To find the population of a city next year, we multiply its current population by 1.043. By what percent does the population increase per year?

The relation:

(9, -1) (4,2) (5,3) (8, -1) (3, 0)

Is a function, because each element of the domain appears only once.

A relation maps elements from a set, called the domain, into elements from another set, called the range.

Such that the element x being mapped into the element y is written as:

(x, y).

A relation is a function only if each element in the domain is mapped into only one element of the range.

Here we have the relation:

{  (9, -1) (4,2) (5,3) (8, -1) (3, 0)}

We can see that no element of the domain appears twice, so yes, this is a function.

The slope of the perpendicular line to the equation 5x - 4y = -24, is: 4/5.

The slope values of two lines which lie perpendicular to each other on a coordinate plane are always negative reciprocals to each other.

Rewrite the equation, 5x - 4y = -24 in slope-intercept form:

5x - 4y = -24

-4y = 5x - 24

Divide both sides by -4

-4y/-4 = 5x/-4 - 24/-4

y = -5/4x + 6

The slope of y = -5/4x + 6 is -5/4. The negative reciprocal of -5/4 is 4/5. Thus, the slope of the line that is perpendicular to the equation of the given line is: 4/5.

What is a Parallelogram ?

A unique variety of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.

Parallelograms' characteristics

(1) The opposing sides of a parallelogram are parallel to one another. In this case, AB || CD and AC || BD

(2) A parallelogram has equal-length opposing sides. In this case, AB = CD and AC = BD

(3) In a parallelogram, the measurements of the opposing angles are equal. In this case, A Equals C and B = D.

(4) The total of all the angles of a parallelogram, like all other quadrilaterals, is 360°.

(5) A parallelogram has neighboring or contiguous angles that sum to 180 degrees. As a result, A + B, B + C, C + D, and D + A all equal 180 degrees.

(6) A parallelogram's diagonals cut each other in half. In this case, OA = OC and OB = OD

(7) The parallelogram in the figure is split into two congruent triangles by the diagonals AC and BD.

The diagonals of a parallelogram bisect each other AC = 2 CE

Substitute AC= 50 into AC = 2CE = 50 = 2CE

Calculate 50 = 2 CE=>  CE = 25

The diagonals of a parallelogram bisect each other BD = 2DE

Substitute BD= 30 into BD = 2DE =>  30 = 2DE

Calculate 30 = 2DE  => DE = 15

Opposite sides of parallelogram are congruent AB = CD

Substitute AB = 18 into AB = CD =>  CD = 18

Perimeter of a triangle PΔCDE = CE + CD + DE

Substitute  CE = 25, DE = 15, CD = 18.

PΔCDE = CE + CD + DE

PΔCDE = 25+ 18 + 15

The sphere's radius is 5, and its center is at (0, 3, -4).

A sphere is a geometrical object that resembles a two-dimensional circle in three dimensions.

In three-dimensional space, a sphere is a collection of points that are all located at the same distance from a single point.

The radius of the sphere is denoted by the letter r, and the given point is its center.

List a few typical sphere examples from everyday life.

In everyday objects, sphere shapes can be found in the form of marbles, balls, oranges, yarn, and bubbles.

So, the center and radius of the sphere will be:

We have the sphere's equation, which is given by and has a radius of r.

(x - h)² + (y - k)² + (z - l)² = r² ...(1)

We must convert the following equation in order to determine the center and radius of the provided sphere.

x² + y² + z² - 6y + 8z = 0

By combining the x, y, and z terms and filling in the square, we obtain

x² + (y² - 6y + 9) +(z² + 8z + 16) = 9 + 16

(x - 0)² + (y - 3)² + (z + 4)² = 52

So, the sphere's center is at (0, 3, -4) and its radius is 5.

A right triangle is a triangle with one angle at a right angle, meaning that two of its sides are perpendicular. It is also known as a right-angled triangle, an orthogonal triangle, or more commonly as a rectangled triangle.

11)Let the given triangle is a right angle triangle.

So we can use trigonometric ratio,

[tex]tan(45) = \frac{x}{13} \\x = 13(tan(45))\\x = 13[/tex]

Using this to find the value of y.

[tex]sin(45) = \frac{x}{y} \\sin(45) = \frac{13}{y} \\y = \frac{13}{sin(45)} \\y = 18.4[/tex]

So, the values of x and y are x = 13 and y = 18.4.

12) The given triangle is a right angle triangle.

So we can use trigonometric ratio,

Step-by-step explanation:

2×length + 2×width = 204 cm

length = x

width = 3×(x + 2)

as consecutive even integers are always spaced out by 2 (2, 4, 6, ...).

we are using these 2 equations in the first main equation :

2×x + 2×3×(x + 2) = 204

2x + 6x + 12 = 204

8x + 12 = 204

8x = 192

x = 192/8 = 24

length = x = 24 cm
