What is the length of segment AC?

For this case we have the following expression:

[tex]-1.5x-3 <5.5[/tex]

Adding 3.1 to both sides of the inequality:

[tex]-1.5x <5.5 + 3\\-1.5x <8.5[/tex]

Dividing between -1.5 on both sides of the inequality, keeping in mind that the sign changes direction:

[tex]x> \frac {8.5} {- 1.5}\\x> -5.66666[/tex]

Answer:

[tex]x> -5.66666[/tex]

x> -5.6 periodical number

Answer:

{x| x > -5.667}

Step-by-step explanation:

We have the following inequality[tex]-1.5x -3 < 5.5[/tex]

We must solve the incus for the variable x

[tex]-1.5x -3 < 5.5[/tex]

Add 3 on both sides of inequality

[tex]-1.5x -3 +3 < 5.5 +3\\\\-1.5x<5.5 +3\\\\-1.5x<8.5[/tex]

Multiply by -1 both sides of the inequality

[tex](-1)*(-1.5)x<8.5*(-1)\\\\1.5x>-8.5[/tex]

Divide between 1.5 both sides of the inequality

[tex]\frac{1.5}{1.5}x>-\frac{8.5}{1.5}\\\\x > -5.667[/tex]

The answer is:

[tex]x > -5.667[/tex]

{x| x > -5.667}

Answer:

81 π / 254.469004941 ft²

Step-by-step explanation:

Area of circle = π × r²

Half the diameter = radius

18 ft ÷ 2 = 9 ft

9 ft = radius

Area of circle = π × 9²

Area of circle = 81π

Area of circle = 81 π / 254.469004941

Area of circle =

To find the area of a circle with a diameter of 18 feet, first find the radius (9 feet), then apply the formula A = πr². The area is approximately 254.47 square feet.

To find the area of a circle, you need to use the formula:

A = πr²

Given the circle's diameter is 18 feet, we first need to find the radius. The radius (r) is half the diameter:

r = D / 2 = 18 ft / 2 = 9 ft

Now, substitute the radius back into the area formula:

A = πr² = π(9 ft)² = π(81 ft²)

Using the approximation π ≈ 3.14159, we get:

A ≈ 3.14159 × 81 ft² ≈ 254.47 ft²

Therefore, the area of the circle is approximately 254.47 square feet.

Answer:

Step-by-step explanation:

Let's say the circulation for newspaper 1 is X. Then the circulation for newspaper 2 is smaller, by 382, so we can call it (X - 382). It's really 382,000 of course, but we can leave off the extra zeros for now.

Anyway, the total of both would have to be X + (X - 382) = 2492. This simplifies to:

2X - 382 = 2492

If you can solve that equation, you'll have the circulation for newspaper 1, in thousands.

Does this give you a push in the right direction?

The circulation of newspaper 1 is 1437 thousand and the circulation of newspaper 2 is 1055 thousand.

This question requires us to use a system of linear equations to solve for the circulation for each newspaper. Let's denote the circulation of newspaper 1 as x and the circulation of newspaper 2 as y.

We have two pieces of information that help us form two separate equations. The first piece of information is that newspaper 1's circulation is 382 thousand more than newspaper 2's circulation, so we can express this as:

x = y + 382

The second piece of information is that the combined circulation of both newspapers is 2492 thousand. Therefore, we form the equation:

x + y = 2492

We can now replace x in the second equation with the value of x from the first equation (y + 382) to solve for y:

(y + 382) + y = 2492

Solving that, we find that y (the circulation of newspaper 2) is 1055 thousand. Substituting y into the first equation, we can solve for x (the circulation of newspaper 1), which is 1437 thousand.

Final answer:

The point (-5, 12) lies on the circle with a radius of 13 and a center at the origin because it satisfies the equation [tex]x^2 +[/tex] [tex]y^2 = 13^2.[/tex]

Explanation:

The student is asking which point lies on the circle with a center at the origin and a radius of 13. To determine if a point lies on a circle defined by the equation [tex]x^2 + y^2 = r^2,[/tex] where r is the radius, we plug the point's coordinates into the equation and see if they satisfy it.

