Slope PQ = 1 / 5, Slope QR = -1. Slope RS = - 1/4. Slope of SP = -5/2. No slopes and length of the segments are same the quadrilateral PQRS is a generic quadrilateral.

Generally speaking, a quadrilateral has four segments and is a type of polygon. The term "generic" denotes the absence of any additional characteristics for this quadrilateral. For instance, its opposite sides and angles might or might not be parallel and equal, respectively.

The given coordinates are:

P (3, 4)

Q (8, 5)

R (5, 8)

S (1, 9)

The slope of the line is given as:

m = (y2 - y1) / (x2 - x1)

Slope PQ = (5 - 4) / (8 - 3) = 1 / 5

Slope QR = (8 - 5) / (5 - 8) = 3 / -3 = -1

Slope RS = (9 - 8) / (1 - 5) = 1 / -4 = - 1/4

Slope of SP = (4 - 9) / (3 - 1) = -5/2

The length of the segment is given as:

√(x2 - x1)² + (y2 - y1)²

Length PQ = √(8-3)² + (5 - 4)² = √25 + 1 = √26

Length QR = √(5 - 8)² + (8 - 5)² = √9 + 9 = √18

Length RS = √(1 - 5)² + (9 - 8)² = √16 + 1 = √17

Length SP = √(3-1)² +(4 - 9)² = √4 + 25 = √29

Since, no slopes and length of the segments are same the quadrilateral PQRS is a generic quadrilateral.

Answer:

Mark's mass is 26 kg.

Step-by-step explanation:

Average mass of Jeremy, Mark and Zack = 28kg

Average mass of Jeremy and Zack = 29 kg

Let,

Jeremy's mass = x

Mark's mass = y

Zack's mass = z

Average of three of them = \(\frac{Jeremy's mass + Mark's + Zack's}{3}\)

28 = \(\frac{x+y+z}{3}\\\)

\(28*3 = x+y+z\\84 = x+y+z\)

x+y+z = 84     Eqn 1

\(29 =\frac{x+z}{2}\\58=x+z\\\)

x+z = 58    Eqn 2

Now putting value of x+z from Eqn 2 in Eqn 1

x + z + y = 84

58 + y = 84

y = 84 - 58

y = 26

Thereofore,

Mark's mass is 26 kg.

The total number of dried fruits is 21, while the total number of nuts is 33.

Given that there are 54 total fruits in the bag, mixed in the ratio of 11 to 7.

To start with, we first find the percentage of nut or dried fruit present. We are told 7:11. 7 + 11 = 18 This means that the percentage would be

7/18 = 38.889%

11/18 = 61.111%

This is the ratio in which they are shared. Then we move on to calculate the final contents in the bag.

7/18 * 54 = 21 fruits

11/18 * 54 = 33 nuts

This means that there are 33 nuts in the bag, to 21 dried fruits.

Answer: A. No, Only one Unique Triangle can Be Formed under These Conditions.

Step-by-step explanation: It is not possible for a triangle to have more than one vertex with internal angle greater than or equal to 90°, or it would no longer be a triangle.

The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.

The sum of the lengths of any two sides of a triangle is always larger than the length of the third side

Pythagorean theorem: The Pythagorean theorem is a theorem specific to right triangles. For any right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the two other sides. It follows that any triangle in which the sides satisfy this condition is a right triangle. There are also special cases of right triangles, such as the 30° 60° 90, 45° 45° 90°, and 3 4 5 right triangles that facilitate calculations. Where a and b are two sides of a triangle, and c is the hypotenuse

The ball is in the air for approximately 2.8 + √7 seconds, which rounds to 5.2 seconds when rounded to one decimal place.To write the equation in vertex form, we need to complete the square.

The given equation is h = -4.9t² + 27.44t + 0.584. We can rewrite it as:

h = -4.9(t² - 5.6t) + 0.584

Now, we want to complete the square inside the parentheses. To do this, we need to add and subtract the square of half the coefficient of t. In this case, the coefficient is -5.6, so we have:

h = -4.9(t² - 5.6t + (5.6/2)² - (5.6/2)²) + 0.584

Simplifying, we get:

h = -4.9((t - 2.8)² - 2.8²) + 0.584

Expanding further:

h = -4.9(t - 2.8)² + 4.9(2.8)² + 0.584

Thus, the equation in vertex form is: h = -4.9(t - 2.8)² + 34.328

b) The ball's height when it was hit can be found by evaluating the equation at t = 0:

h = -4.9(0 - 2.8)² + 34.328

h = -4.9(-2.8)² + 4.328

h = -4.9(7.84) + 34.328

h ≈ 0.784 meters

To find the time at which the ball reaches its maximum height, we can use the fact that the maximum height occurs at the vertex of the parabolic equation. The vertex of a parabola in the form h = a(t - h₀)² + k is given by (h₀, k). Comparing this to our equation, we can see that the vertex occurs at t = 2.8 and h = 34.328. Therefore, the ball reaches its maximum height at 2.8 seconds, and the maximum height is 34.328 meters.

