Answer:

Since r is the distance from the origin to (x,y), it is the magnitude r=√x2+y2. Alternatively, from the equation (1), one can calculate directly that x2+y2=r2cos2θ+r2sin2θ=r2(cos2θ+sin2θ)=r2.

Answer:

8^4

Step-by-step explanation:

A 'base' is a number with an exponent.

The expression [tex]8^4[/tex] has the base 8.

We need to find which of the given term has an expression with a base of 8.

A numerical system's number basis, or base for short, informs us of the particular or distinctive symbols and notations it employs to express a value. The number used to construct a power with an exponent, such as the 3 in 3², is known as the base.

In the expression [tex]8^4[/tex], 8 is the base and 4 is the power or exponent.

Therefore, the expression [tex]8^4[/tex] has the base 8.

The domain is all of the x-values of a function.

So, we take all of the x-values from our points.

0,-1,2,1

To express the domain, you order the numbers from least to greatest and put it in brackets, so the domain is {-1,0,1,2}.

Have a wonderful day! :D

Answer:{-1,0,1,2}

Step-by-step explanation:

Step-by-step explanation:

this relation is not a function cuz each x pair (domian) has only one image in y pair (codomain) so we will have all the ×-axis pairs meeting with y-axis in only one point as they have one image as this is the rule of having a function so what in front of us the positive part of x-axis has two images in y-axis

u can knew it by another way draw a vertical line and if it meets in two point or more than one then the relation is not a function s o if we draw a vertical line in the right part of the graph it will meats in two points then not a function

the domain is all the pairs of this relation taken in x-axis which are [0,infinity[ and range is the y-axis images if the fomain in x-axis which are ]-infinity, infinity[

Answer:

y = -2x - 8

Step-by-step explanation:

Parallel lines always have the same slope. Here, it is -2.

So, our equation so far looks like this:

y = -2x + b, where b is the y-intercept

We need to find b. We know our line passes through (-4, 0), so let's plug -4 in for x and 0 in for y:

y = -2x + b

0 = -2 * (-4) + b

0 = 8 + b

b = -8

Since b = -8, our equation is thus y = -2x - 8.

Answer:

I think its 7x7 because it equals to 49 and its the closest to 50 and the rug would fit better than 6x 8 1/2=51 becuase 49 is smaller and would fit better.

Step-by-step explanation:

The area of a 2D form is the amount of space within its perimeter. The correct option is B, 8ft diameter.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

Since Courtney and Malik want the rug to fit in an area of 50-square-foot space. Therefore, we need to first calculate the area of the given rugs, and then choose the one that can completely cover the area.

Now, as it can be seen that the only rug that can completely cover the 50-square-foot area is the one that has a diameter of 8 ft.

Hence, the correct option is B, 8ft diameter.

Answer:

The width of the rectangle is 3.4 inches

Step-by-step explanation:

3.6 inches = length  LxW=Area

W= width

Perimeter= 2x(Length)+2x(Width) 2x3.6=7.2

7.2+2(W)=14.00 subtract 7.2 on both sides 14.00-7.2=6.8

2(Width)=6.8 divide both sides by 2 6.8/2=3.4

So width of rectangle is 3.4

Step-by-step explanation:

We have ST=5x, TU=3x+32 and they're equal if T is the midpoint:

ST = 5x = 80

So TU = 80

Answer:

[tex]x=2y+3[/tex]

Step-by-step explanation:

So we have the equation:

[tex]x-2y=3[/tex]

And we want to solve for x. In other words, we want to isolate the x-variable.

So, add 2y to both sides of the equation.

[tex](x-2y)+2y=(3)+2y[/tex]

On the left, the 2y cancel. Simplify the right:

[tex]x=2y+3[/tex]

And we're done!

Answer:

x = 3 + 2y

Step-by-step explanation:

This is the answer because:

1) First, you have to isolate x, in order to isolate x you have to bring x to the end of the equation.

2) Then, you have to add 2y to both sides of the equation.  

Another way you can think of this is:

1) If you add 3 + 2y you would figure out the answer because if you want to find x for a subtraction equation, you can add the answer to the equation with the number.

For example, x - 20 = 10, now to figure this equation out, you can either isolate the x, or you can add the answer in the equation with the remaining number in the equation.

Answer:

angle XYZ = 40°

Step-by-step explanation:

given,

angle XYZ = 2x°

angle PQR = (8x-20)°

now,

2x+8x-20° = 180°{being supplementary angle}

or, 10x - 20° = 180°

or, 10x = 180°+20°

or, x = 200°/10

or, x = 20°

again,

angle XYZ = 2x°

= 2× 20°

= 40°
