Answer:

Slope is [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Rearranging the equation:

[tex]4x - 20 = 16y[/tex]

The coefficient of y needs to be '+1' for the above equation to be considered as the slope-intercept form:

Dividing both sides of the equation by '16':

[tex]\frac{16}{16}y = \frac{1}{16}(4x -20)[/tex]

[tex]y = \frac{4}{16}x - \frac{20}{16}[/tex]

Divide the numerator and denominator present in the coefficient of x  by the Highest Common Factor '4'. Also divide the numerator and denominator present in the coefficient of 'non-x' term by the Highest Common Factor '4':

[tex]y = \frac{1}{4}x - \frac{5}{4}[/tex]

The simplified form of the slope-intercept of the equation has been achieved. The coefficient of x is the slope of the graph:

Let's find the domain of the function.

We were given: f(x) = 9 - 5/(x^4)

The domain of a function is a group of values that are valid within the function. The domain could range from (-∞, ∞)

However, since we have a fraction, there will be a limit to the range of values.

In this case, we will have to find what value the variable "x" can't be.

Since we are analyzing the "5/(x^4)" part of the function, we know that fractions can't have a denominator of 0. This means that the denominator can't equal zero.

x^4 ≠ 0

Solve for "x" by taking the root of both sides of the equations.

x ≠ 0 Therefore x can't equal 0.

This means that the value of "0" will not be in our domain, making our domain from:

(-∞, 0)∪(0, ∞)

The above means that we are including all the values (due to the use of infinity), except for the value 0.

Answer:

(-∞, 0)∪(0, ∞)

          Ted's

          eye level

Let d be the distance the dog needs to walk to get to the donut. We can use trigonometry to solve for d.

Since the angle of depression from Ted's line of sight to the dog is 40 degrees, the angle between the ground and Ted's line of sight is 90 - 40 = 50 degrees.

We can use the tangent function to find d:

tan(50) = opposite / adjacent

The opposite side is the height of Ted's eye level above the ground, which is 16 feet. The adjacent side is d, the distance the dog needs to walk to get to the donut.

tan(50) = 16 / d

d = 16 / tan(50)

d ≈ 12.6 feet

How to find the Area of the Polygon with n-sides?

For finding the area of a polygon which is not regular or its formula is not defined, we split the figure into triangles, squares, trapezium, etc. The purpose is to visualize the given geometry as a combination of geometries for which we know how to calculate the area. We then calculate the area for each of the part and then add them up to obtain the area of the polygon.

Here, we have given a polygon in the combination of a square and a triangle.

So, to find an area of the polygon we need first to find the area of square and triangle.

Area of Polygon Formulas:

Name of the Polygon Area Formula

Triangle = 1/2 × base × height

Square = (side)²

Area of Square = (13)²

= 169 unit².

Area of Triangle = 1/2 × base × height

To find base:

(height)² + (base)² = (hypotenuse)²

(13)² = (11)² + (base)²

169 = 121 + (base)²

(base)²  = 169 - 121

base = √48 = 6.9

Area of Triangle = 1/2 × (6.92) × 11

= 38.06 unit².

Area of Polygon = Area of Square  + Area of Triangle

=  169 + 38.06

= 207.06 unit².

Therefore, the area of the polygon is  207.06 unit².

The scale factor of the dilation from △ABC to △A"B"C" is 416.

What is scale factor?

A scale factor is defined as the ratio of the scale of a given original object to the scale of a new object that is its representation but of a different size (bigger or smaller)

The scale factor of a dilation is equal to the ratio of the lengths of corresponding sides of the preimage and the image.

In this case, the dilation from △ABC to △A'B'C' has a scale factor of D(13), and the dilation from △A'B'C' to △A"B"C" has a scale factor of D(32). To find the scale factor of the dilation from △ABC to △A"B"C", we need to multiply these two scale factors:

D(△ABC to △A"B"C") = D(13) * D(32)

D(△ABC to △A"B"C") = 13 * 32

D(△ABC to △A"B"C") = 416

So, the scale factor of the dilation from △ABC to △A"B"C" is 416.

This means that the lengths of corresponding sides of △ABC and △A"B"C" are related by a factor of 416.

The relative frequency of an event is a way to estimate the probability of that event happening.

