5 Kari makes a kite in the form of a parallelogram, EDGF, as shown in the diagram. Its diagonals [DF] and [EG] intersect at point H. She plots the vertices on a coordinate system with the following coordinates:
D(3,6), G(1,3), H(4, y) and E(x, 6). Find the values of x and y.
Answer:
The values of x and y are;
x = 7 and y = 4.5
Step-by-step explanation:
The question is a word problem, given that the shape of the kite Karl makes is a parallelogram
The coordinates of the vertices are;
D(3, 6), G(1, 3), H(4, y), and E(x, 6)
From the properties of a parallelogram we have;
The diagonals bisect each other
Therefore;
GH = EH = 1/2·GE
Therefore, we have;
The coordinates of the point H = The coordinate of the midpoint of the line EG
The coordinates of the midpoint of a line with end points, (x₁, y₁) and (x₂, y₂) is given as follows;
The coordinates of the midpoint of a line = ((x₁ + x₂)/2, (y₁ + y₂)/2)
Therefore;
The coordinates of the midpoint of the line EG are ((1 + x)/2, (3 + 6)/2)
Given that the midpoint of EG is the point H and the coordinate of the point H is (4, y), we have;
(1 + x)/2 = 4, therefore;
2 × 4 = 1 + x
8 = 1 + x
x = 8 - 1 = 7
Similarly, we have from the coordinate of point H which is given as follows;
((1 + x)/2, (3 + 6)/2) = (4, y)
y = (3 + 6)/2 = 9/2 = 4.5
Therefore, x = 7, y = 4.5.
Parallel sides of a parallelogram have the same slope
The values of x and y are 6 and 3, respectively.
The coordinate points are given as:
[tex]\mathbf{D =(3,6)}[/tex]
[tex]\mathbf{G =(1,3)}[/tex]
[tex]\mathbf{H =(4,y)}[/tex]
[tex]\mathbf{E =(x,6)}[/tex]
Lines DG and HE are parallel.
This means that they have the same slope (m)
The slope is calculated as:
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
So, we have:
[tex]\mathbf{m_{DG} = \frac{3 - 6}{1 - 3}}[/tex]
[tex]\mathbf{m_{DG} = \frac{- 3}{- 2}}[/tex]
[tex]\mathbf{m_{DG} = \frac{3}{2}}[/tex]
Similarly
[tex]\mathbf{m_{HE} = \frac{6 - y}{x - 4}}[/tex]
The slopes are equal.
So, we have:
[tex]\mathbf{\frac{6 - y}{x - 4} = \frac 32}[/tex]
By comparison:
[tex]\mathbf{6 - y = 3}[/tex] and [tex]\mathbf{x - 4 = 2}[/tex]
Solve for y in [tex]\mathbf{6 - y = 3}[/tex]
[tex]\mathbf{y = 3}[/tex]
Solve for x in [tex]\mathbf{x - 4 = 2}[/tex]
[tex]\mathbf{x = 6}[/tex]
Hence, the values of x and y are 6 and 3, respectively.

2) translation: 1 unit left and 2 units up
Answer:
[tex](x,y)\rightarrow(x-1,y+2)[/tex]
Step-by-step explanation:
One unit left would be subtracting 1 from the pre-image's x-value.
Two units up would be adding 2 to the pre-image's y-value.
The translation rule would be:
[tex](x-1,y+2)[/tex]
Hope this helps.
The coordinates after the translation of 1 unit left and 2 units up will be (x-1,y+2).
What is geometric transformation?It is described as the alteration of the geometric body's form and coordinates. It is also known as a two-dimensional transformation. Rotation, translation, reflection, and gliding translation are just a few of the geometric transformations that may affect geometry.
It is given that the coordinates of the points are (x,y)
We have to find the coordinates after the translation of 1 unit left and 2 units up.
A sort of transformation called a translation involves moving each point in a figure the same distance in the same direction.
The final unit would be to deduct 1 from the x-value of the pre-image. The pre-y-value images would be increased by 2 by moving two units higher.
Thus, the obtained coordinates will be (x-1,y+2).
The question is incomplete.
The complete question is" if the coordinates of the points are (x,y). What will be the coordinates after the translation of 1 unit left and 2 units up?

What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
Since the population of a certain city decreased by 43,000 people.
The negative sign indicates that the population decreased, which means there was a decrease in the quantity of 43,000 people.
Thus, we can population change is shown by -43,000.
Hence, a signed number to represent this population change is -43,000.

A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 6 feet per second. The elevator for the miners descends 16 feet per second. One day, the equipment elevator begins to descend. After 28 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 14 seconds? At that time, which elevator is deeper?
Answer:
equipment: -252 feet; miners: -224 feetequipment is deeperStep-by-step explanation:
The attached graph shows the depth of the elevators with respect to the time the miners' elevator started.
After 14 more seconds, the positions are ...
equipment: -6(42) = -252 feet relative to the surface
miners: -16(14) = -224 feet relative to the surface
The equipment elevator is deeper.

No time is thinking of a six digit number in which all the digits are the same the value of the digit in the thousands place is 8000 what is new Times number
Answer:
The number is 888888
Step-by-step explanation:
Here, we are interested in knowing the six digit number thought of by No time.
The clue we have here is that the six digit number has same value of digit for all its constituent.
Thus, if the digit in the thousands place is 8,000, then it actually means that it carries a value of 8 and thus, all the digits in the number is 8 alone.
So the 6 digit number is 888888

Emily and Hunter tracked the average temperature in their city for the past 8 days. They recorded their temperature findings in this list 66°F, 57°F, 61°F, 65°F, 54°F, 62°F, 59°F, 56°F
What is the mean absolute deviation of this data set?
Enter your answer in the box.
Answer:
The mean absolute deviation = 3.5°F
Step-by-step explanation:
The sum of the given temperatures, ∑T, is found as follows;
∑T = 66°F + 57°F + 61°F + 65°F + 54°F + 62°F + 59°F + 56°F = 480°F
The number of days, n, over which the temperature was tracked = 8 days
Therefore, the mean, [tex]\bar x[/tex], of the data set = ∑T/n = 480°F/8 = 60°F
The mean absolute deviation is given by the following formula;
[tex]Mean \ absolute \ deviation = \frac{\sum \limits_{i = 1}^{n} \left | x_i - \bar x \right | }{n}[/tex]
Therefore, we have;
66 - 60 = [tex]\left | 6\right |[/tex] = 6
57 - 60 = [tex]\left | -3\right |[/tex] = 3
61 - 60 = [tex]\left | 1\right |[/tex] = 1
65 - 60 = [tex]\left | 5\right |[/tex] = 5
54 - 60 = [tex]\left | -6\right |[/tex] = 6
62 - 60 = [tex]\left | 2\right |[/tex] = 2
59 - 60 = [tex]\left | -1\right |[/tex] = 1
56 - 60 = [tex]\left | -4\right |[/tex] = 4
The mean absolute deviation is therefore;
The mean absolute deviation = (6 + 3 + 1 + 5 + 6 + 2 + 1 + 4)/8 = 3.5°F.

can you help me estimate 102.3+4.7
Answer: 107
Step-by-step explanation:
102.3 can be rounded down to 102 (because the 3 at the end of the number is less than 5)
4.7 can be rounded up to 5 (because the 7 at the end of the number is greater than 5).
102.3 → estimate = 102
4.7 → estimate = 5
estimated sum = 107
Note that estimating the sum is NOT the same as simply adding the numbers and then rounding the sum.
