Find the sides using distance formula:

Find perimeter:

Answer:

54.56 units (2 d.p.)

Step-by-step explanation:

The perimeter of a two-dimensional shape is the sum of the lengths of its sides.

From inspection of the given diagram, the vertices of the triangle are:

To find the lengths of each side, use the distance between two points formula.

Distance between two points

\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

\(\textsf{where }(x_1,y_1) \textsf{ and }(x_2,y_2)\:\textsf{are the two points}\)

Therefore:

\(\implies JK = \sqrt{(x_K-x_J)^2+(y_K-y_J)^2}\)

\(\implies JK = \sqrt{(-12-3)^2+(2-(-10))^2}\)

\(\implies JK = \sqrt{369}\)

\(\implies KL = \sqrt{(x_L-x_K)^2+(y_L-y_K)^2}\)

\(\implies KL = \sqrt{(-7-(-12))^2+(12-2)^2}\)

\(\implies KL=\sqrt{125}\)

\(\implies LJ = \sqrt{(x_J-x_L)^2+(y_J-y_L)^2}\)

\(\implies LJ = \sqrt{(3-(-7))^2+(-10-12)^2}\)

\(\implies LJ=\sqrt{584}\)

Therefore:

\(\begin{aligned}\implies \sf Perimeter & = \sf JK + KL + LJ\\& = \sqrt{369}+\sqrt{125}+\sqrt{584}\\& = 54.55580455...\\& = 54.56\:\: \sf units\:(2\:d.p.)\end{aligned}\)

The surface area of the cylinder will be \(968feet^{2}\)

The surface area of ​​a cylinder is the area occupied by its surface in three-dimensional space. It has no peaks. The area is shown in square units. For example cm2, m2, and so on. A cylinder can be seen as a set of circular disks that are stacked on top of each other. Since a cylinder is a three-dimensional body, it has both a surface and a volume.

The area of ​​the cylinder is defined as the sum of the curved surface and the area of ​​the two circular bases of the cylinder.

The surface area of ​​the cylinder = curved area + area of ​​circular bases

SA = \(2\)πr (h + r) square unit

Where, π (Pi) = \(3.142\) or = \(22/7\)

r = Radius of the cylinder

h = Height of cylinder

As we know, a cylinder has two types of surfaces, one is a curved surface and the other is a circular base. So the total area will be the sum of the curved area and the two circular bases.

Now if the cylinder has h=\(15\) feet and d=\(14\) feet or r=\(7\) feet

The surface area of cylinder will be:

SA=\(2\)π*\(7(15+7)\) \(feet^{2}\)

Hence the surface area of cylinder will be:

\(SA=2*22/7*7*22=968feet^{2}\)

On solving the provided question ,we can say that The statement "The number of new clients (x) is 149% of the number of old clients (y)" can be written mathematically as: x = 1.49y

A sequence is a grouping of "terms," or integers. Term examples are 2, 5, and 8. Some sequences can be extended indefinitely by taking advantage of a specific pattern that they exhibit. Use the sequence 2, 5, 8, and then add 3 to make it longer. Formulas exist that show where to seek for words in a sequence. A sequence (or event) in mathematics is a group of things that are arranged in some way. In that it has components (also known as elements or words), it is similar to a set. The length of the sequence is the set of all, possibly infinite, ordered items. the action of arranging two or more things in a sensible sequence.

The statement "The number of new clients (x) is 149% of the number of old clients (y)" can be written mathematically as:

The linear equation in the required form is: x - 1.49y = 0

What is linear equation?

A linear equation is a mathematical equation that describes a straight line in a two-dimensional plane. It is an equation of the form:

y = mx + b

Let's start by assigning variables to the given information. We are told that "the number of new clients (x) is 149% of the number of old clients (y)."

Using this information, we can write:

x = 1.49y

To write this equation in the form ax + by = c, we need to move all the variables to one side of the equation and simplify.

Subtracting 1.49y from both sides, we get:

x - 1.49y = 0

So the linear equation in the required form is:

Answer:

Starting with the equation:

(x + 1)^2 = 13/4

We can use the square root property, which states that if a^2 = b, then a is equal to the positive or negative square root of b.

Taking the square root of both sides, we get:

x + 1 = ±√(13/4)

Simplifying under the radical:

x + 1 = ±(√13)/2

Now we can solve for x by subtracting 1 from both sides:

x = -1 ± (√13)/2

Therefore, the solutions to the equation are:

x = -1 + (√13)/2 or x = -1 - (√13)/2

Answer:

  76 units

Step-by-step explanation:

You want the length of AC in the given triangular pyramid.

The Pythagorean theorem can be used to find the lengths of AD and CD.

  AD² + 40² = 41²

  AD² = 41² -40² = 81 . . . . . = 9²

and

  CD² +40² = 85²

  CD² = 85² -40² = 5625 . . . . . = 75²

It can also be used to find AC:

  AD² + CD² = AC²

  81 + 5625 = AC²

  AC = √5706 = 3√634 ≈ 76

The length of side AC is about 76 units.

The value of x is -3 and y is 7 for equilateral triangle having x+1, 2x+4 and 3x+y sides.

We can use the fact that an equilateral triangle has equal lengths on each of its three sides to determine the values of x and y.

Given:

First side=x+y

second side= 2x+4

third side=3x+y

An equilateral triangle has three equal sides, hence the following equations can be constructed:

x + 1 = 2x + 4

2x + 4 = 3x + y

Let's tackle each of these equations separately:

x + 1 = 2x + 4

We will subtract x from both sides and subtract 4 from both sides in order to solve this equation:

x + 1 - x = 2x + 4 - x

1 = x + 4

By taking 4 away from both sides, we arrive at:

1 - 4 = x + 4 - 4 , -3 = x

Therefore, x has been determined to be -3.

Now, substitute the value of x in the second equation:

2x + 4 = 3x + y

2(-3) + 4 = 3(-3) + y

-6 + 4 = -9 + y

-2 = -9 + y

y = -2 + 9

y = 7

So, we determined that y has a value of 7.

As a result, the values of x and y are, respectively, x=-3 and y=7

Answer:

Step-by-step explanation:

In an equilateral triangle all sides are equal.

So each of these sides (and their equations are equal to each other.)

To find x - set the first two (as they only involve x) equal to each other and solve.

x + 1 = 2x + 4

x -x + 1 = 2x - x + 4

1 = x + 4

1- 4 = x + 4 - 4

-3 = x

Then substitute -3 for x in the last equation to find y, also setting it equal to one of the other equations.

3(x) + y = x + 1

3(-3) + y = -3 + 1

-9 + y = -2

-9 + 9 + y = -2 + 9

y = 7

so x = -3 and y equal 7

Answer:

It is given that the volume of a cone = \(3\pi x^3\) cubic units

Volume of cone with radius 'r' and height 'h' = \(\frac{1}{3}\pi r^2h\)

Equating the given volumes, we get

\(3\pi x^3=\frac{1}{3}\pi r^2h\)

\(r^2h=3\) × \(3x^3\)

\(r^2h=9 x^3\)

It is given that the height is 'x' units.

Therefore, \(r^2x=9x^3\)

\(r^2=9x^2\)

Therefore, \(r=3 x\)

So, the expression '\(3 x\)' represents the radius of the cone's base in units.
