Solve the inequality for x and identify the graph for its solution |x+3|>2

Answer: x = 50°

Step-by-step explanation:

As you can see in the triangle, the two sides are congruent. One of the angles next to the congruent side is 50 degrees. Therefore the other angle also has to be 50 degrees.

Answer:

X=50°

Step-by-step explanation:

Money spent on playstation games per week: =$8169861

Money spent on other video games per week: = $5542467

Step-by-step explanation:

Hi to answer this first, we have to calculate how much Americans spend on non Playstation video games. So, we have to subtract the money spent on Sony Playstation games to the total money spent:

$1958904.00-$1167123.00= 791781 on other video games per day

Now, since each week has 7 days. We have to multiply each daily amount by 7.

Money spent on playstation games per week: $1167123.00 x 7=8169861

Money spent on other video games per week: $791781 x 7= 5542467

The Equation representing the following inequality will be 2x + 8 < -18

In the given question, it is stated that a number is 8 more than twice a number that is less than -18.

Let the number be x.

The twice of a number = 2x

A number eight more than twice a number = 2x +8

With the following statements,  we get the Number = (2x+8). Also, we have a condition that this new number is lesser than -18. So we get our equation,

                 =>  2x + 8 < -18

Hence, This  2x + 8 < -18 represents the inequality mentioned in the question stating that a two number is created in which it is lesser than -18.

For given question,

We need to find  the population variance of the following set of numbers: 3, 5, 8, 9, 10

The formula for the Population variance is,

[tex]\sigma = \frac{\sum (x-\bar x)^2}{N}[/tex]

Here,

[tex]\bar x[/tex] = sample average

x = individual values in sample

N = count of values in the sample.

For given question,

[tex]\bar x=\frac{3+ 5+ 8+ 9+ 10}{5} \\\\\bar x=7[/tex]

Using the formula for variance,

[tex]\sigma = \frac{1}{5} [(3-7)^2 + (5 - 7)^2 + (8 - 7)^2 + (9 - 7)^2 + (10 - 7)^2]\\\\\sigma = \frac{1}{5} \times 34\\\\\sigma = 6.8[/tex]

We get the equation for the points of the data as x  y + 6 = 0

We are given the data as:

10            - 16

11             - 17

12            - 18

13            - 19

We need to find the equation for the data.

Slope = ( - 17 + 16 ) / ( 11 - 10)

m = - 1 / 1 = - 1

Now, the equation will be:

y - y₁ = m (x - x₁)

Substituting the values, we get that:

y + 16 = - 1( x - 10)

y + 16 = - x + 10

x + y + 16 - 10 = 0

x + y + 6 = 0

The height of the mountain using the angles of elevation is 2.346 miles

let

x = distance from the mountain to your current position

h = height of the mountain

Therefore, using trigonometric ratios,

angle of elevation of the current position to the mountain = 8°

angle of elevation of the former position to the mountain = 4.5°

Therefore,

tan ∅ = opposite / adjacent

where

∅ = angle of elevation

tan 8  = h / x

tan 4.5 = h / x + 13

Hence,

x tan 8 = h

(x + 13) tan 4.5 = h

using substitution,

x tan 8  = (x + 13) tan 4.5

x tan 8 = x tan 4.5 + 13 tan 4.5

0.1405408347x = 0.07870170682x + 1.02312218872

0.1405408347x - 0.07870170682x =  1.02312218872

0.0613x = 1.02312218872

x = 1.02312218872 / 0.0613

x = 16.6900489396

x = 16.690 miles

Therefore,

h = 16.6900489396 × tan 8

h = 16.6900489396 × 0.1405408347

h = 2.34561947798

The constant of proportionality is $0.50.

A mathematical constant is a significant integer whose value is determined by an explicit definition. It is frequently denoted by a symbol or by the names of mathematicians to make it easier to use in a variety of mathematical situations.

The amount paid by Rocko is $12.50 for 25 game tickets.

The amount paid by Rocko is $17.50 for 35 game tickets.

A proportional relation can be written as:

y = k × x

where k is a constant, y is the cost, and x represents the number of tickets purchased in this instance.

Substituting the values, for Rocko

$12.50 = k × 25

Therefore

k = $12.50 / 25

k = $0.50

For Louisa,

$17.50 = K × 35

K = $17.50 / 35

K = $0.50

The Volume generated when the region between the curves is rotated around the y - axis is 1216500335.46

Volume of the curves:

The volume of the solid formed by revolving the region bounded by the curve x = f(y) and the y-axis between y = c and y = d about the y-axis is given by

V = π ∫dc [f(y)]2dy.

The cross-section perpendicular to the axis of revolution has the form of a disk of radius R = f(y).

Given,

y = x³

Here we have to find the volume along to the y axis.

With limit as y = 0 and y = 27.

When we apply the values it can be written as,

=>[tex]V=\pi \int\limits^0_{27} {(x^3)^2} \, dx[/tex]

[tex]\implies V=\pi \int\limits^0_{27} {(x^6)} \, dx[/tex]

The dimension which this rug should have is 23 feet × 13 feet.

Mathematically, the area of a rectangle can be calculated by using this formula;

A = LW

Where:

Let x represent the width of this rug.

Also, the dimension of this rug is given by:

299 = (29 - 2x) × (19 - 2x)

299 = (29 - 2x)(19 - 2x)

Evaluating the equation, we have:

299 = 551 - 58x - 38x + 4x²

4x² - 58x - 38x + 551 - 299 = 0

4x² - 96x + 252 = 0

Dividing all through by 4, we have:

x² - 24x + 63 = 0

x² - 21x - 3x + 63 = 0

x(x - 21) - 3(x - 21) = 0

(x - 3)(x - 21) = 0

x = 3 or 21 feet.

Note: The plausible solution is x = 3.

Therefore, the width and length of this rug is given by:

Length = 29 - 2(3)

Length = 29 - 6

Length = 23 feet.

Width = 19 - 2(3)

Width = 19 - 6

Width = 13 feet.

Step-by-step explanation:

As we can see in the diagram, the triangle is a right-angled triangle, meaning that one of the angles inside the triangle has a measure of 90°.

Whenever we have a right-angled triangle and are given the lengths of two of its sides, and we are asked for the length of the third side, we must use the Pythagorean theorem, which states that:

[tex]\boxed{\mathrm{a^2 + b^2 = c^2}}[/tex],

where:

c = hypotenuse (longest side, opposite to 90° angle)

a, b = the two other sides of the triangle.

In this question, we are asked for the value of x, which is the hypotenuse of the given triangle, while the lengths of the other two sides are 15 and 36.

Therefore, using the Pythagorean theorem, we get:

[tex]15^2 + 36^2 = x^2[/tex]

⇒ [tex]x = \sqrt{36^2 + 15^2}[/tex]
