}{g}=\frac{19.28}{9.8}=1.96775 s[/tex]
Distance between window and maximum height at which rock reached=18.9731-16=2.973 m
Time to drop 2.973 m=[tex]\sqrt{\frac{2h}{g}}=\sqrt{\frac{2\cdot 2.973}{9.8}}=0.77893 s[/tex]
Time to be at 16 m=1.96775-0.77893=1.189 s
Horizontal distance=[tex]1.189\times 22.98=27.32 m[/tex]
Hence, horizontal distance of rock from the window from which rock was released=27.32 m
The rock was released approximately 71.1 meters horizontally from the window. This calculation is based on the rock's initial speed of 30.0 m/s, launch angle of 40.0°, and the fact that it struck the window on its upward trajectory with no air resistance.
To solve this problem, we can use the kinematic equations of motion. We need to find the horizontal distance the rock was released from the window.
1. First, we can find the time it takes for the rock to reach its maximum height. We can use the following kinematic equation:
[tex]\[v_y = u_y + at\][/tex]
Where:
- [tex]\(v_y\)[/tex] is the final vertical velocity (0 m/s at the maximum height),
- [tex]\(u_y\)[/tex] is the initial vertical velocity (30.0 m/s, since it's thrown vertically),
- \(a\) is the vertical acceleration due to gravity (-9.81 m/s²),
- \(t\) is the time.
Rearrange the equation to solve for t:
[tex]\[0 = 30 - 9.81t\]\\\\[/tex]
[tex]\[t = \frac{30}{9.81} \approx 3.06 \, \text{s}\][/tex]
2. Now, we can find the horizontal distance using the horizontal motion equation:
[tex]\[d_x = u_x \cdot t\][/tex]
Where:
- [tex]\(d_x\)[/tex] is the horizontal distance we want to find.
- [tex]\(u_x\)[/tex] is the horizontal component of the initial velocity
[tex](30.0 m/s * cos(40°)).[/tex]
- \(t\) is the time calculated in step 1.
Plug in the values:
[tex]\[d_x = (30 \cdot \cos(40°)) \cdot 3.06 \approx 71.1 \, \text{m}\][/tex]
So, the rock was released approximately 71.1 meters horizontally from the window.

Last year, sales at Company X were 10% greater in February than in January, 15% less in March than in Feb, 20% greater in April than in March, 10% less in May than in April, and 5% greater in June than in May. In which month were sales closest to Jan?a. Febb. Marc. Aprd. Maye. June
Answer:
May
Step-by-step explanation:
Let x be the sales in January,
∵ Sales were 10% greater in February than in January,
So, the sales in February = (100 +10)% of x
= 110% of x
= [tex]\frac{110x}{100}[/tex]
= 1.1x
∵ it is 15% less in March than in Feb,
Sales in march = (100-15)% sales in February
= 85% of 1.1x
= 0.935x
∵ It is 20% greater in April than in March,
Sales in April = (100+20)% of sales in march
= 120% of 0.935x
= 1.122x,
∵ It is 10% less in May than in April
Sales in May = (100-10)% of sales in march
= 90% of 1.122x,
= 1.0098x,
∵ It is 5% greater in June than in May
Sales in June = (100+5)% of sales in march
= 105% of 1.0098x,
= 1.5147x
∵ 1.0098x is much closure to x than 1.1x, 0.935x, 1.122x and 1.5147x
Hence, the sales in May is closest to sales in January.

A lion is running 75 feet per second and is 108 feet behind a wildebeest that is running at 66 feet per second. A lion can only maintain this speed for a very short period. How many seconds will it take lion to catch up to the wildebeest?
Answer:
12 seconds
Step-by-step explanation:
75 t=66t+108
75t-66t=108
9t=108
t=108/9=12
Answer:
The answer to your question is: 12 seconds
Step-by-step explanation:
Lion v = 75 ft/s
wildebeest = 66 ft/s and is 108 feet behind the lion
t = time = ?
Formula
v = d/ t solve for d d = vt
Process
lion d = 75t
wildebeest = d = 108 + 66t
Now
75t = 108 + 66t
solve for t 75t - 66t = 108
9t = 108
t = 12 s
Two persons are to run a race, but one can run 10 meters per second, whereas the other can run 4 meters per second. If the slower runner has a 75-meter head start, how long will it be before the faster runner catches the slower runner, if they begin at the same time?
Answer:12.5 seconds
Step-by-step explanation:hconsidering Runner 1 with a speed of 10m/s
and Runner 2 with a speed of 4 m/s
the equation of displacement for a uniform movement is
x=V*t
so x1=V1*t
and x2=V2*t
and the problem condition is x2=x1+75m
so we proceed to solve the equations.
from equation 2 t=x2/V2
substituting in equation 1 we have
x1=V1(x2/V2) and then the 3 equation
x1=V1((x1+75m)/v2
finally x1=75*(V1/(V2-V1)) =75*(10/(10-4))=125m
then t=(x1/v1)=125/10=12.5 seconds
Answer:
12.5 seconds
Step-by-step explanation:
Speed of the first person = 10 meter per second
Speed of the second person = 4 meter per second
Relative velocity of faster person = 10 - 4 = 6 meter per second
since distance between both the person is = 75 meter.
Therefore, time to cover this distance by faster person = [tex]\frac{Distance}{Speed}[/tex]
[tex]\frac{75}{6}[/tex]
= 12.5 seconds.
Faster runner catches the slower runner after 12.5 seconds.

Answer:
(x, y) = (-1, -3) or (4, 12)
Step-by-step explanation:
A graphing calculator can show the solutions to this system.
__
You can equate expressions for y and solve for x.
3x = x^2 -4
x^2 -3x = 4 . . . . add 4-3x
x^2 -3x +2.25 = 6.25 . . . . complete the square by adding (-3/2)^2 where -3 is the coefficient of x.
(x -1.5)^2 = 2.5^2 . . . . . . rewrite as squares
x -1.5 = ±2.5 . . . . . . . . . . take the square root

In the continental United States the ratio of states that border an ocean to strays that don't border an ocean is 7:9. How many of the states border an ocean
What is the equation of a line that contains the point (4, 0) and is parallel to x + y = 2?
Answer:
x + y = 4 or y = -x + 4
Step-by-step explanation:
0 = -1[4] + b
4 = b
y = -x + 4
If you want it in Standard Form:
y = -x + 4
+x +x
_________
x + y = 4 >> Line in Standard Form
* Since the rate of change [slope] is -1 and that parallel lines have SIMILAR SLOPES, -1 remains the same.
