A(-1, 2) and C(3, 4) are opposite vertices of a rhombus ABCD. Find the coordinates of the points where the diagonals intersect

Answers

Since M and N have the same coordinates, we know that AC and BD intersect at the point (1,3). The coordinates of the intersection point are (1,3).

What is rhombus?

A rhombus is a special type of parallelogram in which all four sides are of equal length. Equivalently, a rhombus is a quadrilateral with four sides of equal length.

Since ABCD is a rhombus, its diagonals AC and BD are perpendicular bisectors of each other, and they intersect at their mutual midpoint M.

The midpoint M of AC is the average of the coordinates of A and C, namely:

M = ((-1+3)/2, (2+4)/2) = (1, 3)

Similarly, the midpoint of BD is the average of the coordinates of B and D. Since we don't know the coordinates of B and D, we need to find them first.

The other two vertices of the rhombus are obtained by reflecting A and C about the midpoint M, since opposite sides of a rhombus are parallel and equal in length. To do this, we subtract the coordinates of M from those of A and C, and then add them to M:

B = 2M - A = 2(1,3) - (-1,2) = (3,4)

D = 2M - C = 2(1,3) - (3,4) = (-1,2)

Now we can find the midpoint of BD:

N = ((3-1)/2, (4+2)/2) = (1, 3)

Since M and N have the same coordinates, we know that AC and BD intersect at the point (1,3). Therefore, the coordinates of the intersection point are (1,3).

At which point do the lines y=4x+1 and y=2x-1 intersect

Answers

The lines having linear equation y=4x+1 and y=2x-1 intersect at the point (-1, -3).

What is a linear equation, exactly?

A linear equation is an algebraic equation of the first degree that describes a line in a two-dimensional plane. It is an equation of the form y = mx + b, where x and y are variables, m is the slope of the line, and b is the y-intercept. The slope represents the rate of change of y with respect to x, while the y-intercept represents the point at which the line crosses the y-axis

Now,

To find the point of intersection between the lines y=4x+1 and y=2x-1, we can set the two equations equal to each other or we can graph these and find the intersection point.

1.

4x+1 = 2x-1

Simplifying this equation, we get:

2x = -2

x = -1

Now, we can substitute this value of x into either equation to find the corresponding value of y:

y = 4x+1 = 4(-1)+1 = -3

Therefore,

               the lines y=4x+1 and y=2x-1 intersect at the point (-1, -3).

and (13.5, 12)
.

How long is each side of the park?

Answers

The length of each side of the hexagon is 13 units long, which is equal to length of the park.

What is the length of each side of the park?

In order to determine the length of every side of the hexagon, it is necessary to compute the distance between each pair of neighboring vertices.

This can be accomplished by employing the distance formula, which is represented as follows:

d = √( ( x₂ - x₁ )² + ( y₂ - y₁ )² ).

To facilitate the process, we will designate the vertices as A, B, C, D, E, and F in sequence, with A being the vertex at the top.

Then, the length of side AB is calculated as follows:

|AB| = √((38.5-26.5)² + (7-12)²)

|AB| = √((12)² + (-5)²)

|AB| = √(144 + 25)

|AB| = √169

|AB| = 13

Similarly, we can calculate the length of each side:

|BC| = √( (26.5-38.5)² + (2-7)² ) = 13

|CD| = √( (13.5-26.5)² + (2-2)² ) = 13

|DE| = √( (1.5-13.5)² + (7-2)² ) = 13

|EF| = √( (13.5-1.5)² + (12-7)² ) = 13

|FA| = √( (26.5-13.5)² + (12-12)² ) = 13

A jar contains 3 red marbles numbered 1 to 3 and 7 blue marbles
numbered 1 to 7. A marble is drawn at random from the jar. Find the
probability that the marble is blue AND even-numbered.

Answers

The probability of drawing the blue and even-numbered marble from the given jar is 3/10.

The given problem can be solved using the concept of Probability. Let's see how to solve it.

Step 1: Total Number of Marbles in the Jar

Number of red marbles in the jar = 3

Number of blue marbles in the jar = 7

Total number of marbles in the jar = 3 + 7 = 10

Step 2: Find the Probability of Marble is Blue and Even Numbered

Number of blue marbles which are even-numbered = 3 (Blue marbles numbered 2, 4, and 6 are even-numbered marbles)

Total number of marbles in the jar = 10

Probability of marble is blue and even-numbered = Number of blue marbles which are even-numbered / Total number of marbles in the jar = 3/10

So, the required probability of drawing the blue and even-numbered marble is 3/10.

Solve for x.

Answers

Answer: x = 24

Step-by-step explanation:

To solve for x, we need to simplify the left side of the equation first by combining like terms:

4x - 2 + 3x + 14 = 180

7x + 12 = 180

Next, we will isolate the variable by subtracting 12 from both sides:

7x + 12 - 12 = 180 - 12

7x = 168

Finally, we will solve for x by dividing both sides by 7:

7x/7 = 168/7

x = 24

Therefore, the solution to the equation 4x-2+3x+14=180 is x = 24.

a. The perimeter in the scale is 36 centimeters

The area in the scale drawing is 80 square centimeters.

b.  The actual perimeter is 40 millimeters.

