Answer:  20.8 cm

Step-by-step explanation:

Notice that the corners of the squares form a line.

Set the x-axis to time and the y-axis to length of a side (not perimeter) to create coordinates.

At 0 seconds the side length is 1 --> (0, 1)

At 2.5 seconds the perimeter is 32 (side length is 32/4 = 8) --> (2.5, 8)

First, find the slope between the coordinates using    \(m=\dfrac{y_2-y_1}{x_2-x_1}\)

Let (x₁, y₁) = (0, 1) and (x₂, y₂) = (2.5, 8)

\(m=\dfrac{8-1}{2.5-0}\quad =\dfrac{7}{2.5}\quad =\dfrac{7}{\frac{5}{2}}\quad =\dfrac{14}{5}\quad =2.8\)

Next, use the Point-Slope formula to find the equation of the line:

\(y-y_1=m(x-x_1)\\\\y-1=2.8(x-0)\\\\y=2.8x+1\)

Lastly, find the side length (y) when x = 1.5

y = 2.8(1.5)x + 1

  = 4.2 + 1

  = 5.2

Perimeter of a square = 4 times the side length

P = 4(5.2)

  = 20.8

The linear equation of the line is y = 34x -  7 and y + 7 = 34(x - 0)

The slope is given as:

m = 34

The y-intercept is given as:

c = -7

A linear equation in slope intercept form is represented as:

y = mx + c

So, we have:

y = 34x -  7

The equation in point slope form is calculated as follows:

y = 34x -  7

Add 7 to both sides

y + 7 = 34x

Express 34x as 34(x)

y + 7 = 34(x)

Subtract 0 from x

y + 7 = 34(x - 0)

Hence, the linear equation of the line is y = 34x -  7 and y + 7 = 34(x - 0)

Using proportions, it is found that your cost is of $12,411.

A proportion is a fraction of a total amount.

In this problem, the treatment costs $16,911, with a deductible of $1,000, hence the price is already of $15,911.

The insurance will pay 85% of the remaining cost, or $3,500, whichever is greater, hence:

0.85 x 15911 = $13,524 > $3,500.

Hence, the insurance pays only $3,500, and your cost is given by:

Answer:

Step-by-step explanation:

I'm going to go way out on a limb here and say that you are probably looking for the equation that goes along with that information. If not, you'll learn something anyway!

The equation that we want to fill in is this one:

\((y-k)^2=4p(x-h)\)

where h and k are the coordinates of the vertex and p is the distance from the vertex to either the focus or the directrix (since the vertex is directly between the 2). If our vertex is at the origin (0, 0) and the focus is at (-2, 0), first and foremost we need to decide what kind of parabola this is. Remember that a parabola wraps itself around the focus. So our parabola opens to the left (that means that in the end, the equation will be negative, but we'll get there in time). Now we need to determine p, since that's the only "mystery" and everything else was given to us.

p = 2. Filling in the equation:

\(-(y-0)^2=4(2)(x-0)\) which simplifies to

\(-y^2=8x\) and now we solve it for x:

\(-\frac{1}{8}y^2=x\)

The weight of the silver in the bar is approximately 6.3 ounces.

Step-by-step explanation:

To find the weight of the silver in the bar, you can multiply the total weight of the bar by the proportion of the bar that is silver. Since the proportion of silver in the bar is 84%, you can express this as a decimal by dividing 84 by 100: 84/100 = 0.84.

Then, you can multiply the total weight of the bar by this decimal to find the weight of the silver:

Weight of silver = total weight of bar * proportion of silver

= 7.5 ounces * 0.84

= 6.3 ounces

Required

Determine the transformation

We have the following observations

Before transformation, the coordinates are: (x,y)

After transformation, the coordinates are: (x,y)

In other words, the coordinates before and after the transformation are the same.

This implies that there is a 360 degrees rotation.

Simply put, when there are no changes in the pre and post transformation of a point, line or shape, then the transformation is 360 degrees

The parallelogram transformed according to the rule (x,y) → (x, y), in other words can be stated as 360 degrees rotation (Ro, 360°).

