1. What are the dimensions of the rectangle with an area of 175 square meters?
2. What is the fixed perimeter for the rectangles represented by the graph? Explain how you found the perimeter.
Answer:
1. width = 35 m, length = 5 m
2. 80 m
Step-by-step explanation:
Question 1From inspection of the given graph, when y = 175, x = 5.
Therefore, when the area of a rectangle is 175 m², its length is 5 m.
The equation for the area of a rectangle is:
[tex]\boxed{\sf Area=width \times length}[/tex]
Therefore, to find the width of the rectangle, input the area of 175 m² and length of 5 m into the equation and solve for width:
[tex]\begin{aligned}\sf Area&= \sf width \times length\\\implies 175&=\textsf{width} \times 5\\\sf width&=\dfrac{175}{5}\\\sf width&=35\; \sf m\end{aligned}[/tex]
Therefore, the dimensions of the rectangle with an area of 175 m² are:
width = 35 mlength = 5 mQuestion 2The equation for the perimeter of a rectangle is:
[tex]\boxed{\sf Perimeter=2(width +length)}[/tex]
Given the width is 35 m and the length is 5 m:
[tex]\begin{aligned}\implies \sf Perimeter=&2(35+5)\\&=2(40)\\&=80\; \sf m\end{aligned}[/tex]

To print out all elements of a two-dimensional array you would normally use a(n) for loop.
What is an array?A collection of elements with the same data type that are stored in sequential memory regions is known as an array. As a result, it is easier to determine each element's position by simply adding an offset to a base value, which is the address in memory where the array's first element is stored (generally denoted by the name of the array).
By defining iteration in a control flow statement, a for loop enables code to be run repeatedly.
A for loop's body, which is executed once for each iteration, and its header both specify the iteration.
Two for loops can be used to print the elements of a two-dimensional array.
Therefore, for loop is used for two dimensional array printing.

LetXbe an affine variety. Show that the coordinate ringA(X)is a field if and only ifXis a single point. In the rest of this chapter we want to study the basic properties of the operationsV(⋅)andI(⋅).
In summary, the statement states that the coordinate ring of an affine variety is a field if and only if the variety is reduced to a single point, making it a well-defined, irreducible, and non-redundant set.
What is coordinate?Coordinates are a pair of integers that are used to locate a point or object in a two-dimensional plane. A point's location on a 2D plane is defined by two integers called the x-coordinate and the y-coordinate. The distance between two points is known as the x-coordinate, or abscissa, while the distance between two points is known as the y-coordinate, or ordinate. Point (3, 2), for example, is three units distant from the positive y-axis and two units away from the positive x-axis.
Here,
In algebraic geometry, the coordinate ring of an affine variety X, denoted by A(X), is a ring that encodes the algebraic information of the variety X. The ring A(X) is defined as the set of polynomial functions on X, with pointwise addition and pointwise multiplication.
The statement "The coordinate ring A(X) is a field if and only if X is a single point" says that the coordinate ring is a field only when the affine variety X is reduced to a single point.
This means that the only non-zero polynomial function on X is the constant function equal to one. In other words, if X is a single point, then any non-zero polynomial on X will have an inverse, making the coordinate ring a field.

How to determine the tangent linesFunction (1)
From the question, we have the following parameters that can be used in our computation:
y = 4x+ 3 and y = 6x - 5
At x = 2, we have
y = 4(2) + 3 and y = 6(2) - 5
So, we have
y = 11 and y = 7
So, we have:
Tangent line: y = 11 * 7
y = 77
Function 2
Here, we have
The derivative of the quotient of two functions:
(d/dx)(f(x)/g(x)) = (g(x) * df/dx - f(x) * dg/dx) / g(x)^2
Substituting the tangent lines for f and g, we get:
(d/dx)(f(x)/g(x)) = (6x - 5 * 4 - (4x + 3) * 6) / (6x - 5)^2
Evaluating at x = 2, we get:
(d/dx)(f(x)/g(x)) = (-16 - 18) / (-3)^2 = -74/49
Hence, the line tangent to the graph of y = f(x)/g(x) at x = 2 is y = -74/49(x - 2) + [f(2)/g(2)].

