The perimeter of the triangle passing through the points A, B, C is 27.5 cm.

A triangle's perimeter and side lengths are measured in the same unit. If the sides' lengths are measured in a different unit, first convert them to that unit. Example 1: Calculate the triangle's perimeter from the information provided. A perimeter is a closed path that encloses, surrounds, or delimits a one-dimensional length or a two-dimensional shape. The circumference of a circle or an ellipse is its outermost boundary.

There are many uses in real life for perimeter calculations. The length of fence needed to enclose a yard or garden is known as the calculated perimeter.

From the figure,

The triangle is passing through the points A(4, 0), B(-6, 5), C(3, 3)

By using distance formula, we have to calculate the lengths of AB, BC, CA

Length of AB=√(-6-4)²+(5-10)²

=√125

Length of BC=√(3+6)²+(3-5)

=√85

Length of CA=√(3-4)²+(3-10)²

=√50

The perimeter of a triangle=AB+BC+CA

=√125+√85+√50

=11.18+9.22+7.07

=27.47≈27.5

Therefore, the perimeter of the triangle is 27.5 cm.

Answer:

Below

Step-by-step explanation:

Question 1:

The quadratic equation is of the form ax^2 + bx + c = 0, where a, b, and c are constants. If one solution of the equation is 7-13i, the other solution must be the complex conjugate of 7-13i, which is 7+13i. To find the complex conjugate of a complex number, you simply need to change the sign of the imaginary part of the number. In this case, the complex conjugate of 7-13i is 7+13i.

Question 2:

1. (4-3i) (-7+21)

To add two complex numbers, we need to add their real parts and imaginary parts separately. In this case, we have:

(4-3i) (-7+21)

= (4 - 7) + (-3i + 21)

= -3 + 18i

2. (-7+6i)+(2-3i)+(4+5i)

To add multiple complex numbers, we can add them one at a time using the same procedure as before. In this case, we have:

(-7+6i)+(2-3i)+(4+5i)

= (-7+2) + (6i - 3i) + (4 + 5i)

= -5 + 3i + 4 + 5i

= -1 + 8i

3. (-6-i)/4-2i

To divide two complex numbers, we need to multiply the numerator and denominator by the complex conjugate of the denominator. In this case, we have:

4. (-6-i)/4-2i

= (-6-i)(4+2i)/(4-2i)(4+2i)

= (-24 - 2i + 6i - i^2)/20

= (-24 + 4 -1)/20

= (-21)/20

= -1.05 - 0.05i

5. (-2-7i)(-2+7i)

To multiply two complex numbers, we use the FOIL method, which involves multiplying the First, Outer, Inner, and Last terms separately and then adding the results. In this case, we have:

(-2-7i)(-2+7i)

= (-2 * -2) + (-2 * 7i) + (-7i * -2) + (-7i * 7i)

= 4 + (-14i) + 14i + 49

= 4 + 49

= 53

6. (5-3i)-(-2-6i)

To subtract two complex numbers, we need to add the first number to the opposite of the second number. In this case, we have:

(5-3i)-(-2-6i)

= (5-3i) + (2 + 6i)

= 7 + 3i

This is the final answer for each of the problems.

There were 425 guests at a hotel. 170 guests ordered food. 40 percentage of the guests ordered food.

A percentage is a fraction of a whole in mathematics, which is denoted by the symbol per 100. A single unit out of a hundred, or one hundredth of something, is represented as a single percent, such as 1%. The Latin phrase per centum, which means by the hundred, is where the word percent originates. Percentage does really refer to a hundredth or 1/100 of something.

Given,

Total number of guests = 425

Guest who ordered food = 170

For percentage,

Value/ Total × 100%

170/425 × 100%

0.4 × 100%

The bijection could be defined from the set of numbers and it is proved.

We can define a bijection f from S to T as follows: for any integer x in S, let f(x) = x + 1.

To show that f is a bijection, we need to prove that it is both injective and surjective.

