Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Reflection is the flipping of a point about an axis. If a figure with point A(x, y) is reflected about the y axis, the new point is A'(-x, y)
The quadrilateral KLMN has vertices at K(-2, 6), L(-3, 8), M(-4, 4) and N(-3, 2). If the quadrilateral is reflected about the y axis, the new point is at:
K(2, 6), L(3, 8), M(4, 4) and N(3, 2)
The figure was plotted using geogebra online graphing tool.
What is the probability that the daughter of an unaffected father and a mother who is a carrier for the dmd allele will have dmd?
The probability that a daughter of an unaffected father and a mother who carries the dmd allele will develop the disease is 50 percent.
One from each parent, a girl receives the two X chromosomes. The daughters therefore have a 50% chance of acquiring the mutation and developing into carriers. Sons without DMD won't be carriers, but daughters without the condition will.
Carriers will always run the risk of giving birth to a child who carries the mutation or the disease, even if they don't show any symptoms of it themselves.
What is DMD?
Duchenne muscular dystrophy (DMD) is a genetic disorder characterized by progressive muscle degeneration and weakness caused by changes in a protein called dystrophin, which aids in the maintenance of muscle cells. DMD is one of four types of dystrophinopathies.

Answer:
133°
Step-by-step explanation:
As vertically opposite angles are equal,
< B E D = < F E G
Therefore,
< B E D = 47°
We know that co - interior angles which occur between 2 parallel lines, are added up to 180°.
Given that, < A B E = x
Therefore,
< B E D + < A B E = 180 °
47 + x = 180
x = 180 - 47

3. The population of bees has been increasing by 5% each year since 2010. There were 1,000 bees counted in 2010. a. Create an explicit formula that models the bee population for n years since 2010. (Hint: What function have we studied that can be represented by this situation?)
Answer: 1000 x 1.05^n
Step-by-step explanation:
1.05 is the increase experienced each year and n is the number of years.
Answer:
The population of bees is increasing by 5% each year since 2010. Let P(n) be the population of bees in the nth year since 2010.
The explicit formula for the bee population can be found using the formula for compound interest:
P(n) = P(0) * (1 + r)^n
where P(0) is the initial population in 2010, r is the annual growth rate, and n is the number of years since 2010.
Substituting the given values, we have:
P(n) = 1000 * (1 + 0.05)^n
Simplifying the expression, we get:
P(n) = 1000 * 1.05^n
Therefore, the explicit formula that models the bee population for n years since 2010 is P(n) = 1000 * 1.05^n.
One last question the floor of Raj’s classroom has an area of 525 feet.The ceiling is 12 feet high.What is the volume of Raj’s classroom?
Answer:
6300 ft
Step-by-step explanation:
Answer:
The volume of Raj's classroom would be 6,300 cubic feet which is the multiplication of the floor area and the height of the room.
What is the volume of the cuboid?
The volume of a cuboid is equal to the product of the length, width, and height of a cuboid.
The volume of a cuboid is length × breadth× height
Raj's classroom floor area measures 525 square feet. The ceiling height of the room is 12 feet.
The volume of Raj's classroom is the multiplication of the floor area and the height of the room.
The volume of Raj's classroom = the floor area × the height of the room
The volume of Raj's classroom = 525 × 12
The volume of Raj's classroom = 6,300 cubic feets
Thus, the volume of Raj's classroom would be 6,300 cubic feet.

Cual es el area de un semicírculo que se diámetro es 14
The area of a circle is given by:
\(A_C=\frac{1}{4}\cdot\pi\cdot d^2.\)Where π ≅ 3.14 and d is the diameter of the circle.
Now, a semi-circle is a half of a circle, so its area is half of the area of the complete circle:
\(A_{SC}=\frac{1}{2}\cdot A_C=\frac{1}{2}\cdot(\frac{1}{4}\cdot\pi\cdot d^2)=\frac{1}{8}\cdot\pi\cdot d^2\text{.}\)Replacing the value d = 14 in the last formula, we get:
\(A_{SC}=\frac{1}{8}\cdot\pi\cdot(14units)^2=24.5\cdot\pi\cdot units^2\cong76.97units^2.\)Answer
The area of a semicircle with a diameter d =14 is approximately 76.97 units square.
what is the area principle? the area principle says that when images are used to compare amounts, the areas of the images should be proportional to the amounts. the images should be different for each amount. the area of the background should be clean and white, with no distractions. the images should be polygons, making it easier to assess the area.
The area principle is a fundamental concept in data visualization that states that the size of a graphical element (such as a bar, a pie slice, or a bubble) should be proportional to the quantity it represents.
In other words, the area of the graphical element should accurately reflect the magnitude of the data it is displaying. This principle is particularly important when comparing quantities, as it allows the viewer to quickly and accurately perceive the relative differences between them. For example, if two bars in a bar chart have the same width but different heights, the viewer may be misled into thinking that the two quantities are closer in magnitude than they actually are.
The area principle is often applied in conjunction with other principles of good data visualization, such as using clear and simple designs, avoiding clutter, and choosing appropriate scales and units. The goal is to create visualizations that are not only aesthetically pleasing but also informative and effective in communicating the underlying data.

