What is the perimeter of the triangle?

The coordinates of the image A'B'C are A(-2, 6) B(-3, 4) C(-8, 2)

Given data :

Triangle ABC has vertices A(6,2), B(3,4), and C (2,8).

Although I am aware that the coordinates must rotate around the origin, I am unsure of the signs (+ or -).

Consequently, the shape is in the second quadrant of the graph, and the 90-degree angle should be in the fourth quadrant rather than the first (which is 180 degrees anticlockwise) or third (.180 anticlockwise)

a) Equation for length and width of the rectangular rug be [tex]x^{2}[/tex] + 8x - 42 = 0

b) Width of the rectangular rug be 3.5 feet

c) Diagonal of the rectangle is 12.5 feet

What is the area of the rectangle?

The area of ​​a rectangle is the area occupied by the rectangle within its four sides or boundaries.

The area of ​​a rectangle depends on its sides. Basically, the formula for area is equal to the product of the length and width of a rectangle. The perimeter of a rectangle is equal to the sum of all its four sides

It is given that area of a rectangular rug id 42 square feet. The rug is 8 feet longer than its wide

a) Let the width of the rectangular rug be x feet

Length of the rectangular rug = (x+8) feet

area of rectangular rug = Length × width = x × (x + 8) = [tex]x^{2}[/tex] + 8x

area of rectangular rug = 42

[tex]x^{2}[/tex] + 8x = 42

[tex]x^{2}[/tex] + 8x - 42 = 0

Therefore, equation for length and width of the rectangular rug be [tex]x^{2}[/tex] + 8x - 42 = 0

b) If the length of the rectangle is 12 feet

Area of rectangle = 42 square feet

length × width = 42 square feet

12 × width = 42 square feet

width = 42/12 = 3.5

Therefore, width of the rectangular rug be 3.5 feet

c) Length of the diagonal of the rectangle = [tex]\sqrt{length^2+width^2}[/tex]

= [tex]\sqrt{12^2+3.5^2}=\sqrt{144+12.25}=\sqrt{156.25}= 12.5[/tex]

Therefore, diagonal of the rectangle is 12.5 feet

Answer: y = 3/4x

Step-by-step explanation:

(100, 75)

(200, 150)

find slope

150 - 75 / 200 - 100

75 / 100 = 3/4

plug values into formula y=mx+b to find y-intercept

y = 3/4x + b

75 = 3/4(100) + b

75 = 75 + b

b = 0

Even though A and B are both square, AB always equals BA.

Could someone please assist me in demonstrating that b=c follows from ab=ac and a does not equal 0. You can only apply the field axioms. Here is my try.

ab=ac then, ab-ac=0

a(b-c)=0

a(0)=0 Since a cannot equal zero (this has already been shown), (b-c) must also equal zero, leaving us with...

b-c=0

b=c

The only issue I have with the above is that I presupposed that a did not equal 0. I'm not sure if this is okay because the original theorem I'm attempting to prove includes the claim that "a does not equal 0."

think about this conceptually first. The difference between their rates of work is going to be the total speed at which the chalk board fills up (speed of writing - speed of erasing).

Ok, so we need to find the speed that Bart is writing, and the speed at which Nelson is erasing.

Bart: 50 minutes/ 1 board

However, we want to find his speed, which will be in boards/minute. Flip the fraction to get 1 board/50 minutes. Then multiply top and bottom by 1/50 in order to get 1/50 board per minute.

Bart's Speed = 1/50 board per minute

Do the same for Nelson, to get 1/80 board per minute (erasing).

The difference between these will be 1/50 - 1/80 = 3/400 board per minute

Since we want to know how long it will take to fill the board at this rate, we multiply 1 board * 1/(3/400) minute per board - this is the same as 1 * 400/3

So, the answer is 400/3 minutes, or 133.33 minutes, or 2 hours, 13 minutes.

#2

This is the same idea as #1. His speed without the headwind is 2000 miles/5 hours = 400miles/hour.

