Answer:

(4.449, 0.449) and (-0.449, -4.449)

Step-by-step explanation:

xy = 2

y = [tex]\frac{2}{x}[/tex]

Vertical asymptote → x = 0

Horizontal asymptote → y = 0

Input-output values for the equation,

x          -2         -1            1           2           4

y          -1         -2            2          1          0.5

Input-output values of the equation,

x - y = 4

x         -2          -1            0            1            2

y         -6          -5          -4           -3          -2

Solutions of the system of equations → (4.449, 0.449) and (-0.449, -4.449)

Answers

Answer:

x=12

Step-by-step explanation:

We know that a right angle is 90 degrees. So we can make the equation [tex]35+4x+7=90.[/tex] Now, we can solve fore X! We can combine 35 and 7 to make the equation [tex]4x+42=90[/tex]. In order to isolate x we have to subtract 42 from both sides, getting us the equation [tex]4x=48.[/tex] Now, in order to isolate x we must divide each side by 4, getting us the equation [tex]12=x[/tex].  To prove that x=12, we can subsitute x for 12.  This means that we can do [tex]35+4(12)+7=90. Or, 35+48+7 =90,[/tex] which simplified, is 90=90, making x=12 true. Hope this helps :)

Ms. Rhodes purchased 8 pounds of potatoes for $18.08. At this rate, what is the cost per pound of potatoes? Use a proportion to solve. include how you did this work <3

Answers

Answer:

$2.20

Step-by-step explanation:

If you do long division you get 2 dollars as total with a decimal of 20 do that's your answer.

Answer:

The cost per pound of potatoes is $2.26.

Step-by-step explanation:

You have to divide the total cost by the total pounds.

So in this case, the total cost is $18.08.

There is a total number of 8 pounds.

So you do:

$18.08 / 8 pounds

             =

$2.26/lb of potatoes

Given:

The expressions are

(c) [tex]\left\{\left(\dfrac{2^4\times 3^6}{12^2}\right)^0\right\}^3[/tex]

(d) [tex]\dfrac{13^3\times 7^0}{\{(65\times 49)^2\}^1}[/tex]

To find:

The simplified form of the given expression.

Solution:

(c)

We have,

[tex]\left\{\left(\dfrac{2^4\times 3^6}{12^2}\right)^0\right\}^3[/tex]

We know that, zero to the power of a non-zero number is always 1. So, [tex]\left(\dfrac{2^4\times 3^6}{12^2}\right)^0=1[/tex]

[tex]\left\{\left(\dfrac{2^4\times 3^6}{12^2}\right)^0\right\}^3=(1)^3[/tex]

[tex]\left\{\left(\dfrac{2^4\times 3^6}{12^2}\right)^0\right\}^3=1[/tex]

Therefore, the value of the given expression is 1.

(d)

We have,

[tex]\dfrac{13^3\times 7^0}{\{(65\times 49)^2\}^1}[/tex]

It can be written as

[tex]\dfrac{13^3\times 7^0}{\{(65\times 49)^2\}^1}=\dfrac{13^3\times 1}{(65\times 49)^2}[/tex]

[tex]\dfrac{13^3\times 7^0}{\{(65\times 49)^2\}^1}=\dfrac{13\times 13\times 13}{(65\times 49)(65\times 49)}[/tex]

[tex]\dfrac{13^3\times 7^0}{\{(65\times 49)^2\}^1}=\dfrac{13}{(5\times 49)(5\times 49)}[/tex]

[tex]\dfrac{13^3\times 7^0}{\{(65\times 49)^2\}^1}=\dfrac{13}{60025}[/tex]

[tex]\dfrac{13^3\times 7^0}{\{(65\times 49)^2\}^1}=\dfrac{13}{60025}[/tex]

Therefore, the value of given expression is [tex]\dfrac{13}{60025}[/tex].

Answers

B .......................................

120l NaBr solute is saturated at 70 degrees. In this case option b is correct when  saturated at 70 degrees.

NaBr is the chemical formula for sodium bromide. It is an inorganic compound composed of sodium (Na) and bromine (Br). Sodium bromide is a white, crystalline solid that is highly soluble in water.

In terms of its properties and uses, sodium bromide has various applications. It is commonly used in the pharmaceutical industry as a sedative and anticonvulsant drug. Sodium bromide is also used in the oil and gas industry as a completion fluid in well drilling and workover operations. Additionally, it finds applications in photography as a component of some film developers.

As a salt, sodium bromide dissociates into sodium ions (Na+) and bromide ions (Br-) when dissolved in water. These ions can participate in various chemical reactions and have different effects depending on the specific application or purpose.

WXY=ZYX. Find p.​

Answers

Answer:

I believe this is a "trick" question. From the equations given, I can get 3 different solutions.

Step-by-step explanation:

WY = XZ because corresponding parts of congruent triangles are congruent.

(7p + 13) + 2p = 18 + 4

9p + 13 = 22

9p = 9

p = 1

∠ZXY = ∠WYX because corresponding angles of congruent triangles are congruent.

Because ∠ZXY = ∠WYX, ΔVXY is isosceles and XV = YV

2p = 4 because corresponding parts of congruent triangles are congruent.

p = 2

also, because of congruency,

WV = ZV

7p + 13 = 18

7p = 5

p = 5/7

The triangle ΔWXY and ΔZYX are congruent triangles to each other. Then the value of the variable 'p' will be 1.

What is the triangle?

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

The triangle ΔWXY and ΔZYX are congruent triangles to each other. Then the ratio of the corresponding sides will be one. Then the equation is given as,

WX / XZ = 1

XW = XZ

WV + VY = XV + VZ

7p + 13 + 2p = 18 + 4

9p = 9

p = 1

The triangle ΔWXY and ΔZYX are compatible triangles with one another. Then the worth of the variable 'p' will be 1.

Find the value of x.

Answers

Answer and Step-by-step explanation:

We see that this is a right angle, which means the entire angle is equal to 90.

We can find what x is by adding this expression and 44 and equaling it to 90.

90 = x + 9 + 44

90 = x + 53

37 = x

The value of x is 37.

It’s a right angle so it equals 90 degrees. 90- 44= 46 and 46-9= 37

quadrilateral vwxy with vertices v(-2,-1) w(-5,-2) x(-8,-7) and y(1,-6): 18o from the origin

Answers

Given:

The vertices of a quadrilateral are v(-2,-1) w(-5,-2) x(-8,-7) and y(1,-6).

To find:

The vertices of the image of quadrilateral vwxy after 180° about the origin.

Solution:

If a figure rotated 180° about the origin, then the rule of rotation is

[tex](x,y)\to (-x,-y)[/tex]

Using this rule, we get

[tex]v(-2,-1)\to v'(2,1)[/tex]

[tex]w(-5,-2)\to w'(5,2)[/tex]

[tex]x(-8,-7)\to x'(8,7)[/tex]

[tex]y(1,-6)\to y'(-1,6)[/tex]

Therefore, the vertices of image of quadrilateral vwxy after 180° about the origin are  v'(2,1), w'(5,2), x'(8,7), y'(-1,6).

Answers

In order to find this, you have to find both the top and the bottom volumes and add them together. To find the bottom volume you’d use the formula lwh or Length*width*height. First you’d substitute in the numbers for the formula and get 9yd*8yd*4yd and get 288yd cubed. Then to find the top one you use the same formula and use 4yd*3yd*2yd and get 24yd cubed. Finally you add the two volumes together and get 288yd cubed + 24yd cubed=312yd cubed