To prove that f is injective, suppose f(x) = f(y) for some x, y in S. Then x + 1 = y + 1, which means x = y. Thus, f is injective.

To prove that f is surjective, let y be an arbitrary element of T. Since y is odd, we can write y = 2n + 1 for some integer n. Now consider the element x = 3n in S. We have f(x) = x + 1 = 3n + 1 = y, so f is surjective.

Therefore, f is a bijection from S to T, so |S| = |T|.

To determine which region represents the solution to a system of linear inequalities, you need to graph each inequality on the same coordinate plane and then find the intersection of the regions that satisfy each inequality. This intersection is the solution to the system of linear inequalities, as every point in this region satisfies all of the inequalities in the system.

To graph the solution, you can use a number line for each variable and plot the inequalities as points or lines on the coordinate plane. For example, if the system of linear inequalities is given by the equations y > 2x + 3 and y < -x + 5, you can plot the lines y = 2x + 3 and y = -x + 5 on the coordinate plane and find the intersection of the two lines. This intersection represents the solution to the system of linear inequalities, as every point in this region satisfies both inequalities.

Another way to find the solution to a system of linear inequalities is by using algebra to solve the system. This involves writing the equations in standard form, eliminating variables, and solving for the remaining variable. The solution can then be written as a set of ordered pairs that represent the points on the coordinate plane that satisfy the system of linear inequalities.

In either case, the solution to a system of linear inequalities is the region of the coordinate plane that satisfies all of the inequalities in the system.

The value of x from the given isosceles triangle GHJ is 5.

Isosceles triangles are those triangles that have at least two sides of equal measure and two base angles are equal.

In the given isosceles triangle GHJ, GJ=GH, ∠G=38° and ∠J=(14x+1)°.

Since, sides GJ=GH

∠J=∠H

Now, ∠G+∠J+∠H=180° (Angle sum property of a triangle)

⇒ 38°+(14x+1)°+(14x+1)°=180°

⇒ 28x+40°=180°

The length of one side is 20 ft and the other side of the yard is 33 ft.

Let the length of the side opposite to the house be x ft.

We know that the yard to be fenced is rectangular. Hence the opposite sides of the yard are going to be equal.

It is given that the side opposite to the wall is 13 ft less than the length f the other two sides.

Hence the length of the side adjacent to the house will be

(x + 13) ft

The fencing needs to be done on these three sides. We already know that the length that has been fenced is 86 ft.

Hence, we get

x  +  x + 13  +  x + 13  =  86

or, 3x + 26 = 86

or, 3x = 86 - 26

or, 3x = 60

or, x = 60/3

or, x = 20.

Hence the length of one side is 20 ft and the length of the other side is

If you take the same number and times by 7 then subtract 8, you get (7x - 8).

Set the equations equal to each other:

3x + 5 = 7x - 8

The equation of the line that passes through the point (−11,−14) is y = x - 3.

What is the slope of the line?

A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x).

We have,

The line that passes through the point (−11,−14)

With Slope (m) = 1,

The general equation of a straight line is

y = mx + c,

where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

so here,

y = mx + c,

(-14) = 1(-11) + c

c = -14 + 11

c = -3

The equation becomes:

y = x - 3.

The minimum cost for the area can be fenced is $1920

It is given that the area of the rectangular field is 900 m²

Let the length of one side of the field be x m

Therefore, the length of the other side will be

900/x

The perimeter of the rectangular field

= 2(length + breadth)

= 2(x + 900/x)

= 2x + 1800/x  m

Therefore, the cost of fencing will be

$(32x + 28800/x )

Let f(x) = 32x + 28800/x

We need to minimize f(x)

Differentiating with respect to x and equating it to 0 gives us

32 - 28800/x² = 0

or, x² = 28800/32

or, x² = 900

or, x = 30

This is because the length cannot be negative hence -30 cannot be a value

Now

f''(x) = 57600/x³

f''(30) = 2/1333

Since f"(x) is positive, x = 30 is the minimum value of x for which the cost is minimum.
