The rule (x,y)→(2x,2y) maps △DEF to △D′E′F′. Which statement correctly describes the relationship between △DEF and △D′E′F′ ?
A. The triangles are congruent because △D′E′F′ is a rotation of △DEF , and a rotation is a rigid motion.
B. The triangles are not congruent because △D′E′F′ is a dilation of △DEF , and a dilation is not a rigid motion.
C. The triangles are not congruent because △D′E′F′ is a translation of △DEF , and a translation is not a rigid motion.
D. The triangles are congruent because △D′E′F′ is a reflection of △DEF , and a reflection is a rigid motion.
Answer: B. The triangles are not congruent because △D′E′F′ is a dilation of △DEF , and a dilation is not a rigid motion.
Step-by-step explanation:
Given : The rule (x,y)→(2x,2y) maps △DEF to △D′E′F′.
We can see that a scale factor (2) is used in the above rule.
Rigid motions do not use any scale factor.
The transformation that uses scale factor to transforms figure is dilation.
And Dilation is not rigid motion because it does not produce congruent images.
Hence, The triangles are not congruent because △D′E′F′ is a dilation of △DEF , and a dilation is not a rigid motion.
Finding slope from an equation
Answer:
[tex]\frac 15[/tex]
Step-by-step explanation:
Hello!
We can convert it into slope intercept form: [tex]y = mx + b[/tex]
m = slopeb = y-interceptConvert:[tex]-15 - x = -5y[/tex][tex](-15 - x)\div(-5) = y[/tex][tex]3 + \frac15x = y[/tex][tex]y = \frac15x + 3[/tex]The slope is [tex]\frac15[/tex].
Finding the slope of a line from its equation depends on the equation's form. If it's already in slope-intercept form (y = mx + b), the coefficient of x (m) is the slope. If not, rewrite it to that form by isolating y. Alternatively, use the point-slope form (y - y1 = m(x - x1)) with a known point on the line and solve for m. Remember, the slope tells you how much the line rises/falls per unit move to the right. For the equation in the image, the slope is 1/5.
• Using the slope-intercept form: This is the most straightforward way to find the slope if the equation is already in slope-intercept form, which is y = mx + b. In this form, the slope (m) is the coefficient of the x term. For example, if the equation is y = 2x + 3, the slope is 2.
• Using the standard form: If the equation is not in slope-intercept form, you can first rewrite it in slope-intercept form. To do this, you need to isolate the y term. For example, if the equation is 3x + 2y = 6, you would first subtract 3x from both sides to get 2y = -3x + 6. Then, you would divide both sides by 2 to get y = -3/2x + 3. Once the equation is in slope-intercept form, you can find the slope as described in the first method.
• Using the point-slope form: The point-slope form of the equation of a line is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope. To find the slope using this form, you need to plug in the coordinates of a point on the line. For example, if the equation is y - 2 = 3(x - 1), and you know that the point (3, 7) is on the line, you can plug in x = 3 and y = 7 to get 5 = 3(2). Solving for m, you get m = 5/3.
The slope of a line tells you rise over run, or how much the line goes up or down for every unit it goes to the right. A positive slope means the line goes up as you move to the right, a negative slope means the line goes down as you move to the right, and a zero slope means the line is horizontal.
In the image, the equation is -15 - x = -5y. To find the slope using the slope-intercept form, we need to rewrite the equation so that y is isolated on one side. We can do this by adding x and dividing both sides by -5:
y = (1/5)x + 3
Therefore, the slope of the line is 1/5.

A bag contains 144 ping-pong balls. more than half of the balls are painted orange and the rest are painted blue. two balls are drawn at random without replacement. the probability of drawing two balls of the same color is the same as the probability of drawing two balls of different colors. how many orange balls are in the bag?
There are approximately 72 orange balls in the bag.
We have,
Let's assume the number of orange balls in the bag is x.
Given that more than half of the balls are painted orange, we have the inequality:
x > 144/2
x > 72
Now, let's consider the probability of drawing two balls of the same color:
The probability of drawing two orange balls.
= (x/144) * ((x-1)/(144-1))
= (x(x-1))/(144*143)
The probability of drawing two blue balls.
= ((144-x)/144) * ((144-x-1)/(144-1))
= ((144-x)(143-x))/(144*143)
Given that the probability of drawing two balls of the same color is the same as the probability of drawing two balls of different colors, we can set up the equation:
(x(x-1))/(144143) = ((144-x)(143-x))/(144143)
Simplifying the equation:
x(x-1) = (144-x)(143-x)
x^2 - x = 144143 - 287x + x^2
288x = 144143
x = (144*143)/288
x ≈ 72

The top and bottom margins of a poster are 4 cm and the side margins are each 8 cm. if the area of printed material on the poster is fixed at 388 square centimeters, find the dimensions of the poster with the smallest area.
To find the smallest poster area with a fixed printed area of 388 square centimeters, calculate optimized values for the width and height of the printed area, considering the margins, and derive the poster's dimensions by adding the margins to these values.
Explanation:To find the dimensions of the poster with the smallest area given a fixed printed area, we should first determine the dimensions of the printed area. We know that the printed area is 388 square centimeters and that the margins do not change. Let's denote the width of the printed area as w and the height as h.
The area of the printed material is given by Area = w × h = 388 cm². The total width of the poster would be w + 2×(8 cm) (since there are two side margins), and the total height would be h + 2×(4 cm) (since there are top and bottom margins).
To minimize the area of the poster, we need to minimize the function for the total area of the poster A(w,h) = (w + 16)(h + 8). As the printed area is fixed, we can express h in terms of w using h = 388/w and substitute this into the function to get A(w) = (w + 16)((388/w) + 8).
Taking the derivative dA/dw and setting it to zero, we find the optimal value for w, and consequently, we calculate h. The dimensions of the poster that minimize the total area can then be determined by adding the margins to these optimized values of w and h.

