Find the coordinates of the midpoint of stack J K with bar on top

J(-1,3), K(7,-1)

is it the answer 3,1 explain?!?!?!?

The triangle with vertices located at A(1 , 7), B(4 , 2), and C(7 , 7) has its centroid located at (4 , 16/3).

The centroid of a triangle is the point inside the triangle where the three medians intersect. The median of a triangle is the line the connects the midpoint of a side and the opposite vertex.

To get the centroid of a triangle, use the formula given by:

C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]

where C is the centroid of the triangle located at (x , y)

x1, x2, and x3 are the x-coordinate of the vertices of the triangle

y1, y2, and y3 are the y-coordinate of the vertices of the triangle

Let Point 1(x1 , y1) =  A(1 , 7)

Point 2(x2 , y2) = B(4 , 2)

Point 3(x3 , y3) = C(7 , 7)

Plug in the values in the formula.

C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]

C(x ,y) = [(1 +4 + 7)/3 , (7 + 2 + 7)/3]

C(x ,y) = (12/3 , 16/3)

C(x ,y) = (4 , 16/3)

For the given wire, the length of each piece of wire will be 76inch and 24 inch and quadratic equation will be x² - 100x + 1800 = 0

An algebraic equation of a second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.

Given,

Length of wire = 100 inches

Sum of the areas of two squares = 400 inch²

let length of one wire - x

the length of other wire will be - 100-x

Now, the area of the square = Side²

⇒ (x/4)² + ((100 - x)/4)² = 400

⇒ (1/4)²  (x² + 10000 + x² - 2(100)(x)) = 400

⇒ 10000 + 2x² + - 200x = 400 × 16

⇒ 2x² - 200x = 6400 - 10000

⇒ 2x² - 200x = - 3600

⇒ x² - 100x + 1800 = 0

⇒On solving for the value of x, we have x= 76 and 24

Now,

76/4 = 19,

24/4 = 6

So, we have the length of each wire as 76inch and 24inch

Step-by-step explanation:

= 5 + 12

= 17

Based on the information illustrated,

the relation r on s is reflexive. Therefore, it's true.

If every component of a set X is related to one another, then a relation R over that set is said to be reflexive.

If (a, a) R for all  A, that is, if every element of A is R-related to itself, or if aRa for every a A, then R is set to be reflexive.

In the example question, S is the set of all Park students, and R is a relation over S.

When a relationship is described as xRy, it signifies that x and y have the same biological mother.

This relation is obviously a reflexive relation. xRx means x and x has the same biological mother. In this case, the relation satisfies the requirement for all aR (a,a) R.

Therefore, it's true.

The  three segments  of Triangle is (1) 17 cm, 7 cm, 8 cm    

Here, 17 > 7 + 8 or 17 > 15

In any triangle, the sum of the lengths of any two sides of a triangle is always greater than the third side.

Therefore, the triangle is not possible.    

In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle. All triangles are enclosed in a single plane if all of the geometry is the Euclidean plane, however, this is no longer true in higher-dimensional Euclidean spaces.

Answer:

Length is 11 meters

Step-by-step explanation:

Formula we use,

→ P = 2(l + w)

Then the length of rectangle will be,

→ 32 = 2(L + 5)

→ 2L + 10 = 32

→ 2L = 32 - 10

→ L = 22/2

→ [ L = 11 m ]

Hence, the length is 11 meters.

Answer:

The number that gets raised, or multiplied by itself, is called the base. The number of times it is multiplied is called the exponent. Together this is called power.

Step-by-step explanation:

4n² + 5n - 636

splitting the middle term

4n² + 53n - 48n - 636 = 0

n(4n + 53) - 12(4n + 53) = 0

(n - 12) (4n + 53) = 0

n = 12 and n = -53/4

Ms Patel purchased 38 shares of stock a and 41 shares of stock b

Total amount invested in the two stocks = $825

Value of stock a = $12.41

Value of stock b = $8.62

Let the number of shares of stock a be x

Let the number of shares of stock b be y

Therefore, forming the equation we get:

x + y = 79------(1)

12.41x + 8.62y = 825

1241x + 862y = 82500 ------(2)

The required percentage of US states having their names starting with W is 8 %. This is gained by using the concept of percentage.

What do you mean by percentage?

The percentage is usually denoted by the symbol '%'. It is defined as the quantity or ratio which is being expressed in a fraction of 100, where 100 is the denominator.

Calculation of the percentage of US states having their names starting with W

Given:

Total states in US = 50

US states that start with the letter W = 4

Fraction in favour of the names of states starting with the letter W is given by = 4 / 50

Therefore the percentage of US states having their names starting with the letter W is equal to the fraction in favour * 100 %

= 4 / 50 * 100 %

= 4 * 2 %

= 8 %

Hence, the percentage of US states having their first letter as W is 8 %.

The translations for this problem are given, respectively, by:

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For the first translation, the orientation remains the same, just the positions changes, hence it is translated 9 units to the right and 2 units down.

For the second translation, the rule applied to each vertex was:

(x,y) -> (x,-y).

Hence it was reflected across the x-axis.

The probability, P (yellow), that a yellow chip is drawn from the bag is 4/19.

Probability is a term used in mathematics to determine the likelihood that an incident will take place as in this case is the likelihood that a yellow chip is drawn from the bag.

Probability can be given by the formula:

probability= Number of favorable outcomes ÷ Total number of possible outcomes

Hence, in this problem, the formula for probability will be:

P (yellow) = Number of yellow chips / Total number of chips in the bag

The total number of chips in the bag will be equal to the sum of the chips of all colors.

That is, total number of chips = 3 blue chips + 7 red chips + 4 yellow chips + 5 green chips

Total number of chips = 19 chips

So the probability of a yellow chip being drawn out will be:
