The coordinates of the square are 2.8

A square is a polygon whose all sides are equal.  the if the sides are equal, the coordinates of the vertices are also equal to each other.

The length of the diagonal of the square is gotten by the use of the formula for distance between two points

d = √(y₂-y₁)²+(x₂-x₁)²

distance = √(6-2)²+(-2-2)²

distance = √4²+-4²

Distance = √16+16

distance = √32 = 5.7 units

This implies that the sides of the square = 5.7/2 = 2.8

The maximum score that can be in the bottom 5% of scores is 2.64

The middle 90% of scores lie between 2.88 and 4.56.

(a) To find the maximum score that can be in the bottom 5% of scores, we need to find the score that corresponds to the 5th percentile of the normal distribution.

Using the mean and standard deviation provided (3.6 and 0.75, respectively), we can use the standard normal table to find that the 5th percentile corresponds to a standard normal score of -1.28. To convert this back to the original scale, we can use the formula:

x = mu + z * sigma

Where

Plugging in the values, we get:

x = 3.6 + (-1.28) * 0.75

x= 2.64

(b)

To find the range of scores that the middle 90% of scores lie between, we need to find the 5th and 95th percentiles of the normal distribution.

Using the mean and standard deviation provided (3.6 and 0.75, respectively), we can use the standard normal table to find that the 5th percentile corresponds to a standard normal score of -1.28 and the 95th percentile corresponds to a standard normal score of 1.28. To convert these back to the original scale, we can use the formula:

x = mu + z * sigma

Where

Plugging in the values, we get:

x = 3.6 + (-1.28) * 0.75

= 2.88 for the 5th percentile

x = 3.6 + 1.28 * 0.75

= 4.56 for the 95th percentile

(2, 23) is a solution for the equation y = 9x + 5

Step-by-step explanation:

(2, 23) means that for an x value of 2, the y value should be 23

The equation is y = 9x + 5

Substitute x = 2 on the right side

y = 9(2) + 5 = 18 + 5 = 23

Since this matches the given value of y =23, we can conclude that

Answer:

14 inches is to 56 miles

Step-by-step explanation:

First, let's convert the question into an "equation"

1in : 4mi as xin:56mi

Since we need to multiply 4mi by 14 to 56mi, we will multiply 1in by 14 to find the value of x. 1 * 14 = 14. So, x must be equal to 14 and 1 inch is to 4 miles as 14 inches is to 56 miles.

If this answer helped you, please leave a thanks or a Brainliest!!!

Have a GREAT day!!!

It is given to us in the question that we have a proportion of 1 inch is to 4 miles.

The proportion we need to solve is, 1 : 4 :: x : 56  as given in the question.

To solve this,

If 1 inch is equal to 4 miles, that means 4 miles is equal to 1/4 inch.

i.e. 1x = 4y; where x is inches and y is miles

1y = 1x/4....................(i)

Similarly, from the above-given proportion, we see that

x = 56y;

Taking the value of y from (i),

x = 56 * (1/4)

= 14

So the proportion becomes,

1 inch : 4 miles :: 14 inch : 56 miles

Hence, it can be determined that 1 inch is to 4 miles as 14 inches is to 56 miles.

Answer:

1267 people

Step-by-step explanation:

The area of the 10 feet by 10 feet square is 100 square feet. If 20 people fit comfortably in this area, we can use this information to estimate the number of people in a larger area.

Since we know that 20 people fit in 100 square feet, we can calculate how many people would fit in a larger area by multiplying the number of square feet by 20.

A 1 mile section of a parade route is approximately 5280 feet long and 12 feet deep (on one side of the street). Therefore, the area that the crowd is occupying is approximately 5280*12 = 63,360 square feet.

So, the number of people that would fit in this area would be approximately:

63,360 square feet * 20 people/100 square feet = 1267.2 people.

So we can estimate that 1267 people will comfortably fit in a 1 mile section of a parade route that is 12 feet deep on one side of the street.

The function is being transformed with a dilation of scale factor of 3 and an upward vertical shift of 4.

A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system.

