The dimension of the rectangle 18 feet by 13feet

A rectangle is a 2 dimensional shape having two sides.

Area of a rectangle = length * width

Given the following parameters

Length = x + 8

Width = x + 3

Area = 234ft^2

Substitute the given parameters into the formula

(x+8)(x+3) = 234
x² + 3x + 8x + 24 = 234

x² + 11x = 234 - 24
x² + 11x = 210

x² + 11x - 210 = 0

Factorize

x² + 21x - 10x - 210 = 0

x(x+21) - 10(x+21) = 0
x - 10 = 0
X = 10

Leength = x + 8

Length = 18 feet

Width = x + 3

Width = 3 + 10
Width = 13feet

Hence the dimension of the rectangle 18 feet by 13feet

Answer:

d = 4/c.

Step-by-step explanation:

Inverse variation is :  d = k/c where k is a constant.

Here k = 4.

The equation of the line in point-slope form is: y - 12 = -4/5(x - 5).

It is given as, y - b = m(x - a), where (a, b) is a point on the line and m is the slope of the line.

Rewrite 5x-4y=10 in slope-intercept form:

-4y= - 5x + 10

y= -5x/-4 + (10/-4)

y = 5/4x - 5/2

The slope is 5/4

The line that is perpendicular to 5x-4y=10 will have a slope which is the negative reciprocal of 5/4, which is -4/5.

Substitute (5, 12) and -4/5 into y - b = m(x - a):

y - 12 = -4/5(x - 5) [point-slope form]

Answer:

max = 150

Step-by-step explanation:

the maximum height is the value of the y- coordinate of the vertex.

given a quadratic equation in standard form : y = ax² + bx + c = 0 ( a ≠ 0 )

then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

- 16x² + 64x + 86 = 0 ← is in standard form

with a = - 16 and b = 64 , then

[tex]x_{vertex}[/tex] = - [tex]\frac{64}{-32}[/tex] = 2

substitute x = 2 into the quadratic for corresponding y- coordinate

- 16(2)² + 64(2) + 86 = - 16(4) + 128 + 86 = - 64 + 128 + 86 = 150

vertex = (2, 150 )

then maximum height is 150 units

[tex]a_n=33+6n[/tex]

Step-by-step explanation:

General form of arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]

Given terms:

To find the common difference, subtract a term from the next:

[tex]d=a_3-a_2=51-45=6[/tex]

Substitute [tex]a=39[/tex] and [tex]d=6[/tex] into the formula:

[tex]\implies a_n=39+6n-6[/tex]

[tex]\implies a_n=33+6n[/tex]

Answer:

f⁻¹(x) =

Step-by-step explanation:

Given function,

→ f(x) = 5x - 6

We are supposed to find ths inverse of the given function. Consider the function, y = f(x).

→ y = 5x - 6

Add 6 to both sides.

→ y + 6 = 5x - 6 + 6

Solve the equation.

→ y + 6 = 5x

Division both sides by 5.

→ y + 6/5 = 5x/5

Solve the equation.

→ (y + 6)/5 = x

Can be re-written as,

→ x = (y + 6)/5

Now, recall f(x) = y, this implies x = f⁻¹(y).

→ f⁻¹(y) = (y + 6)/5

So the final answer is:

→ f⁻¹(x) = (x + 6)/5

Equally likely refers to two or more possible outcomes of a given situation that have the same probability or the same likelihood to occur. For example, if you throw a die, there are six possible outcomes. You could get 1, 2, 3, 4, 5, or 6. These outcomes are equally likely to occur.

The total surface area of the three figures are 702 square feet.

According to this problem, we are required to determine the amount of metal needed to build three pieces with the dimensions presented in the figure.

In this case, we need to estimate the total surface area ([tex]A_{T}[/tex]), in square feet, required for the production of the three pieces, that is, the product of the number of pieces (n), no unit, and the surface area of each piece (A).

Now we proceed to calculate the total surface area:

[tex]A_{T} = n\cdot A[/tex]

[tex]A_{T} = 3\cdot \left[(5\,ft)\cdot (8\,ft) + (2\,ft)\cdot (8\,ft)+(8\,ft)\cdot (7\,ft)+(3\,ft)\cdot (8\,ft) \\[/tex]

[tex]+(5\,ft)\cdot (8\,ft)+2\cdot (3\,ft)\cdot (5\,ft) + 2\cdot (4\,ft)\cdot (2\,ft) + (3\,ft)\cdot (4\,ft) ][/tex]

[tex]A_{T} = 702\,ft^{2}[/tex]

The system of equations that represents the situation is given by:

C. x² – 2y ≥ 5000, 2x + 5y < 1000

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

In tis problem, the company's stock is represented by the expression x² - 2y, and the goal is a stock value of at least $5,000, hence the first equation is given by:

x² – 2y ≥ 5000

Answer:

answer can be any numbers but I will choose

x = 50° and y =130°

Step-by-step explanation:

We know all the inner degree of rhombus =360°

Then, x+y+x+y = 360°

or,2x + 2y = 360°

or, 2(x + y) = 360°

or, x + y = 360°/2

or,x + y = 180°

Let x = 50° then

50° + y = 180°

or, y = 180° - 50°

or, y = 130°

Answer:

x = 13

Step-by-step explanation:

Vertical angles are always congruent (equal)

⇒ ∠A =∠B

⇒ (8x - 12) = (6x + 14)
