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

You can use option (D) to find the area of rectangle

(D) y = - x²+32x

Step-by-step explanation:

If you can substitute your values you can find your answer

THANK YOU....

PLZZ GIVE ME A BRAINLIEST TAG

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]

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:

[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:

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