For 360 degrees rotation, the coordinates before and after the transformation will be the same.

According to this rule, the transformation of (x,y) gives (x, y)

The perimeter of a rectangle has the general formula P=2L+2W. Since you know P and L, you can plug those values into the formula and solve for W.

Hope this answer is right!!

Answer:

Width: 13

Area: 42

Step-by-step explanation:

A rectangle has equal opposite sides, so if you know one side, you know that the opposite side will be the same. Then you can subtract it from the perimeter, and divide the remaining number in half because it represents the other opposite sides. If you were trying to find the area, do that to find the length and width. 29x13=42, so the area is 42. If you were trying to find the width, that would be 13 because

29+29=58

I'm going to assume you need this inequality solved.

First, write it as numbers, not words.

7/10n + 14 < 49

where "n" is the unknown number.

Second, if I were you, I'd change that fraction into a decimal, as it'll make life easier later on.

7/10 = 0.7

Now, solve it like you would any other equation.

0.7n + 14 < 49

0.7n +14 - 14 < 49 - 14

0.7n < 35

0.7n ÷ 0.7 < 35 ÷ 0.7

n < 50

The answer is n < 50

Answer: 50

Step-by-step explanation:

49 - 14 = 35

35/7 = 5

10 x 5 = 50

Since, 35 is Seven tenths of a number, One tenth is 5 and there are ten tenths, One tenth which is 5 times ten since there are ten tenths equals to 50 (5 x 10 = 50).

The equation representing a line that is perpendicular to y=2/3x−5 and passes through the point (6,12) is y = -3x/2 +24

The total number of possible license plates is 45,697,600

There are 5 choices for the first digit (1, 3, 5, 7, 9), 5 choices for the second digit (excluding the one used for the first digit), and 26 choices for each of the following 4 characters. Therefore, the total number of possible license plates is:

5 x 5 x 26 x 26 x 26 x 26 = 45,697,600

Since the license plate must consist of 6 characters, with the first and second digits being odd, there are only 5 choices for each of the first two digits (1, 3, 5, 7, 9). Repetition is not permitted, so once a digit is chosen, it cannot be chosen again.

For the remaining 4 characters, there are 26 choices for each character (A to Z). Therefore, the total number of possible license plates is obtained by multiplying the number of choices for each character, which gives the result of 45,697,600.

There are 1,207,084,032,000 ways for 6 CE majors and 10 CS majors to stand next to each other in the lines.

We use permutations and combinations for solving this problem. We fix the position of CS students so that they can stand in a fixed place by

= 10! ways (i)

Now, there are 11 places left for CE students so that no two CE students stand next to each other.

6 CE students in the rest of the 11 places can sit by = 11! / (11-6)! ways (ii)

Hence, using the values of (i) and (ii), we get -

= (10! * 11!) / (11-6)!

A population of size 1,000 has a proportion of 0.5. Therefore, the proportion and the standard deviation of the sample proportion for samples of size 100 are 0.5 and 0.05, respectively. The correct answer is option D.

When sampling from a population, the sample proportion is expected to be the same as the population proportion. In this case, the population proportion is given as 0.5, so the sample proportion for samples of size 100 is also 0.5.

The standard deviation of the sample proportion can be calculated using the formula sqrt((p * (1 - p)) / n), where p is the population proportion and n is the sample size. Plugging in the values, we get sqrt((0.5 * (1 - 0.5)) / 100) = sqrt(0.25 / 100) = 0.05.

Therefore, the correct answer is option D) 0.5 and 0.050. The sample proportion for samples of size 100 is 0.5, and the standard deviation of the sample proportion is 0.050.

In the context of property variance, a variance refers to a legal authorization or exception granted to a property owner by the local governing authority. It allows the property owner to deviate from specific zoning regulations or land-use restrictions that would otherwise apply to their property.

The variance process is used when property owners believe that strict adherence to the existing regulations would cause undue hardship or prevent them from fully utilizing their property in a way that is reasonable and consistent with neighboring properties.

