In mathematics, particularly in algebra, there are mainly two types of solutions for an equation: real and complex solutions.

Real solutions: These are type of solutions that are real numbers, which can be found by solving the equation algebraically. For example, if the equation is x² + 2x - 3 = 0, the real solutions are x = -1 and x = 3.

Complex solutions: These are solutions that are complex numbers, which can be found by solving the equation algebraically. Complex numbers are numbers that have both real and imaginary parts, represented by a + bi, where a and b are real numbers and i is the imaginary unit (i² = -1). For example, if the equation is x² + 1 = 0, the complex solutions are x = i and x = -i.

The triangle with sides 56 , 55 and 43 is acute triangle

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ABC

Now , the base of the triangle is BC

The measure of BC = 43

The height of the triangle is AB

The measure of AB = 55

The hypotenuse of the triangle is AC

The measure of AC = 56

Now , if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

On simplifying the equation , we get

BC² + AB² > AC²

Substituting the values in the equation , we get

43² + 55² > 56²

1849 + 3025 > 3136

The equation for a line that passes through the points (-5, 3) and (3, -3) is y=-3/4(x+1)

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Slope of line that passes through the points (-5, 3) and (3, -3)

m=-3-3/3+5

m=-6/8=-3/4

Now let us find y intercept.

3=-3/4(-5)+b

3=15/4+b

b=3-15/4

b=-3/4

So the slope intercept form is y=-3/4x-3/4

Hence, the equation for a line that passes through the points (-5, 3) and (3, -3) is y=-3/4(x+1)

The solution set, for instance, is the subset of a set of polynomials over a ring on which all of the polynomials formal disappear (evaluate to 0).

Plug in each value from the replacement set and evaluate both sides of the equation to determine the solution set from the replacement set. The value is a solution to the equation if the two sides are equal. One example: From the replacement set, choose the set with the solution 11 - 5w = 1.

The set of values that satisfy a given inequality is called a solution set. This indicates that the inequality will be satisfied by every value in the solution set and by no other value. Example: 2x + 3  7, where x is a natural number, is the solution.

Answer: To find the coordinates of P, we will use the part-to-whole ratio of 1 to 5. This means that the distance from A to P is 1/6 of the distance from A to B.

We can find the distance from A to B by using the distance formula:

d = √((x2-x1)² + (y2-y1)²)

where (x1, y1) and (x2, y2) are the coordinates of A and B, respectively.

So, the distance from A to B is:

d = √((1-(-9))² + (8-3)²) = √((10)² + (5)²) = √(100 + 25) = √125 = 5√5

Since P partitions AB with the ratio 1 to 5, the distance from A to P is 1/6 of the distance from A to B, which is (1/6) * (5√5) = √5

To find the coordinates of P, we will use this distance and the direction from A to B to find the coordinates of P.

The direction from A to B is:

(1 - (-9))/(8 - 3) = 10/5 = 2

So, the slope of line AB is 2. Therefore, the slope of line AP is -1/2 (perpendicular to AB)

We know that A = (-9, 3) and the slope of line AP = -1/2. We can use this to find the equation of the line AP:

y - 3 = -1/2(x + 9)

y = -1/2x - 3/2 + 3

y = -1/2x + 3/2

Since the point A is on the line, we can substitute the coordinates of A into the equation:

3 = -1/2*(-9) + 3/2

3 = 4.5

This is not true, so we can say that the equation is wrong.

To find the equation of line AP, we can use the point-slope form of a line:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line, and m is the slope of the line.

So, the equation of line AP is:

y - 3 = -1/2(x + 9)

Now we know that the point P is on the line AP and the distance from A to P is √5.

We can use this information to find the coordinates of P by moving along the line AP by √5 units in the direction of P.

To move in the direction of P, we need to move parallel to the line, which means we need to keep the slope of the line same.

So we can move

Notice when x increases by 1, y increases by $6?

When x goes from 1.5 to 2.5 gigabytes ( increase by 1 ), y increases from $65 to $71. That's a $6 increase for x increasing by 1 gigabyte.

In addition, when x goes from 2.5 to 3.5 gigabytes ( increase by 1), y increases from $71 to $77. This is also a $6 increase for x increasing by 1 gigabyte.

Yet...

65 / 1.5 doesn't equal 71 / 2.5

65 / 1.5 = 43 1/3

71 / 2.5 = 28.4

43 1/3 [tex]\neq[/tex] 28.4, so there is no proportion

Answer: No.

Step-by-step explanation:

      In a proportion relationship, y = kx. In other words, x times the constant of proportionality will equal y. Without a given constant of proportionality, we can use k =[tex]\frac{y}{x}[/tex]. In all instances, y divided by x should equal the same value (k). We will see if this stands true for all the given values.

The law of Sines is used to find the length of the third side of an obtuse triangle. The value of a i.e., third side length is equals to 6.065 units.

In geometry, obtuse triangles are defined as the triangles with an obtuse angle, which is an angle measuring greater than 90°. According to the law of sines of triangles if a triangle has sides a, b, and c, and angles A, B, and C, where side a has opposite angle A, side b has opposite angle B, and c has opposite angle C, then

sinA/a = sinB/b = sinC/c

The sum of all interior angles of a triangle is 180°. If we have two of the sides of an obtuse triangle, and two of the angles of an obtuse triangle, then we can use the law of sines to determine the third side of the obtuse triangle. Let's consider an obtuse triangle ABC present in above figure. We want to find the length of side a. We have, AB = 8 units , AC = 5 units, BC = a units.

∠A = 32° , ∠B =40° , ∠C = obtuse angle

=>∠C = 180°-∠A - ∠B = 180°- 32°- 40° = 108°

From above formula, sinA/a = sinB/b= sinC/c

=> sin 32°/5 = sin 40°/a = sin 108°/8

=> a = 5 sin 40°/ sin 32°

=> a = 5×0.6428/0.5299

=> a = 6.06529533874

=> a ≈ 6.065