At the beginning of a month, a factory has enough materials to make 240 tonnes of steel in a month. If 60 more tones of steel are to be made in that month, how long will
the materials last?
Answer:
The material will be used for 24 days.
Step-by-step explanation:
Given that:
Materials made in a month = 240 tonnes
More materials to be made = 60 tonnes
Total material to be made = 240+60 = 300 tonnes
Days in a month = 30 days
Materials : Days
240 : 30
300 : x
As the production is increasing, the material will be used before 30 days.
This is an inverse proportion.
\(\frac{240}{300}=\frac{x}{30}\)
Using cross multiplication;
300*x = 240*30
300x = 7200
Dividing both sides by 300
\(\frac{300x}{300}=\frac{7200}{300}\\x=24\)
Hence,
The material will be used for 24 days.
there are 21 roots of the function f(x) = cos x on the interval [0, 65]. to which root will the bisection method converge, starting with a = 0 and b = 65?
The bisection method will converge to a root of f(x) = cos(x) on the interval [0, 65].
The bisection method is a numerical algorithm that finds a root of a function f(x) within a given interval [a, b] by repeatedly dividing the interval in half and determining which half contains a root. The method converges to a root if the function is continuous and changes sign across the interval [a, b].
In this case, the function f(x) = cos(x) is continuous on the interval [0, 65], and it changes sign multiple times, indicating the presence of multiple roots. Specifically,
f(0) = 1f(π/2) = 0f(π) = -1f(3π/2) = 0so there are roots at x = π/2 and x = 3π/2, as well as additional roots between 0 and π/2, and between π/2 and 3π/2.
Since there are 21 roots of the function on the interval [0, 65], it is not possible to determine which root the bisection method will converge to without further information about the behavior of the function within the interval.

Given f(x)=x*-x³-6x², for what values of x will f(x) > 0?
The values of x will f(x) > 0 for x < 0, and f(x) < 0 for -6 < x < 0 and x > -6.
To determine the values of x for which f(x) > 0, we need to find the intervals where the function is positive. Let's analyze the function f(x) = x*-x³-6x².
First, let's factor out an x from the expression to simplify it: f(x) = x(-x² - 6x).
Now, we can observe that if x = 0, the entire expression becomes 0, so f(x) = 0.
Next, we analyze the signs of the factors:
1. For x < 0, both x and (-x² - 6x) are negative, resulting in a positive product. Hence, f(x) > 0 in this range.
2. For -6 < x < 0, x is negative, but (-x² - 6x) is positive, resulting in a negative product. Therefore, f(x) < 0 in this range.
3. For x > -6, both x and (-x² - 6x) are positive, resulting in a negative product. Thus, f(x) < 0 in this range.

ap calculus chapter 6 worksheet applications of integration review sheet a let r and s be the regions in the first quadfrant bounded by the graphs
The regions R and S in the first quadrant are bounded by specific graphs, and the task is to find the areas of these regions.
To determine the areas of regions R and S, we need to analyze the given graphs and apply integration techniques. Region R is bounded by the x-axis, the graph of y = f(x), and the vertical line x = a. To find the area of this region, we can integrate the function f(x) from x = 0 to x = a. The integral ∫[0,a] f(x) dx will yield the area of region R.
Region S, on the other hand, is bounded by the graph of y = g(x), the line x = a, and the line y = b. To find the area of this region, we first need to identify the points of intersection between the graphs. These points will help us determine the limits of integration. Once we have the appropriate limits, we can integrate the function g(x) from x = a to x = c, where c is the x-coordinate of the intersection point between the graphs of g(x) and y = b. The resulting integral ∫[a,c] g(x) dx will provide us with the area of region S.

A group of friends wants to go to the amusement park. They have $416. 75 to spend on parking and admission. Parking is $15. 25, and tickets cost $36. 50 per person, including tax. Which equation could be used to determine
�
x, the number of people who can go to the amusement park?
The equation 36.50x + 15.25 = 416.75 can be simplified to solve for x, representing the number of people who can go to the amusement park. By isolating the variable, we find that x is approximately 11, meaning that 11 people can go to the amusement park with the given budget.
The term x(36.50) represents the total cost of admission tickets for x number of people, and 15.25 represents the cost of parking. The sum of these costs must be equal to the total amount of money available, which is $416.75. To solve for x, we can first simplify the equation to 36.50x + 15.25 = 416.75, and then isolate the variable by subtracting 15.25 from both sides, giving 36.50x = 401.50. Finally, we can divide both sides by 36.50 to find that x is approximately 11, meaning that 11 people can go to the amusement park with the given budget.

Thomas' Bike Shop stocks a high volume item that has a normally distributed demand during lead time. The average daily demand is 70 units, the lead time is 4 days, and the standard deviation of demand during lead time is 15.
1) How much safety stock provides a 95% service level to Thomas?
2) What should the reorder point be
The required answer is set the reorder point at approximately 304.68 units.
Explanation:-
1) To calculate the safety stock for a 95% service level, we need to find the appropriate z-value for the normal distribution. A 95% service level corresponds to a z-value of 1.645.
Safety Stock = z-value * Standard Deviation of Demand during Lead Time
Safety Stock = 1.645 * 15
Safety Stock ≈ 24.68 units
So, Thomas needs to maintain approximately 24.68 units of safety stock to provide a 95% service level.
2) To calculate the reorder point, we need to consider the average demand during lead time and the safety stock.
Reorder Point = (Average Daily Demand * Lead Time) + Safety Stock
Reorder Point = (70 units/day * 4 days) + 24.68 units
Reorder Point ≈ 280 + 24.68
Reorder Point ≈ 304.68 units
Thomas should set the reorder point at approximately 304.68 units.
