Answer:  x + 4y = 26 Slope = -0.500/2.000 = -0.250

 x-intercept = 26/1 = 26.00000

 y-intercept = 26/4 = 13/2 = 6.50000

Step-by-step explanation: x + 4y = 26

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 6.500 and for x=2.000, the value of y is 6.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 6.000 - 6.500 = -0.500 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -0.500/2.000 = -0.250

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  x+4y-26  = 0 and calculate its properties

Notice that when x = 0 the value of y is 13/2 so this line "cuts" the y axis at y= 6.50000

 y-intercept = 26/4 = 13/2  =  6.50000

When y = 0 the value of x is 26/1 Our line therefore "cuts" the x axis at x=26.00000

 x-intercept = 26/1  = 26.00000

3x – 4y = 30 Slope = 1.500/2.000 = 0.750

 x-intercept = 30/3 = 10

 y-intercept = 30/-4 = 15/-2 = -7.50000

Notice that when x = 0 the value of y is 15/-2 so this line "cuts" the y axis at y=-7.50000

 y-intercept = 30/-4 = 15/-2  = -7.50000

y = 0 the value of x is 10/1 Our line therefore "cuts" the x axis at x=10.00000

 x-intercept = 30/3  =  10

Answer:

What is the best window range for the x-values to determine the solution?

x-min=-10, x-max = 15

(L2) The Circumcenter Theorem states that the circumcenter of a triangle is equidistant from each vertex of the triangle.

The Circumcenter Theorem is a fundamental concept in geometry that states that the circumcenter of a triangle is equidistant from each of its vertices. In other words, the circumcenter is the point where the perpendicular bisectors of the sides of a triangle intersect.

The circumcenter plays a crucial role in the geometry of triangles, as it is the center of the circumcircle, which is the circle that passes through all three vertices of the triangle.

The circumcircle has several important properties, such as the fact that the length of the circumcircle's circumference is equal to twice the length of the triangle's longest side.

Step-by-step explanation:

This makes sense because the formula terms Probability Distributions are built upon one another, allowing us to utilise repeated reasoning to determine the value of Cn for any value of n.

Making generalisations using specific observations or data is known as inductive reasoning. Scientific research frequently bases ideas on patterns or trends that have been noticed. On the other hand, deductive reasoning entails applying broad concepts or rules to come to specific conclusions. It is frequently employed in logic and mathematics, where the premises are known to be valid and conclusions are reached by logical reasoning.

Using repeated reasoning we have:

C₁ = n = 1

C₋₁ = n = 1

C = 1

Cₙ in terms of C, C₁, and C₋₁:

Cₙ = 2C + C₁ + 3C₋₁

Substituting in the values we have for n = 1:

C₂ = 2(1) + 1 + 3(1) = 6

Now using n = 2, we have:

C₁ = n = 2

C₋₁ = n - 1 = 1

C = 1

Substituting in the formula again:

C₃ = 2(1) + 2 + 3(1) = 7

Now, for n = 3:

C₁ = n = 3

C₋₁ = n - 1 = 2

C = 1

C₄ = 2(1) + 3 + 3(2) = 11

This makes sense because the formula's terms are built upon one another, allowing us to utilise repeated reasoning to determine the value of Cn for any value of n.

Step-by-step explanation:

One right triangle is formed by:

Another similar right triangle is formed by:

Proportionality of similar sides:

First set of similar sides:

Second set of similar sides:

Now we can create proportions to solve for s, the length of the shadow:

18 / 6 = (15 + s) / s

(3 = (15 + s) / s) * s

(3s = 15 + s) - s

(2s = 15) / 2

s = 7.5

Thus, the length of the shadow is 7.5 ft.

Check the validity of the answer:

We can check our answer by substituting 7.5 for s and seeing if we get the same answer on both sides of the equation we just used to solve for s:

18 / 6 = (15 + 7.5) / 7.5

Step-by-step explanation:

The given diagram shows two similar right triangles.