His speed with the headwind is 2000 miles/8 hours = 250 miles/hour.

400m/h - 250m/h = 150m/h

The speed of the wind is 150 miles/hour.

What is a System of Equations?

A system of equations in algebra is made up of two or more equations that are solved together. "A group of equations satisfied by the same set of variables are called a system of linear equations. Finding the values of the variables employed in the system of equations is the first step towards solving it. While maintaining the balance of the equations on both sides, we compute the values of the unknown variables. Finding a variable whose value makes the condition of all the given equations true is the primary goal of solving an equation system.

The factored form of f(x) is f(x) =  (x+2) (x+2)(x+4)      

What is a factor?

A factor is a number/expression that divides another number/expression, leaves zero remainder . In other words, if multiplying two numbers/expressions gives us a product, then the numbers/expressions we are multiplying are factors of the product because they are divisible by the product.

f(x) = x³ +8x² + 20x + 16

The value of x at which f(x) is zero, is the root

x= -2 is a root

so, ( x- (-2) ) = ( x+2) is a factor

Divide the polynomial  x³ +8x² + 20x + 16  by  ( x+2)  using long division method:

x+2)  x³ +8x² + 20x + 16  ( x² + 6x + 8

        x³ + 2x²

f(x)= (x+2) (x² + 6x + 8 )

Factors of (x² + 6x + 8 ) are (x+2)(x+4)      

f(x) =  (x+2) (x+2)(x+4)

Answer:

y=x-4

Step-by-step explanation:

if the slope is 1, the y intercept is -4

What is the equation of the line that passes through the point (-1,-5) and has a slope of 1?

The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.

Since the line passes through the point (-1,-5) and has a slope of 1, we can substitute these values into the equation to solve for the y-intercept. We get:

y = 1x + b

(-5) = 1(-1) + b

-5 = -1 + b

-4 = b

Therefore, the equation of the line that passes through the point (-1,-5) and has a slope of 1 is y = 1x - 4.

Answer:

2 x x = 2x

2 x 4 = 4

so 2x + 8 is the answer.

To solve this equation we must expand its terms so that we can then multiply and add.

Equations are those mathematical equalities divided between two expressions which are called members and separated by their equal sign, in which known elements and unknown or unknown data appear, related by mathematical operations.

So, our result of the equation is 2x + 8

[tex]\frac{3x-3}{5}=\frac{24+3x}{20}[/tex]          Original equation. A proportion can be set up so that

                              combine forming 24, which continues to be added to 3x.

                              15 and 5 can be combined to become 20.

20(3x-3)=5(24+3x) Now, cross multiply. This involves the distribution of one

                               term to the terms it's multiplied by. 20*3x=60x and

                               20*-3=-60. 5*24=120 and 5*3x=15x.

60x-60=120+15x     Now, the goal is to get x alone on one side. You can do

                                this by combining like terms. Subtract 15x from both

The surface area of this cylinder is 118.378 square yards. 3.6 yard is the height.

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

For instance, the surface area of a cube is its surface area if we need to determine how much paint is needed to paint it. Square units are used to measure it at all times.

The terms "lateral surface area," "curved surface area," and "total surface area" refer to three different forms of surface area.

Surface area and volume are the cylinder's two main characteristics because it is a three-dimensional form. The area of the two circular bases combined with the cylinder's curved surface area equals the cylinder's overall surface area. Its volume is the three-dimensional area that a cylinder takes up.

Given that,

Surface area (A) of the cylinder = 118.378 square yards.

radius (r) = 2.9 yard

As we know, A = 2πrh + 2πr²

putting the values we get -

or, 118.378 = 2πr (h + r)

or, 118.378 = 2 × 3.14 ×2.9 × (h + 2.9)

or, 118.378 = 18.212 × (h + 2.9)

or, 6.5 = h + 2.9

or, h = 6.5 - 2.9

or, h = 3.6 yard

Thus, 3.6 yard is the height of the cylinder.
