Help me plsss Wat does it means

Answer:

A

Step-by-step explanation:

12 / tan 42 = 13.32......

12 / sin 27 = 26.43....

26.43² - 12² = 552.24....

square root of 552.24... = 23.5

23.5 - 13.3 = 10.2

Answer:

(-2,4), (0,4), (-4,-2) and (2,-2)

Step-by-step explanation:

Given

[tex]A = (-5,9)[/tex]

[tex]B = (-2,9)[/tex]

[tex]C = (-8,0)[/tex]

[tex]D = (1,0)[/tex]

[tex]Translation: 2\ units\ right\ \& \ 3\ units\ down[/tex]

[tex]Dilation: \frac{2}{3}[/tex]

Required

Determine the vertices of the image RSTU

When a coordinate (x,y) is translates b units right, the new coordinate is: (x + b, y)

So, translation 2 units right gives:

[tex]A = (-5,9)[/tex] ---> [tex]A' = (-5 + 2,9) = (-3,9)[/tex]

[tex]B = (-2,9)[/tex] ---> [tex]B' = (-2 + 2,9) = (0,9)[/tex]

[tex]C = (-8,0)[/tex] ---> [tex]C' = (-8 + 2,0) = (-6,0)[/tex]

[tex]D = (1,0)[/tex] --- > [tex]D' = (1 + 2,0) = (3,0)[/tex]

When a coordinate (x,y) is translates b units down, the new coordinate is: (x, y-b)

So, translation 3 units down gives:

[tex]A' = (-3,9)[/tex] ---> [tex]A" =(-3,9-3) =(-3,6)[/tex]

[tex]B' = (0,9)[/tex] --> [tex]B" =(0,9-3) =(0,6)[/tex]

[tex]C' = (-6,0)[/tex] --> [tex]C" =(-6,0-3) = (-6,-3)[/tex]

[tex]D' = (3,0)[/tex]--> [tex]D"=(3,0-3) = (3,-3)[/tex]

Lastly, dilation of 2/3 gives:

[tex]New = Old * \frac{2}{3}[/tex]

[tex]R = (-3,6) * \frac{2}{3} = (-2,4)[/tex]

[tex]S = (0,6) * \frac{2}{3} = (0,4)[/tex]

[tex]T = (-6,-3) * \frac{2}{3} = (-4,-2)[/tex]

[tex]U = (3,-3) * \frac{2}{3} = (2,-2)[/tex]

Hence, the coordinates of RSTU are: (-2,4), (0,4), (-4,-2) and (2,-2)

Answer:

Step-by-step explanation:

y = a(x-4)^2 + 4

Plug in (2,-8) and solve for a:

-8 = a(2-4)^2 + 4

a = -3

y = -3(x-4)^2 + 4

Answer: See explanation

Step-by-step explanation:

Let the wind chimes of the same number that would make her form 100 sea shells be represented by x.

From the information given in the question, this can be denoted as:

12x + 8x = 100

20x = 100

x = 100/20

x = 5

She'll need 5 wind chimes. Let's check

12x + 8x

12(5) + 8(5)

60 + 40 = 100

Answer:

A function will not have any repeating x values...it can have repeating y values, just not the x ones. So all ur x's have to be different.

This relation is NOT a function because u have repeating x values...u have 2 x values that are 0.3

Answer:

14

Step-by-step explanation:

divide by 10

Answer:

14

Step-by-step explanation:

You have the proportion:

3 cm: 30 millimeters

divide both sides by 3

1 cm: 10 millimeters

Then, multiply both sides by 14

14cm: 140 millimeters

So 14 centimeters are in 140 millimeters

Answer:

[tex]\frac{13}{\sqrt{2}}[/tex] or 9.19 (approximately). I am confused how the question is asking for it to be typed, so it might be this: [tex]\frac{13}{\sqrt{2}}[/tex] , but if you cannot type that in, then maybe it is sin(45) * 13.

Step-by-step explanation:

The three main trigonometric ratios are: sine (o/a), cosine (a/h), or tangent (o/a) depending on the given. To help you remember them, you can use the saying SOH CAH TOA, which is sin = opposite/hypotenuse, cosine = adjacent/hypotenuse, and tangent = opposite/adjacent.

     In this problem, we are going to use one that has the hypotenuse, which rules out tangent, and leaves us with sine or cosine. Since, we are given the hypotenuse and the opposite side (from angle 45), we will be using sine. Then we just need to set up the trigonometric ratio:

sin (45) = x/13  

Then, you need to get x by itself, so you multiply 13 on each side, which leaves you with:  

x = sin(45) * 13 = 9.19 (approximately)

This could also be seen as a special right triangle, where the hypotenuse is [tex]x\sqrt{2}[/tex], and the two sides are x.

So, to find the value of x, you could also do this: 13/[tex]\sqrt{2}[/tex], which might be how the question wants it formatted.

Good luck!

Answer:

122

Step-by-step explanation:

The total surface area is 122. This is because 7 times 4 equals 28. Then you do 7 times 5 twice, which makes 35 times 2, which makes 70. This is because there are 2 triangles with 7 as the base and 5 as the height. Next, you do 4 times 3 twice, which equals 12 + 12 which adds up to 24. Now add the numbers up. 70 + 28 + 24, which = 122.

The expression for the given rectangle with width x and area y is[tex]y = -x^{2} +32[/tex]

it is given that

area of the rectangle = y

width of the rectangle = x

so the length of the rectangle will be = area/width = [tex]\frac{y}{x}[/tex]

perimeter = 64

Perimeter is the sum of all four sides of the rectangle.

we can say that,

2(length + breadth) = 64

[tex]2( \frac{y}{x} + x)=64\\\\[/tex]

[tex]\frac{y}{x} + x= 32[/tex]

[tex]\frac{y + x^{2} }{x} = 32[/tex]

[tex]y+x^{2} = 32x[/tex]

[tex]y = -x^{2} +32[/tex]

therefore, the expression for the area of the rectangle,

[tex]y = -x^{2} +32[/tex]