The wholesaler is willing to supply 68 if the price is $300 and 148 if the price is $390. Assuming the resulting supply and demand functions are linear, find the equilibrium point for the market.
The equilibrium point for the market is (102.54, 351.81).
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
Given that, a group of retailers will buy 104 televisions from a wholesaler if the price is $350 and 144 if the price is $300.
Here, (104, 350) and (144, 300)
Now, slope (m)=(300-350)/(144-104)
= -50/40
= -1.25
Substitute m=-1.25 and (x, y)=(104, 350) in y=mx+c, we get
350=-1.25(104)+c
350=-130+c
c=480
Substitute m=-1.25 and c=480 in y=mx+c, we get
y= -1.25x+480
The wholesaler is willing to supply 68 if the price is $300 and 148 if the price is $390.
The coordinate points are (68, 300) and (148, 390)
Slope (m)= (390-300)/(148-68)
= 90/60
= 3/2
= 1.5
Substitute m=1.5 and (x, y)=(68, 300) in y=mx+c, we get
300=1.5×68+c
c=198
Substitute m=1.5 and c=198 in y=mx+c, we get
y=1.5x+198

Answer:
P = C(55,845, 40) / C(56,142, 40) = (55,845!) / (40! * (55,845 - 40)!) / (56,142!) / (40! * (56,142 - 40)!)
Step-by-step explanation:
To find the probability that none of the 40 subjects randomly selected left the treatment center against medical advice, we can use the formula for combinations. The number of ways to choose 40 subjects out of 55,845 that did not leave against medical advice is given by C(55,845, 40), which can be calculated as:
C(55,845, 40) = 55,845 choose 40 = (55,845!) / (40! * (55,845 - 40)!)
The probability that none of the 40 subjects randomly selected left the treatment center against medical advice is given by the number of ways to choose 40 subjects out of 55,845 that did not leave against medical advice, divided by the number of ways to choose 40 subjects out of 56,142 total subjects:
P = C(55,845, 40) / C(56,142, 40) = (55,845!) / (40! * (55,845 - 40)!) / (56,142!) / (40! * (56,142 - 40)!)
National results for the SAT test show that for college-bound seniors, the average combined SAT writing, math, and verbal score is 1500. The standard deviation is 250. National results for the ACT test show that for college-bound seniors, the average composite ACT score is 21 and the standard deviation is 5. Both the ACT and SAT are normally distributed so the Empirical Rule can be applied to their distributions. What percentage of seniors will score a 31 or higher on the ACT?
16 percentage of seniors will score a 31 or higher on the ACT. This can be solved using the concept of standard deviation.
What is Z-score?The Z-score provides information on how much a given value deviates from the standard deviation. The amount of standard deviations a given data point is above or below the mean is represented by the Z-score, also known as the standard score. Essentially, standard deviation is a measure of the degree of variability within a given data collection.
Given that,
SAT score is normally distributed with a mean score of μ = 1500 and the standard deviation of σ = 250,
The ACT score is also normally distributed with a mean score of μ = 21 and the standard deviation of σ = 5,
To calculate the percentage of scores above x = 21 is calculated by finding the Z score which is calculated as:
Z = (x - μ) / σ
Z = 31 - 21 / 5 = 2
now since 68% of scores is between 1 standard deviation and the shape is symmetric hence (100-68)/2 = 16% of values will be above 1 standard deviation.
Thus 16% of scores will be have score higher than 31.

the area of a square with coordinates at: (–5, 3), (1, 1), (–5, –1), and (–1,3)
Therefore, the area of the square with coordinates at (–5, 3), (1, 1), (–5, –1), and (–1,3) is 40 square units.
How do you use coordinates?A coordinate is indeed a geometry technique that uses one or more quantities or coordinates to better be able to watch points as well as other geometrical items on a continuum, such as Ellipsoid. A point or object's coordinates on the double plane are indeed a combination of integers. The y and x dimensions of a point on a plane surface are two numbers that identify its location. a collection of numbers that represent exact coordinates.
Here,
To find the area of a square with these coordinates, we need to find the length of one of its sides first. We can use the distance formula to find the length of the side between two adjacent vertices:
Side AB: √((1-(-5))² + (1-3)²) = √(36 + 4) = √(40) = 2√(10)
Side BC: √((-5-1)² + (-1-1)²) = √(36 + 4) = √(40) = 2√(10)
Since the opposite sides of a square are equal, we know that the other two sides also have a length of 2sqrt(10).
Now we can use the formula for the area of a square, which is side squared. In this case, the area is:
Area = (2√(10))² = 4 × 10 = 40
Therefore, the area of the square with coordinates at (–5, 3), (1, 1), (–5, –1), and (–1,3) is 40 square units.

