Three vertices of a parallelogram are shown in the figure below.
Give the coordinates of the fourth vertex.
(-4,9)
(-6,-5)
(1.-7)
Answer:
(3, 7)
Step-by-step explanation:
Given that points (-4,9), (-6,-5), and (1.-7) are three vertices of a parallelogram with segments connecting them in order, you want the point that is the fourth vertex.
ParallelogramThe diagonals of a parallelogram bisect each other, which means they have the same midpoint:
((-4, 9) +(1, -7))/2 = ((-6, -5) +(x, y))/2
Multiplying by 2 and subtracting the point on the right side, we have ...
(-4, 9) +(1, -7) -(-6, -5) = (x, y)
(-4 +1 +6, 9 -7 +5) = (x, y) = (3, 7)
The fourth vertex is (3, 7).
__
Additional comment
In general three points can define three possible parallelograms. Here, the segments connecting the points are presumed to be the sides of the parallelogram, so reducing the number of possibilities to just one.
The fact that the diagonal midpoints are the same is useful for solving a variety of problems involving parallelograms.

Answer:
y < x + 6
Step-by-step explanation:
The line is broken so that mean that points on the line are not a solution. The shaded part is below the line so that means that we would use the less than sign.
The slope is 1. Rise over Run. We go up 1 and right 1. 1/1 = 1. The graph crossed the y axis at 6
To find the slope of the line given the points (-6,0) and (0,6), we can use the formula: m = (y2 - y1) / (x2 - x1).
m = (6 - 0) / (0 - (-6)) = 6/6 = 1
Using point-slope form, we can write the equation of the line as:
y - 0 = 1(x + 6)
y = x + 6
To get the inequality we just need to change the equation to the inequality by replacing the equal sign with the inequality sign.
So the linear inequality for the points (-6,0) and (0,6) is:
y > x + 6
If x equals 44, find the measures of angles 1 and 2
The measurement of ∠1 = 136° and ∠2 = x = 44°, using Vertically opposed angles.
What are Vertically opposed angles?Vertical angles are produced when two lines intersect at a point. They are always on an even playing field. Or, to put it another way, whenever two lines cross or intersect, four angles are formed. As we can see, two opposed angles are equal and are referred to as vertical angles.
They are also referred to as "vertically opposed angles" because of their position directly opposite one another.
∠x = 44
∠2 = x = 44
∠1 + ∠2 = 180
∠1 = 180 - 44 = 136°
Therefore, the angles are 36° and 144°.

A child is sitting at the edge of a merry-go-round that has a 3m radius. If the merry-go-
round rotates through 120 degrees, how far does the child end up from his starting
point. Note that you are trying to find the straight line distance from the starting point to
the ending point, not the distance around the circle that the child traveled.
Answer: To find the distance the child travels, we can use the arc length formula: s = r * θ, where s is the arc length, r is the radius of the circle, and θ is the angle of rotation in radians. Since the merry-go-round has a radius of 3m and rotates through 120 degrees, we can convert the angle to radians by multiplying by pi/180.
120 degrees * pi/180 = 2pi/3 radians
Now we can plug in the values into the arc length formula:
s = r * θ
s = 3 * (2pi/3)
s = 2pi
The distance the child travels is 2pi meters, which is the circumference of the circle.

which of the following are correct converstions between a teragram (tg) and a gram? select any that apply. group of answer choices 1 tg
3 teragrams is equal to 3 million grams.
The formula to convert teragrams (tg) to grams (g) is: grams = teragrams x 1000000000000. For example, to convert 15 teragrams to grams, we multiply 15 by 1000000000000, which equals 1.5e+13 or 150000000000000 grams. To convert grams to teragrams, we reverse the formula by dividing grams by 1000000000000. For example, to convert 1500000000000 grams to teragrams, we divide 1500000000000 by 1000000000000, which equals 1.5 teragrams.1 tg (teragram) is equal to 1000000 g (grams).
To calculate how many grams are in a teragram, you can use the following formula:
Grams = Teragrams x 1,000,000
For example, let's say you have 3 teragrams. To find out how many grams this is, you would use the formula above:

