The graph is made and attached.

Given, the equation is x ₋ √x₊3 = 0

substitute values for x from the interval ₋1 to 5 and then graph the points.

for x = ₋1:

₋1 ₋ √₋1 ₊ 3 = 0

₋1 ₋ 1.42 = 0

₋2.42

for x = 0

0 ₋ √0₊3 = 0

₋1.74

for x=1

1 ₋ √1₊3 = 0

1 ₋ √4 = 0

1 ₋ 2 = 0

₋1

for x = 2

2 ₋ √2₊3 = 0

2 ₋ √5 = 0

2 ₋ 2.24 = 0

0.24

for x = 3

3 ₋ √3₊3 = 0

0.55

for x = 4

4 ₋ √4₊3 = 0

4 ₋ √7 = 0

1.25

for x = 5

5 ₋ √5₊3 = 0

2.17

hence we have the points (₋1,₋2.42) (0,₋1.74)(1,₋1)(2,0.24)(3,0.55)(4,1.25) and(5,2.17)

plot the above points on the graph.

Using a system of equations, the solution matrix that gives the weight of a fizgig and the weight of a whatsit is:

[x y] = [5 4]

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

For this problem, the variables are given as follows:

Two fizgigs and three whatsits weigh 22 noozwhats, henec:

2x + 3y = 22.

Four fizgigs and two whatsits weigh 28 noozwhats, hence:

4x + 2y = 28.

Simplifying by 2:

2x + y = 14

y = 14 - 2x.

Replacing in the first equation:

2x + 3(14 - 2x) = 22

2x + 42 - 6x = 22

4x = 20

x = 20/4

x = 5 noozwhats.

y = 14 - 2(5) = 4 noozwhats.

Hence the solution matrix that gives the weight of a fizgig and the weight of a whatsit is:

[x y] = [5 4]

Answer:

Step-by-step explanation:

The dimensions of the original piece of cardboard are 24 inches by 12 inches

The given parameters are:

Length (l)= Width (w) + 12

Length of the square cut out = 6

Volume of box, V = 1728

The volume of the box is then calculated as

V = Length of squares * Length * Width

This gives

V = 6 * (w + 12) * w

So, we have:

6 * (w + 12) * w = 1728

Divide both sides by 6

(w + 12) * w = 288

Expand

w^2 + 12w - 288 = 0

Using a graphing calculator, we have:

w = 12

Substitute w = 12 in l = w + 12

Evaluate

l = 12 + 12

l = 24

Hence, the dimensions of the original piece of cardboard are 24 inches by 12 inches

Lorene plans to make a box from rectangular sheets of cardboard from which she cuts out 6 inches squares from each corner. The length of the original piece of cardboard is 12 inches more than the width. If the box is 1728 inches cubed, determine the dimensions of the original piece of cardboard.

The solution of the given equation is y = (6x - 11)/4.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We have been given that equation as

⇒ 6x - 4y = 11

We have to determine the solution for y.

⇒ 6x - 4y = 11

Rearrange the terms of the above equation and solve for y,

⇒ 4y = 6x - 11

Divided by 4 on both the side of the equation, we get

⇒ y = (6x - 11)/4

Hence, the solution of the given equation is y = (6x - 11)/4.

Answer:

The Area model for the fig. is, = 3/5(2/5 + 1/3).

Step-by-step explanation:

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies. Consider your square as being composed of smaller unit squares.

Rectangle area = l x b

Given that, let's imagine the fig as a rectangle with a width of 2/5+1/3 and a length of 3/5.

As we know , Area of rectangle = l x b

l=3/5

b=2/5+1/3

Answer:

12.87

Step-by-step explanation:

Since we know that line CD is a perpendicular bisector, triangle ACD is a right triangle, and thus we can apply the Pythagorean theorem to determine the length of side CD. Since the Pythagorean theorem states that a^2 + b^2 = c^2, where c is the hypotenuse and a and b are the adjacent sides, we can plug in the values of side AD and AC.

As side CD is the bisector of side AB, sides AD and DB are both half the length of side AB, so:
AD = 11/2
AD = 5.5

We now know two values of our equation, and thus we can solve for the missing third value.