The specified interior angle of the triangle ΔOBJ, ∠J = 47°
The segments OJ and BO are radial lengths of the circle, therefore;
JO ≅ BO
JO = BO (definition of congruency)
The triangle ΔOBJ is an isosceles triangle (definition of isosceles triangles)
∠J ≅ ∠B (Base angles of an isosceles triangle)
∠B = ∠J = 47°
m∠BOJ = 180°- 47° - 47° = 86° (angle sum property of a triangle)
Whereby EJ is a diameter of the circle, with center at O, we get;
∠BOJ and ∠BOE are linear pair angles, therefore;
m∠BOJ + m∠BOE = 180° (Linear pair angles are supplementary)
m∠BOE = 180° - m∠BOJ
m∠BOE = 180° - 86° = 94°
The exterior angle theorem indicates that we get;
m∠BDE = Half the difference of the intercepted arcs BJE and BE, found as follows;
[tex]m\widehat{BE}[/tex] = m∠BOE = 94°

When will the two hikers be at the same elevation?
Answer:
Time taken for both hikers to be at the same elevation = 14 minutes
At that time, they will both be at an elevation of 270 feet
Step-by-step explanation:
Let us represent Jenny's current elevation by x and Julian's current elevation by y
Let T be the time taken when the hikers reach the same elevation
For Jenny
Initially Jenny's elevation is at 480 feetHer rate of descent (vertically) is 15 feet per minuteSo in T minutes she would have descended 15T feet. Jenny's elevation after T minutes = 480 - 15T feetFor Julian
Initial elevation = 200 feetRate of vertical ascent = 5 feet /minuteAfter T minutes, vertical ascent = 5T minutesHis elevation would be : 200 + 5TSince at this point in time, the elevation of both hikers is equal,Check working
After 14 minutes, Jenny's elevation = 480 - 15 x 14 = 480 = 210 = 270 feet

a square is inscribed in a circle with a radius of "72".If a point in the circle is chosen at random, what is the probability that the point is outside the square?
round your answer to the nearest tenth of a percent
Answer:
36.3%
Step-by-step explanation:
If a square is inscribed in a circle, the diagonals of the square must pass through the center of the circle and be equal to the diameter
Radius of circle = 72
Diameter of circle = 72 x 2 = 144
Therefore the diagonal of the square:
d = 144
If the side of a square is a, the diagonal is given by the formula
d = a√2
Plugging in the known value of d = 144 we get
a√2 = 144
a = 144/√2
Area of the square = a² = (144/√2)² = 144²/2 = 10,368
Area of the circle = πr² = (72)² x π = 16,286 rounded to nearest integer
Area of region outside the square = 16,286 - 10, 368 = 5,918
P(point outside square) = Area of region outside square/area of circle
= 5,918/16,286
= 0.3634
= 36.34 %
= 36.3 % rounded to the nearest tenth
The point where the horizontal axis and the vertical axis intersect in a coordinate plane is called the
The point where the horizontal axis and the vertical axis intersect in a coordinate plane is called the ORIGIN.
Given the question below:
What is the intersection of the vertical and horizontal lines in a coordinate plane?
A coordinate plane is a plane formed by a horizontal number line (the x-axis) and a vertical number line (the y-axis) that intersect at a point called the origin.
The vertical intercept (y-intercept) is found by evaluating the function when the input variable, x, is 0 and is always the same as the constant b. It can be thought of as the original value of the function. The horizontal intercept (x-intercept) is the value of the variable x when the function value is 0.

Michelle reads a book for the school Read-A-Thon. The table shows the proportional relationship between x, the number of minutes and y, the total number of pages read.
a. Determine the rates of change and explain its meaning in the context of this situation.
b. Write an equation to represent the total number of pages as it relates to the number of minutes read.
Answer: a. The rate of change in this situation represents the average number of pages read per minute. From the table, it can be seen that the rate of change is constant, as the ratio of the change in y (pages) to the change in x (minutes) is always the same.
For example, when x increases from 0 to 5, y increases from 0 to 25, so the rate of change is 25/5 = 5 pages per minute.
b. To represent the total number of pages as it relates to the number of minutes read, a linear equation can be used. The slope of the line represents the rate of change, and the y-intercept represents the number of pages read when x is equal to 0 (minutes).
Using the rate of change from the above example (5 pages per minute), the equation can be written as y = 5x + 0, where x represents the number of minutes and y represents the total number of pages read.

for each situation, described given a linear model, is there a correlation. if so is there a causal correctaion
The given linear model and the correlation are true. The particular circumstance will, however, determine if there is a causal association between the two variables.
Yes, there is a correlation between the two variables in the supplied linear model, proving that there is a connection between them. This correlation, which is vital for assessing the strength of their link, is graphically displayed using the linear model. However, since this correlation is not always present, whether there is a causal association between the two variables depends on the particular circumstance. For instance, two variables could have a high correlation, but neither one of them necessarily causes the other. More investigation into the cause-and-effect relationship between the two variables is required to ascertain whether there is a causal correlation.