Let's examine each point:

[tex](-5, 12): (-5)^2 + (12)^2 = 25 + 144 = 169[/tex]

[tex](13, 13): (13)^2 + (13)^2 = 169 + 169 does not equal 169[/tex]

[tex](6, -7): (6)^2 + (-7)^2 = 36 + 49 = 85 does not equal 169[/tex]

Answer:

Let 'x' and 'y' be two different numbers.

Leila says that 75% of a number will always be greater than 50% of a number. The inequality that represents this statement is the following:

0.75x > 0.5y

Let x = 100 and y=200. We have that:

0.75(100) > 0.5(200)

75 > 100 ❌ INCORRECT ❌

Given that we found a case in which 75% of a number is not greater than 50% of a number, we can conclude that Leila's claim is incorrect.

Answer:

The regression line fits the data well. Problem can be when there is a trend, like exponential growth, but someone still wants to use linear regression. Although in this case it seems to be okay. In other words, the data points can be found under or over the line randomly. In a problematic case is when for example, there are 5 data points next to each other under the line. Usually companies don't make profit when they're first starting.

First  I focused on 3 or more points that were collinear to each other.  Collinear means that when you connect these points, you get a straight line.  These points are at months 1, 2, 3, and 9.  Then of these points, I chose 2 points to find the slope between them.

Point 1 = (1, 0)

Point 2 = (2, 2.5) or  (2, 2500)         because profit is measured in thousands

These are the first two points.

Slope = (2500 - 0) / (2 - 1)

Slope = 2500 / 1

Slope = 2500

Then I plug in the slope and values of point 1 into the slope-intercept form of the line.

y = mx + b

0 = 2500(1) + b

Now we have to Solve for b.

0 = 2500 + b

-2500 = b

Plug in this value of b into the slope intercept form of the equation to get the best fit line.

 y = 2500x - 2500

Answer:

i agree with the guy above

Step-by-step explanation:

For this case we have that by definition of properties logarithm is met:

[tex]log_ {b} (x) -log_ {b} (y) = log_ {b} (\frac {x} {y})[/tex]

So, rewriting the expression we have:

[tex]log (\frac {9x} {2 ^ 3}) = 3\\log (\frac {9x} {8}) = 3[/tex]

By definition of logarithm we have to:

[tex]log_ {b} (x) = y[/tex]is equivalent to[tex]b ^ y = x[/tex]

So:

[tex]10 ^ 3 = \frac {9x} {8}\\9x = 8 * 10 ^ 3\\9x = 8 * 1000\\9x = 8000\\x = \frac {8000} {9}[/tex]

There are [tex]4.93\times 10^{22}[/tex] copper atoms in 5.2 gram of metallic copper.

Step-by-step explanation:

Start by finding the number of moles of copper atoms in that 5.2 gram of metallic copper. Look up the relative atomic mass of copper on a modern periodic table.

In other words, the mass of one mole of copper atoms is 63.546 gram.

[tex]M(\mathrm{Cu}) = \rm 63.546\; g\cdot mol^{-1}[/tex].

How many moles of copper atoms in that 5.2 gram sample?

[tex]\displaystyle n = \frac{m}{M} =\rm \frac{5.2\; g}{63.546\; g\cdot mol^{-1}} = 0.0818305\; mol[/tex].

Now, how many atoms is [tex]\rm 0.0818305\; mol[/tex]?

The Avogadro's Number gives the number of particles in one mole:

[tex]N_A \approx \rm 6.022\times 10^{23}\;mol^{-1}[/tex]. (Encyclopedia Britannica)

There are [tex]6.022\times 10^{23}[/tex] particles (a very large number) in one mole. [tex]\rm 0.0818305\; mol[/tex] of copper atoms will thus contain

[tex]N = n\cdot N_A \approx \rm 0.0818305\; mol\times 6.023\times 10^{23}\;mol^{-1} \approx 4.93\times 10^{22}[/tex]