The purpose of property variances is to address unique circumstances or hardships that may exist for a particular property. Property variances typically involve submitting an application to the local zoning board or planning department, attending public hearings, and providing evidence or arguments to support the need for the variance.

The governing authority evaluates the application based on factors such as the impact on neighboring properties, public health and safety, and the intent of the zoning regulations. If approved, the property owner is granted permission to proceed with the proposed deviation from the regulations.

Overall, property variances provide flexibility in land-use regulations, allowing property owners to find reasonable solutions that meet their specific needs while still considering the broader community interests and objectives of zoning regulations.

The magnitude of the resultant vector is 96.77 and its direction is -78.95°.

To find the magnitude and direction of the resultant vector, we can use vector addition. We can break down each vector into its horizontal and vertical components using trigonometry:

For the first vector with magnitude 35 and direction 55°:

Horizontal component = 35 cos(55°) = 19.77

Vertical component = 35 sin(55°) = 28.25

For the second vector with magnitude 80 and direction 130°:

Horizontal component = 80 cos(130°) = -39.06

Vertical component = 80 sin(130°) = 66.68

To find the horizontal and vertical components of the resultant vector, we can add the corresponding components of the two vectors:

Horizontal component of the resultant vector = 19.77 - 39.06 = -19.29

Vertical component of the resultant vector = 28.25 + 66.68 = 94.93

The magnitude of the resultant vector is the square root of the sum of the squares of its horizontal and vertical components:

Magnitude of the resultant vector = sqrt((-19.29)^2 + (94.93)^2) = 96.77

The direction of the resultant vector can be found using trigonometry:

Direction of the resultant vector = arctan(94.93/-19.29) = -78.95° (measured counterclockwise from the positive x-axis)

Therefore, the magnitude of the resultant vector is 96.77 and its direction is -78.95°.

The distribution of X follows the characteristics of a normal distribution with a mean of 106 and a standard deviation of 18, reflecting the IQ distribution of the ruling species on the faraway planet. This can be denoted as X ~ N(106, 18), where "N" represents the normal distribution.

The distribution of X, representing the IQ of an individual from the ruling species on the faraway planet, is a normal distribution with a mean (μ) of 106 and a standard deviation (σ) of 18. This can be denoted as X ~ N(106, 18), where "N" represents the normal distribution.

In this distribution, the majority of IQ values will cluster around the mean of 106. The standard deviation of 18 indicates the average amount of variation or dispersion from the mean. The normal distribution is symmetric, which means that the probabilities of IQ values being above or below the mean are equal.

The shape of the normal distribution is bell-shaped, with the highest point being at the mean. As we move away from the mean, the probability of observing extreme values decreases. The spread of the distribution is determined by the standard deviation, where a larger standard deviation indicates a wider spread of IQ values.

The smallest angle measures 15 degrees and the other non-right angle measures 75 degrees.

To find the measure of both angles in a right triangle with the given conditions, we will use the information provided:

Let x be the measure of the smallest angle. The problem states that the measure of one of the small angles is 30 less than 7 times the smallest angle, which can be written as:

Other non-right angle = 7x - 30

Since this is a right triangle, the sum of the two small angles must be 90 degrees (because the other angle is 90 degrees, and the sum of angles in a triangle is 180 degrees). So, we can set up the following equation:

x + (7x - 30) = 90

Now, solve for x:

8x - 30 = 90
8x = 120
x = 15

So, the smallest angle is 15 degrees. Now, we can find the measure of the other non-right angle:

Other non-right angle = 7x - 30 = 7(15) - 30 = 105 - 30 = 75 degrees

In summary, the smallest angle measures 15 degrees and the other non-right angle measures 75 degrees.

The limit of (2x-1)(3-x)/(x-1)(x+3) as x approaches infinity is 0.

To find the limit of the function (2x-1)(3-x)/(x-1)(x+3) as x approaches infinity, we will divide both the numerator and denominator through the highest power of x. In this case, the highest power of x is x², so we can divide both the numerator & the denominator through x²:
