Kitty [74]

Answer:

160 ft²

Step-by-step explanation:

The width is 40% of the length, so is ...

0.40 × 20 ft = 8 ft

The area is the product of length and width:

A = LW

A = (20 ft)(8 ft) = 160 ft²

13x=6 what is x in number form please and thank you

Neporo4naja [7]

$\huge\text{Hey there!}$

$\mathsf{13x = 6}$

$\huge\textsf{DIVIDE 13 to BOTH SIDES}$

$\mathsf{\dfrac{13x}{13}=\dfrac{6}{13}}$

$\rm{CANCEL \ out: \dfrac{13}{13} \ because \ that \ gives \ you \ 1}$

$\rm{KEEP: \dfrac{6}{13} \ because \ that \ gives \ you \ the \ value \ of \ x}$

$\boxed{\boxed{\mathsf {Answer: x = \bf \dfrac{6}{13}}}}\huge\checkmark$

$\boxed{\textsf{or you could say \boxed{\mathsf{x = \underline{\bf 0.461538}}} they both equal to the same thing}}\huge\checkmark$

$\large\text{Good luck on your assignment and enjoy your day!}$

A rectangular exercise mat has a perimeter of 36 feet . The length mat is twice the width. Write and solve an equation to determ

Goshia [24]

ANSWER

72 square feet

EXPLANATION

The perimeter of a rectangle is given by:

P= 2l+2w

It was given that, the perimeter of the rectangular mat, is 36 feet.

36= 2l+2w

Divide through by 2.

$18 = l + w...(1)$

It was given also that, the length of the mat is twice its width.

This implies that,

$l = 2w ...(2)$

Put equation (2) into equation (1) to get,

$18 = 2w + w$

$18 = 3w$

$w = 6 \: ft$

This means that the length is 12 ft.

The area of the rectangular mat is

$A = l \times w$

$A = 6 \times 12 = 72 {ft}^{2}$

Write functions for each of the following transformations using function notation. Choose a different letter to represent each f

joja [24]

Answer:

1. Translation: g(x) = f(x-a)+b.

2. Reflection around y-axis: h(x) = f(-x)

3. Reflection around x-axis: k(x) = -f(x)

4. Rotation of 90° : $R_{90} (x,y)=(-y,x)$

5. Rotation of 180° : $R_{180} (x,y)=(-x,-y)$ .

6. Rotation of 270° : $R_{180} (x,y)=(y,-x)$ .

Step-by-step explanation:

Let us assume that the transformations namely translation, reflection are applied to a function f(x) and the rotation is applied to the point ( x,y ).

So, according to the options:

We know that 'translation moves the image in horizontal and vertical direction'.

1. As we have to translate the function f(x) 'a' units to the right and 'b' units up. So, the new form of the function becomes g(x) = f(x-a)+b.

Further, we know that 'reflection means to flip the image around a line'.

2. As, we have to reflect the function f(x) around y-axis. The new form of the function is h(x) = f(-x).

3. As, we have to reflect the function f(x) around x-axis. The new form of the function is k(x) = -f(x).

Since, 'rotation turns the image around a point to a certain degree'.

4. As, we have to rotate ( x,y ) counter-clockwise to 90° about the origin, the new form of the function is $R_{90} (x,y)=(-y,x)$ .

5. As, we have to rotate ( x,y ) counter-clockwise to 180° about the origin, the new form of the function is $R_{180} (x,y)=(-x,-y)$ .

6. As, we have to rotate ( x,y ) counter-clockwise to 270° about the origin, the new form of the function is $R_{180} (x,y)=(y,-x)$ .