The total time the ball is in the air can be determined by finding the time it takes for the ball to reach the ground. When the ball hits the ground, its height is 0. To find this time, we can set the equation equal to 0 and solve for t:

0 = -4.9(t - 2.8)² + 34.328

4.9(t - 2.8)² = 34.328

(t - 2.8)² ≈ 7

t - 2.8 ≈ ±√7

t ≈ 2.8 ± √7

Since time cannot be negative in this context, we can ignore the negative value.

Step-by-step explanation:

the funny thing with equations is we can transform them (as long as we do every operation in both sides), and we can even add them up or subtract from each other to get new equations that are maybe simpler to solve.

to eliminate x i would recommend to multiply the first equation by 4, and the second equation by 5 and then subtract equation 2 from equation 1 (comparable term by comparable term).

5x - 2y = 10

4x - 3y = 15

would then turn into

20x - 8y = 40

- 20x - 15y = 75

------------------------

0 7y = -35

y = -35/7 = -5

now we can pick any original equation to solve for x.

e.g.

5x - 2×-5 = 10

5x + 10 = 10

5x = 0

Step-by-step explanation:

(1) The value of x is determined as 16.8.

(2) The measure of length VX is calculated as 4.1.

(3) The measure of angle UWV is 69.5⁰.

The value of the missing lengths of the triangle is calculated by applying the following formula;

(1) For the two similar triangles, the value of x is calculated as follows;

20 / (28 - x) = 30 / x

20x = 30 (28 - x )

20x = 840 - 30x

20x + 30x = 840

50x = 840

x = 840 / 50

x = 16.8

(2) The measure of length VX is calculated by applying trig ratios.

tan 63 = 8 / VX

VX = 8 / tan 63

VX = 4.1

(3) The measure of angle UWV is calculated as follows;

angle T = 360 - (94 + 127) = 139

angle UWV = ¹/₂ x 139 (angle at circumference is half of angle at center)

Step-by-step explanation:

Answer:

the solution to the equation is m = 28/3, or approximately 9.3333

Step-by-step explanation:

To solve this equation, you need to get the variable, in this case "m," by itself on one side of the equation. To do this, you can start by isolating the fraction on the left side of the equation. You can do this by multiplying both sides of the equation by 2/3, which will cancel out the 2/3 on the left side:

3m/2/3 = 7

(2/3) * (3m/2/3) = (2/3) * 7

3m/2 = 7 * (2/3)

3m/2 = 14/3

Next, you can multiply both sides of the equation by 2 to get rid of the fraction on the left side:

(2) * (3m/2) = (2) * (14/3)

3m = 28/3

Finally, you can simplify the right side of the equation by dividing both sides by 3 to get the final solution:

(3m) / 3 = (28/3) / 3

m = 28/3

Therefore, the solution to the equation is m = 28/3, or approximately 9.3333.

Answer:

Maybe m = 14/9

Maybe m = 14

Step-by-step explanation:

It is not clear what you mean by the fraction on the left side.

Do you mean

3m/(2/3) = 7  ?

If so:

3m = 7 × 2/3

3m = 14/3

m = 14/9

Do you mean

(3m/2)/3 = 7   ?

If so:

3m/2 = 21

m = 21 × 2/3

m = 14

Do you mean something else?

Answer:

\(m = -\frac{23}{42}\)

Step-by-step explanation:

here is the equation for slope (m):

\(m = \frac{y_2-y_1}{x_2-x_1}\)

where:

y₂ = y-coordinate of 2nd point = -10

y₁ = y-coordinate of 1st point = 36

x₂ = x-coordinate of 2nd point = 93

x₁ =  x-coordinate of 1st point = 9

plug values into equation:

\(m =\frac{-10-36}{93-9} \\\\m = \frac{-46}{84} \\\)

reduce the fraction:

\(m = -\frac{23}{42}\)

It is reasonable to take the variance of the total income to be \(\sigma_x^2 + \sigma_y^2\).

When two variables are added, we have that:

The variances for each variable are given as follows:

Then the standard deviation of the total income, which is the combination of the income of the husband and of the wife, is calculated as follows:

\(\sigma = \sqrt{\sigma_x^2 + \sigma_y^2}\)

The variance is the square root of the variance, hence it is obtained as follows:

\((\sigma)^2 = (\sqrt{\sigma_x^2 + \sigma_y^2})^2 = \sigma_x^2 + \sigma_y^2\)

Which means that it is reasonable to take the variance of the total income to be \(\sigma_x^2 + \sigma_y^2\).

The problem asks if it is reasonable to take the variance of the total income to be \(\sigma_x^2 + \sigma_y^2\).