Given is a function under some transformations, 3 h(x) + 4 ;

If we consider h(x) as a parent function, then the result after the transformation is 3h(x)+4,

We see that, it is being multiplied by 3, we know that if a function is being multiplied by a number greater than 1 in transformation then it is dilated by a scale factor of the number, hence, the function is being dilated by a scale factor of 3.

Also, we see, here is an addition of 4, we know that, when function is added by a certain number then in the transformed function the function is shifted vertically and addition mean it shifted vertically upwards, sine, 4 is added to the function it means, the function is shifted 4 unit vertically upwards.

Hence, the function is being transformed with a dilation of scale factor of 3 and an upward vertical shift of 4.

Answer:

The annual percentage yield (APY) is the effective annual rate of return on an investment, taking into account the effects of compounding. To calculate the APY, we can use the formula:

APY = (1 + (APR / n))^n - 1

Where APR is the annual percentage rate (the stated interest rate), and n is the number of times the interest is compounded per year.

In this case, the APR is 4.86% and the interest is compounded daily, so n = 365 (the number of days in a year).

APY = (1 + (0.0486 / 365))^365 - 1

Plugging in the numbers, we get:

APY = (1 + 0.000132876712328767123)^365 - 1

APY ≈ 4.87%

So, the annual percentage yield is 4.87%

The y - intercept of the function f(x) = (3x + 4)⁴(x - 5)⁵ is (0, -800,000)

When an equation's graph crosses the y-axis, that location is known as the y-intercept. When x = 0, it is y's value.

A linear equation's constant term serves as a representation for the y-intercept. The y-intercept of the equation y = 2x + 3 is 3, for instance. This indicates that the coordinate plane point (0, 3) is at y = 3 when x = 0.

y= mx + b, where m is the slope and b is the y-intercept, is another way to express a linear equation.

For instance, the equation y = -2x + 5 can be written as y = -2x + 5, and since the y-intercept is 5, the point (0, 5) is on the graph of the equation.

The y-intercept of an equation, or the value of y when x = 0, is the point at which the graph of the equation crosses the y-axis. It can be represented by b in the slope-intercept form of a linear equation as well as by the constant term in the equation.

In the function given;

f(x) = (3x + 4)⁴(x - 5)⁵

Substitute the value of 0 for x and solve to find the y - intercept.

f(0) = (3(0) + 4)⁴(0 - 5)⁵

f(0) = -800000

The function for this problem is defined as follows:

f(x) = (3x + 4)^4(x - 5)^5

Graphically, the y-intercept of a function represents the value of y assumed by the function when the graph of the function crosses the y-axis.

Hence, algebraically, the y-intercept of a function is given by the numeric value of the function when the input x assumes a value of zero.

The numeric value of the function at x = 0 is calculated replacing the two instances of x in the function by zero, hence the y-intercept of the function is defined as follows:

f(0) = (3(0) + 4)^4(0 - 5)^5

f(0) = 4^4 x (-5)^5

There is an exponent rule which essentially states: [tex]\frac{x^a}{x^b}=x^{a-b}[/tex]

All this is doing is essentially cancelling out the terms, since you can think of it as: [tex]\frac{x^a}{x^b}\implies \frac{x*x*x...\text{ "a" amount of times}}{x*x*x...\text{"b" amount of times}}[/tex], and if you recall, multiplication and division cancel. So we cancel out "b" amount of x's, leaving us with "a - b" amount of x's. Which can also be expressed as: [tex]x^{a-b}[/tex]

We can use this logic to solve our problem: [tex]\frac{20x^6}{14x^2}[/tex], here we can separate this into two different fractions: [tex]\frac{20}{14}*\frac{x^6}{x^2}[/tex] and we can use basic division on the left side and our exponent rule on the right side.

D. 2r2 + 23r > 645

Step-by-step explanation:

The equation "2r^2 + 23r > 645" represents the situation because it states that the number of spaces in the parking lot, represented by the left-hand side of the equation (2r^2 + 23r), is greater than the maximum number of spaces that the parking lot can hold (645). This is consistent with the information given in the problem, which states that the parking lot has been expanded and can now hold more spaces.

The other equations given (A, B, C) do not accurately represent the situation because they do not take into account the expansion of the parking lot and the addition of new rows and spaces.