For example, if you spin a spinner 50 times and the spinner lands on red 20 times, the relative frequency of getting red would be 20/50 = 0.4. This is a statistical estimate of the probability of the spinner landing on red, and it's based on the limited number of trials (spinning the spinner 50 times). As you increase the number of trials, the relative frequency will become a more accurate estimate of the true probability of the event. So if you spin the spinner 100 times instead of 50 times, and the spinner lands on red 40 times, the relative frequency would be 40/100 = 0.4. This shows that as the number of trials increases, the relative frequency becomes a better estimate of the true probability of the event. The reason for this is that the more trials you have, the more representative your sample is of the population, and the closer your estimate will be to the true probability of the event. In this case, the true probability of the spinner landing on red is unknown, but as you spin it more times, the relative frequency will approach the true probability, providing a more accurate estimate.

The volume of the cone = 0.262 feet³.

The word "cone" is derived from the Greek word "konos," which denotes a peak or a wedge. Apex and base both refer to the pointy end, which is referred to as the apex. A cone is a three-dimensional geometric structure with a smooth transition from a flat, generally circular base to the apex or vertex, a point that creates an axis to the base's center.

Given that,

base of the cone = 1 foot

thus, radius (r) = 0.5 foot

altitude = 1 foot

thus, volume (V) = 1/3 πr²h

or, V = 1/3 π × (0.5)² × 1

or, V = 0.262 feet³

To find a percentage of a whole, you first need to know exactly what you're measuring. For instance, if 38 people in your community have library cards, and you wish to work out the percentage of library card holders in the population, you'll first need to know the total size of your community.

A percentage of a total is equal to the subset of a total divided by the total, then multiplied by 100. If your community has 230 people in it, you can calculate the percentage of people with a library card. First, you divide 38 by 230, then multiply that total by 100.

38/230 = .165 .165 x 100 = 16.5

Therefore 16.5 percent of the people in your community have a library card.

A fraction has two parts, a numerator on the top and a denominator on the bottom. Any percentage can be expressed as a fraction with the percentage value as the numerator and 100 as the denominator. So 80 percent is also 80/100. You can use this to convert a fraction into a percentage as well.

For example, to turn the fraction 4/25 into a percent, you'll need a fraction with 100 as the denominator. So you'll need to multiply the denominator by 4 since this will produce 100. You then need to also multiply the numerator by the same amount.

4/25 = (4 x 4)/(25 x 4) = 16/100

You now have a fraction of 100, so you can convert it to a percentage quite easily: 16/100 is equal to 16 percent. Here's another example:

3/5 = (3 x 20)/(5 x 20) = 60/100 = 60%

If you have access to a calculator, you could also divide the numerator by the denominator and turn the fraction into a decimal. Decimals are simple to convert into percent notation.

Decimals are even easier to convert into percentages. To convert a decimal into a percentage, multiply the decimal by 100 and add the percent sign. To multiply a decimal by 100, move the decimal point two digits to the right:

0.8= 0.8 x 100 = 80% 0.53: 0.53 x 100 = 53% 0.173: 0.173 x 100 = 17.3%

You can also use this method to convert decimal numbers that are larger than 1. Say you know there are 1.34 times as many books in your library this year than last year, and you want to know what percentage the number of books you have this year is of the books you had last year. As before, you would multiply 1.34 by 100 and add the percent sign:

1.34 x 100 = 134%

Your number exceeds 100 percent because you're comparing this year's book total to the total books from last year, a number represented by 100 percent. Since there are more books this year, that percentage is larger than 100.

You can convert percentages to decimals using the opposite operation. Instead of multiplying the decimal by 100, divide the percent by 100. If 56 percent of people eat roast beef sandwiches you could also say that for every 100 people, 56 eat roast beef. Divide 56 by 100. Because you're dividing by 100, you'll move the decimal point two places to the left:

56/100 = 0.56

Other conversion examples are: 5%: 5/100 = 0.05, 79%: 79/100 = 0.79, 295%: 295/100 = 2.95

The required time taken by the Devin to complete 5.8 laps is 24.36 minutes.

To find out how long it takes Devin to complete 5.8 laps, we need to multiply the time it takes to complete one lap by the number of laps. If it takes Devin 4.2 minutes to walk a lap, then to complete 5.8 laps, it would take.

time = 4.2 minutes/lap * 5.8 laps

= 24.36 minutes.

So, it would take Devin 24.36 minutes to complete 5.8 laps.

This information can be useful for determining Devin's walking pace, comparing his time to that of others, or calculating the total distance he has covered.