Answer:
Area and Side length of a rhombus.
Step-by-step explanation:
1. Area and side length of a rhombus - This is least proportional as they are inversely proportional.
2. Distance and time when speed is constant is proportional.
Distance = speed x time
When speed is constant, the distance increases with respect to speed.

As the number of tickets purchased increases, the cost also increases.
4. Hours worked and money earned
When the number of hours increases, the money earned also increases.
the length of a rectangle is 5cm less than 3 times the width.if the perimeter of a rectangle is 54cm, find the length and the width
To solve for the length and width of the rectangle, equations were set up based on the given perimeter and the relation between length and width. The width was found to be 8 cm, and substituting this into the length formula gave a length of 19 cm.
The question concerns finding the length and width of a rectangle given that the length is 5 cm less than three times the width and the perimeter is 54 cm. To solve this, let's denote the width of the rectangle as 'w' and the length as 'l'. The relationship between the length and width can be expressed as 'l = 3w - 5 cm'. The perimeter (P) of a rectangle is given by P = 2l + 2w, and substituting our expressions in terms of 'w' into the formula gives us 2(3w - 5) + 2w = 54. Simplifying and solving for 'w' gives us the width. Subsequently, we can substitute this width into the equation for length to find 'l'.
So, let's start by setting up the equation:
2(3w - 5) + 2w = 54
6w - 10 + 2w = 54
8w - 10 = 54
8w = 64
w = 8 cm
Now we substitute w = 8 cm into the length formula:
l = 3(8) - 5
l = 24 - 5
l = 19 cm
Therefore, the width of the rectangle is 8 cm and the length is 19 cm.

The cost of producing x soccer balls in thousands of dollars is represented by h(x) = 5x + 6. The revenue is represented by k(x) = 9x – 2. Which expression represents the profit, (k – h)(x), of producing soccer balls?
Answer:
(K-h) (x) = 4(x-2)
Step-by-step explanation:
The cost of producing x soccer balls in thousands of dollars is represented by h (x) = 5x + 6
Revenue generated is represented by K(x) = (9x-2)
Them ( K-h) (x) will represent
( K-h )x = cost of revenue - production
= profit
( K-h )x = K(x) - h(x)
= (9x-2) - (5x + 6)
= (9x - 5x) - (2+6)
= 4x - 8
Profit = (K-h) (x) = 4(x-2)

Andy ran 436.8 meters in 62.08 seconds. Use place value, multiplication with powers of 10, or equivalent fractions to explain what is happening mathematically to the decimal points in the divisor and dividend before dividing!!
IM GIVING AWAY ALL MY POINTS FOR THIS!!
Answer:
If you round, he runs 7 meters in a second.
436.8 m 62.08 s
x m 1 s
(436.8 X 1) / 62.08 = 7.03 m/s
7.03 m 1 s
y m 1/10 s
(7.03 X 0,1 ) /1 = 0,703 m
Step-by-step explanation:
To find Andy's running speed, divide distance by time, adjusting for decimals by multiplying both the divisor and dividend by powers of 10, shifting the decimal point to simplify division.
To calculate Andy's running speed, you would divide the distance he ran (436.8 meters) by the time it took (62.08 seconds). When you divide or multiply decimals by powers of 10, the decimal point is shifted. For instance, if we multiply or divide a number like 1.9436 by 10, 100, or 1000, our decimal point moves to the right or left accordingly. If dividing by 10, it moves one place to the left; by 100, two places; by 1000, three places, turning our number into 0.19436, 0.019436, and 0.0019436 respectively. The same principle applies to Andy's calculation, where the numbers would be easier to handle if we removed the decimal points by multiplying both the divisor and dividend by the same power of 10. Consequently, when dividing 436.8 by 62.08, we can multiply both by 100 to remove the decimal and divide 43680 by 6208, ultimately giving the same answer but with much simpler arithmetic.
Write a linear factorization of the function. f(x) = x4 + 4x2
Final answer:
The function f(x) =[tex]x^4 + 4x^2[/tex] is factored using the difference of squares method to achieve its linear factorization. The final factorization over complex numbers is f(x) = x * x * (x + 2i) * (x - 2i).
Explanation:
To write a linear factorization of the function f(x) = [tex]x^4 + 4x^2[/tex] to find the factors of the polynomial that are linear, meaning each factor will be of the form (x - c) where c is a constant.
First, notice that the given polynomial is a quadratic in form, where [tex]x^2[/tex] is our variable. This gives us [tex]f(x) = (x^2)2 + 4(x^2)[/tex]which resembles the sum of squares [tex]a^2 + 2ab + b2 = (a + b)^2.[/tex] However, we only have [tex]a^2 + 2ab[/tex], with b being 2, and a being [tex]x^2[/tex].
To create a perfect square, we can write it as a difference of squares by adding and subtracting 4: [tex]f(x) = (x^2 + 2)^2 - (2)^2[/tex]. This can be factored further using the difference of squares formula, giving us[tex]f(x) = (x^2 + 2 + 2)(x^2 + 2 - 2)[/tex] which simplifies to [tex]f(x) = (x^2 + 4)(x^2).[/tex]
The linear factorization can be found by recognizing that x2 is already a product of linear factors x * x. Since [tex]x^2[/tex] + 4 cannot be factored over the real numbers, we need to use complex numbers to factor it further.
Using the sum of squares, we get [tex]x^2[/tex] + 4 = (x + 2i)(x - 2i), resulting in the final linear factorization over the complex numbers: f(x) = x * x * (x + 2i) * (x - 2i).