Let "x" be the base of the smaller triangle. Therefore:

In similar triangles, corresponding sides are always in the same ratio. Therefore, we can set up the following ratio of base to height:

\(\begin{aligned}\sf \underline{Smaller\;triangle}\; &\;\;\;\;\;\sf \underline{Larger\;triangle}\\\\\sf base:height&=\sf base:height\\\\x:6&=(15+x):18\end{aligned}\)

Express the ratios as fractions:

\(\dfrac{x}{6}=\dfrac{(15+x)}{18}\)

Cross multiply and solve for x:

\(\begin{aligned}18x&=6(15+x)\\\\18x&=90+6x\\\\18x-6x&=90+6x-6x\\\\12x&=90\\\\\dfrac{12x}{12}&=\dfrac{90}{12}\\\\x&=7.5\end{aligned}\)

Answer:

Triangle ABC is congruent to triangle DFE.

Answer: The end behavior of (f - g)(x) can be found by analyzing the end behavior of f(x) and g(x).

As x approaches infinity, both f(x) and g(x) approach some constant value. Specifically, f(x) approaches infinity/4 = 0 and g(x) approaches 3/2.

Therefore, the end behavior of (f - g)(x) as x approaches infinity is:

(f - g)(x) = f(x) - g(x)

(f - g)(x) = x/4 - 3/2

(f - g)(x) = (x - 6)/4

As x approaches infinity, the numerator of (f - g)(x) (x - 6) will approach infinity, while the denominator (4) will remain constant. Therefore, the end behavior of (f - g)(x) as x approaches infinity is:

(f - g)(x) approaches infinity/4 = 0

Similarly, as x approaches negative infinity, both f(x) and g(x) approach some constant value. Specifically, f(x) approaches negative infinity/4 = 0 and g(x) approaches 3/2.

Therefore, the end behavior of (f - g)(x) as x approaches negative infinity is:

(f - g)(x) = f(x) - g(x)

(f - g)(x) = x/4 - 3/2

(f - g)(x) = (x - 6)/4

As x approaches negative infinity, the numerator of (f - g)(x) (x - 6) will approach negative infinity, while the denominator (4) will remain constant. Therefore, the end behavior of (f - g)(x) as x approaches negative infinity is:

(f - g)(x) approaches negative infinity/4 = 0

So, the end behavior of (f - g)(x) is that it approaches 0 as x approaches either infinity or negative infinity.

b. The labor-force participation rate is 60%.

According to the question,

Working age population- 100,000

Labour force - 60,000

Unemployed - 12000 instructions

a) The unemployment rate is the percentage of the labor force that is unemployed and it is calculated as follows:

Unemployment Rate = \(\frac{Number of unemployed People}{Labor force}\) × 100

When an unemployed population is 12,000 and the labor force is 60,000,

the unemployment rate is  = \(\frac{12000}{60000}\) × 100 = 20%

b) labor force participation rate is the percentage of working adult population that participates in labor either by actively looking for a job, or working. It is calculated as follows:

Labor Force Participation Rate = \(\frac{Labor force}{working age population}\) × 100

When the labor force is 60,000 and the working-age population is 100,000

Labor Force Participation Rate = \(\frac{60000}{100000}\) × 100 = 60%

What is perimeter?

The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimeters, meters, inches, and feet.

Given: The midpoints of the adjacent sides of a square are connected to form a new square. The perimeter of the original square is 16 inches.

As perimeter is 16 in, so the side is 4 in.

Each side of the new square is the hypotenuse of an isosceles right triangle with legs of length 2 inches.

\((2 in)^2 + (2 in)^2 = s^2\\s^2 = 8 in^2\\s = 2\sqrt{2} in\)

Answer: The diameter of Pool A is 7.32 meters. So, the diameter of Pool B is greater, and the circumference is greater by 0.56 meters.

Step-by-step explanation:

The diameter of a circle is double its radius.

Pool A has a radius of 12 feet - double that would be 24 feet, its diameter.

Next, convert this to meters:

\(24 * \frac{0.305}{1} = 7.32\)

The diameter of pool A is 7.32 meters.

The diameter of pool B is 7.5 meters.

The diameter of pool B is greater.

You can calculate the circumference of a circle by using this formula:

\(C = 2\pi r\), where r is the radius.

Divide 7.5 by 2 to get your radius of Pool B, which is 3.75, and solve for C:

\(C = 7.5\pi \\\\C = 23.561\)

Rounding to the nearest hundredth, the circumference for pool B is 23.56 meters.