The actual area is 937.5 square millimeters. ​

To find the perimeter of the icon in the scale drawing, you need to add up the length of all its sides. Using the ruler provided, measure the length and width of the icon and round them to the nearest half centimeter. Then, add up the length and width and multiply by 2 to get the perimeter.

a. Assuming the scale of the drawing is 1 cm : 2 units, the length of the icon in the drawing would be 2 x 5 = 10 units and the width would be 2 x 4 = 8 centimeters.

The perimeter in the scale drawing would be 2 x (length + width) = 2 x (10 + 8) = 36 cm (rounded to the nearest half-centimeter).

The area in the scale drawing would be length x width = 10 x 8 = 80 square cm.

b. Assuming the scale of the drawing is 1 cm : 2 units, the actual length of the icon would be 2.5 cm / 2 = 1.25 units and the actual width would be 1.5 cm / 2 = 0.75 units.

The actual perimeter would be 2 x (length + width) = 2 x (1.25 + 0.75) = 4 cm = 40 mm.

The actual area would be length x width = 1.25 x 0.75 = 0.9375 square cm = 937.5 square mm.

Answers

The solution of the system of equation is (3, 5) and (–4, 12) [option A]

The given system of equations is:

x + y = 8

y = x² – 4

To solve for x and y, we can substitute the second equation into the first equation for y:

x + (x² - 4) = 8

Simplifying, we get:

x² + x - 12 = 0

Now we can use the quadratic formula to solve for x:

x = (-b ± √(b² - 4ac)) / 2a

where a = 1, b = 1, and c = -12

x = (-1 ± √(1² - 4(1)(-12))) / 2(1)

x = (-1 ± √(1 + 48)) / 2

x = (-1 ± 7) / 2

Solving for x gives us two possible values: x = 3 or x = -4.

To find the corresponding values of y for each value of x, we can substitute them into either of the original equations. Using y = x² - 4:

When x = 3, y = 3² - 4 = 5

When x = -4, y = (-4)² - 4 = 12

Therefore, the solution to the system of equations is (3, 5) and (-4, 12), which is answer choice (a).

we know the slope, we can use one of the points, say (2, -4), and the slope to find the y-intercept, b. Use the slope intercept to form the equation of a line:

y = mx + b, and substitute in the slope and coordinates of one of the points:

-4 = (-3)(2) + b

Simplifying this equation, we get:

b = -4 + 6

= 2

Therefore, the equation of the line that passes through the given points (2, -4), (3, -7), (4, -10), and (5, -13) is: y = -3x + 2

Answers

Therefore, the solutions to the equation 7u² - 56 = 0 are u = 2.83 and u = -2.83 (rounded to the nearest hundredth).

Answer: u = 2.83, -2.83.

What is equation?

An equation is a mathematical statement that asserts the equality of two expressions. It typically consists of two sides separated by an equals sign (=). The expressions on both sides of the equals sign are called the left-hand side (LHS) and the right-hand side (RHS) of the equation. The goal in solving an equation is to find the value or values of the variable(s) that make the equation true.

What is real numbers?

The real numbers are a set of numbers that includes all rational and irrational numbers. Real numbers can be represented on the number line, where every point corresponds to a unique real number. The real number system is denoted by the symbol R.

In the given question,

To solve the equation 7u² - 56 = 0, we can start by isolating the variable u by adding 56 to both sides of the equation:

7u² - 56 + 56 = 0 + 56

Simplifying the left side, we get: 7u² = 56

Dividing both sides by 7, we get: u² = 8

Taking the square root of both sides, we get: u = ±√8

Simplifying the square root, we get: u = ±2.83

Therefore, the solutions to the equation 7u² - 56 = 0 are u = 2.83 and u = -2.83 (rounded to the nearest hundredth).

Answer: u = 2.83, -2.83.

Reed's number cube numbered (1, 2, 3, 4, 5, 6) is rolled and a spinner with 4 sections (A, B, C, D) is spun. P(1 and A)

Answers

The probability of rolling a 1 and spinning section A on the spinner is 1/24.

To find the probability of rolling a 1 and spinning section A on the spinner, we need to first determine the total number of possible outcomes for the experiment. The number cube has 6 possible outcomes, and the spinner has 4 possible outcomes. Therefore, the total number of possible outcomes for the experiment is 6 x 4 = 24.

Next, we need to determine the number of outcomes that meet the criteria of rolling a 1 and spinning section A. Rolling a 1 has a probability of 1/6, and spinning section A has a probability of 1/4.

The probability of both events occurring simultaneously is the product of the two probabilities, which is (1/6) x (1/4) = 1/24.

This means that out of the 24 possible outcomes, only one outcome will result in rolling a 1 and spinning section A on the spinner.