5.5^2 + b^2 = 14^2
14^2 - 5.5^2 = b^2
196 - 30.25 = b^2
165.75 = b^2
[tex]\sqrt{165.75} = b[/tex]
b = 12.87

The surface area of square pyramid is 64 ft²

What is square pyramid?
In terms of geometry, a square pyramid is a pyramid with a square base and four lateral faces. A pyramid is a type of polyhedron with three or more triangular faces that meet above its base (the apex). A square pyramid is a pentahedron, a three-dimensional shape with a total of five faces. The Great Pyramid of Giza is a well-known example of a real-life pyramid. When we learn about pyramids, we must also learn other concepts that are related to them, such as the volume and area of the pyramid. In this article, we will learn what a square pyramid is, its types, characteristics, surface area formulas, and volume formulas with numerous examples and solutions.

For a square pyramid, the surface area is given by the following equation:

SA = a^2 + 4(a)(h)
where a is the side length of the base and h is the slant height.
In this case, a = 4 and h = 3. Therefore,
SA = 4^2 + 4(4)(3)
SA = 16 + 48
SA = 64 ft^2

The equation that represent the same salary is 55,000x+2,500x=64,000+1500x

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.

Given:

Katherine has a new job and earns salary of $55,000.  Katherine will receive a salary increase of $2,500 per year .

max has a new job and earns a salary of $64,000. Max will receive a salary increase of $1,500 per year.

So, in the case they would have the same salary for some x years the expression can be

Katherine salary along with increment= 55000+ 2500x

Max salary along with increment= 64000+ 1500x

Hence, equation ca be used to find x, the number of years it will take Katherine to earn the same salary as Max is 55,000x+2,500x=64,000+1500x.

The expression is  negative one eighteenth times x plus 18.

The expression says "one sixth times the quantity 4 times x plus 18 end quantity minus 13 over 18 times x".

Therefore, the statement can be expressed as follows;

1 / 6 × 4 × x + 18 - 13 / 18 × x

Therefore, let's simplify it

1 / 6 × 4 × x + 18 - 13 / 18 × x

4x / 6 + 18 - 13 / 18 × x

4x / 6 + 18 - 13 / 18 x

Step-by-step explanation: :)

The product of matrices A and B​ is  the elements 0 and 6 in the first row and -10 and -8 in the second row.

Given that the matrix A = 2 - 143 and B = -11-2-4.

Assume that the order of the matrix of A and B is 2x2.

The elements of matrix A are as below:a₁₁ = 2, a₁₂ = -1, a₂₁ = 4, a₂₂ = 3

The elements of matrix B are as below:b₁₁ = -1, b₁₂ = 1, b₂₁ = -2, b₂₂ = -4

We need to find the product of matrices A and B.

Let C denote the product of matrices A and B.

Then the order of the matrix C is 2x2 and its elements are calculated as follows : c₁₁ = a₁₁·b₁₁ + a₁₂·b₂₁ ⇒ c₁₁ = 2(-1) + (-1)(-2)⇒ c₁₁ = -2 + 2⇒ c₁₁ = 0 c₁₂ = a₁₁·b₁₂ + a₁₂·b₂₂⇒ c₁₂ = 2.1 + (-1)(-4)⇒ c₁₂ = 2 + 4⇒ c₁₂ = 6c₂₁ = a₂₁b₁₁ + a₂₂b₂₁⇒ c₂₁ = 4(-1) + 3(-2)⇒ c₂₁ = -4 -6⇒ c₂₁ = -10c₂₂ = a₂₁b₁₂ + a₂₂b₂₂⇒ c₂₂ = 4(1) + 3(-4)⇒ c₂₂ = 4 - 12⇒ c₂₂ = -8

Therefore the required matrix has the elements 0 and 6 in the first row and -10 and -8 in the second row.

For Mary:

Principal = $ 30,000

Interest rate = 4 %

Compounded annually

t = 3 years

Amount = $ 30,000 ( 1 + 4 / 100 )³

A = 30,000 ( 1.04)³

A = 30,000 ( 1.124864 )