Question 2:
Part A:
Reshanda was invited for coffee at 2:00 pm, but she normally goes to sleep at 10:00 pm. If a 16-oz coffee has 122 mg of caffiene, and the half-life of caffiene is 5.5 hours, how much caffiene would still be in her system at bedtime? (Round your answer to the nearest tenth of a milligram)
Part B:
Suppose Reshanda cannot sleep if she has 15 or more mg of caffeine in her system. How many hours before she goes to sleep could she drink a 16-oz coffee? (Round your answer to the nearest tenth of an hour)
Assuming the exponential decay model applies, a similar calculator will cost $10.19 in the year 2023.
Question 2:
Part A:
The amount of caffiene that would still be in her system at bedtime is 28.36 mg
Part B:
The hours before she goes to sleep which she could drink a 16-oz coffee is 6.51 hours.
How do we determine the values?The average cost of a scientific calculator was $96.50 in 1970 and $22 in 2016. Using the exponential decay model, the cost of a similar calculator in 2023 would be $10.19.
Question 2:
Part A:
Reshanda was invited for coffee at 2:00 pm, and she normally goes to sleep at 10:00 pm. The half-life of caffeine is 5.5 hours. To determine how much caffeine would still be in her system at bedtime, we can use the formula:
C(t) = C0(1/2)^(t/T),
where C(t) is the amount of caffeine in her system at time t, C0 is the initial amount of caffeine (122 mg), t is the time in hours since she consumed the coffee, and T is the half-life of caffeine (5.5 hours).
At 10:00 pm, 8 hours after drinking the coffee, t = 8 hours. Plugging these values into the formula and solving for C(t), we get: C(8) = 122(1/2)^(8/5.5) = 28.36 mg
Part B:
Reshanda cannot sleep if she has 15 or more mg of caffeine in her system. We can use the formula from part A to solve for the time t when the caffeine level drops below 15 mg.
C(t) = 15, C0 = 122, T = 5.5
15 = 122(1/2)^(t/5.5)
then we can isolate t:
t = 5.5 * ln(122/15) = 6.51 hours
So, Reshanda could drink the coffee 6.51 hours before she goes to sleep.

In the field of machine learning, specifically the problem of statistical classification (in unsupervised learning, it is typically referred to as a matching matrix), a confusion matrix, also known as an error matrix, is a specific table structure that enables visualizing the performance of an algorithm.
The literature describes both iterations of the matrix, where each row represents instances in an actual class and each column represents instances in a predicted class. Since it is straightforward to tell whether the system is combining two classes, the name was chosen (i.e. commonly mislabeling one as another).
accuracy is given by the formula :
Accuracy(%) = (true positive + true negative)/(positive + negative)
Here TP true positive =10

find the solution of the system of equations -7 -7y =-41 x-6y = -37
Answer:
x = -55/7, y = 34/7
Step-by-step explanation:
Solve the following system:
{-7 y - 7 = -41 | (equation 1)
-6 y + x = -37 | (equation 2)
Express the system in standard form:
{0 x - 7 y = -34 | (equation 1)
x - 6 y = -37 | (equation 2)
Swap equation 1 with equation 2:
{x - 6 y = -37 | (equation 1)
0 x - 7 y = -34 | (equation 2)
Multiply equation 2 by -1:
{x - 6 y = -37 | (equation 1)
0 x + 7 y = 34 | (equation 2)
Divide equation 2 by 7:
{x - 6 y = -37 | (equation 1)
0 x + y = 34/7 | (equation 2)
Add 6 × (equation 2) to equation 1:
{x + 0 y = -55/7 | (equation 1)
0 x + y = 34/7 | (equation 2)
Collect results:
Answer: {x = -55/7, y = 34/7
The figure below represents a rectangular prism net. The rectangles labeled B represent both bases of the prism. What is the difference between the lateral and total surface area of the prism? (Hint: What are the only rectangles you are finding the area of?)
A : 156in
B : 128in
C : 30in
D: 48in
The total surface area and lateral area have a difference of 48 square inches. (Correct choice: D)
How to difference lateral area and total surface area in a right prism
In this problem we find a right prism with a rectangular base, of which we must determine its lateral area and its total surface area, both in cubic inches.
Lateral area is the sum of all faces A and C (four rectangles), whereas total surface is the sum of lateral area and all faces B (two rectangles). Area formula for rectangles is shown below:
A = w · l
Where:
w - Width, in inches.l - Length, in inches.A - Area, in square inches.Now we proceed to determine the lateral area and the total surface area of the prism:
Lateral area
A' = 2 · (3 in) · (5 in) + 2 · (8 in) · (5 in)
A' = 30 in² + 80 in²
A' = 110 in²
Total surface area
A = A' + 2 · (8 in) · (3 in)
A = 110 in² + 48 in²
A = 158 in²
And the difference between total surface area and lateral area is equal to 48 in².

5 6 A cubical tank of edge 42 cm was filled with water up to of its height. The water in the tank was used to fill up identical jugs of 1.3 litres each. During the process, 2.45 litres of water was spilled. Find the maximum number of jugs that were fully filled.
Answer:
The volume of the cubical tank is 42 cm x 42 cm x 42 cm = 84,764 cm^3
If the tank is filled up to the height of its edge, it means that the water filled up to the height of 42cm, and the volume of the water filled is 42cm x 42cm x 42cm = 84,764 cm^3
The volume of 1 jug = 1.3 litres = 1300 cm^3
The total volume of water spilled = 2.45 litres = 2450 cm^3
The total volume of water that can be filled into jugs = total volume of water in tank - volume spilled = 84764 - 2450 = 82314 cm^3
If we divide the total volume of water that can be filled into jugs by the volume of 1 jug, we get 82314/1300 = 63.6
The maximum number of jugs that were fully filled is 63, as the fraction of 0.6 jugs is not possible.
