Applying the midpoint formula, the coordinates of point M are: (-3, -4).

The midpoint formula is given as, (x, y) = [(x2 + x1)/2, (y2 + y1)/2].

Given the following:

N(x, y) = (1.5, 2.5)

P(x1, y1) = (6, 9)

M(x2, y2) = (?, ?)

Plug in the values into the midpoint formula

N(1.5, 2.5) = [(x2 + 6)/2, (y2 + 9)/2]

Isolate each coordinate

1.5 = (x2 + 6)/2

2(1.5) = x2 + 6

3 = x2 + 6

3 - 6 = x2

x2 = -3

2.5 = (y2 + 9)/2

5 = y2 + 9

5 - 9 = y2

y2 = -4

Therefore, applying the midpoint formula, the coordinates of point M are: (-3, -4).

Using supplementary angles, it is found that the value of x is of x = 10.75.

Supplementary angles are angles whose measures add to 180º.

An entire pizza is 360º, hence half the pizza is 180º, meaning that angles AOB and BOD are supplementary.

Their measures are given as follows:

Since they are supplementary, they add to 180º and we can add their measures and solve for x as follows:

2x - 4 + 14x + 12 = 180

16x = 172

x = 172/16

The total number of seats are there is row 16 is 65.

In Arithmetic Progression, the difference between two different arithmetic orders is a fixed number (AP). Arithmetic Sequence is another name for it.

We'd come along through a few specific terms in AP that had been labeled as:

As shown below, the AP can also be referred to in terms of common differences.

Now, as the values given in the question;

There are total 16 rows in the arena.

Thus, n = 16.

There are 20 seats present in row 1.

Consider the first term as 'a₁' = 20.

Similarly, there are 23 seats present at row 2.

Consider 'a₂' = 23 is the second term.

Now, calculate the common difference;

d = a₂ - a₁  

Put the values in the 'd'.

d = 23 - 20 = 3.

Now, compute the total number of seats in 16th row bu nth formula.

n-th term:  an = a + (n − 1) × d

a₁₆ = a₁ + (n - 1)d

a₁₆ = 20 + (16 - 1)3

a₁₆ = 20 + 45

a₁₆ = 65

Therefore, the total number of seats present in the 16th row is 65.

Answer:

5 - 17 = -12

-12/4 = -3

Answer:

number is - 3

Step-by-step explanation:

let the number be n then the product ( multiplication ) of n and 4 is 4n , so

4n + 17 = 5 ( subtract 17 from both sides )

4n = - 12 ( divide both sides by 4 )

n = - 3

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the trigonometric equation be represented as A

Now , the value of A is

cos x + cos ( x + 2π/3 ) + cos ( x + 4π/3 ) = 0

Now , the value of cos A + cos B = 2 cos ( A + B / 2 ) cos ( A - B / 2 )

Substituting the values in the equation , we get

The height of the tree, which Dave is standing 66 feet away from, is 34 feet and 2.4 inches.

If Dave's and the tree's shadows end at the same point, then the length of the shadow of the tree must be the sum of Dave's shadow and his distance from the tree.

tree's shadow = Dave's shadow + distance from the tree

tree's shadow = 15 feet + 66 feet

tree's shadow = 81 feet

Using ratio and proportion, we can solve for the height of the tree.

Dave's height : height of tree = Dave's shadow : tree's shadow

let x = height of the tree

6 feet 4 inches : x = 15 feet : 81 feet

converting feet to inches (1 feet = 12 inches)

76 : x = 180 : 972

Solving for x by evaluating the proportion:

180 x = 76 (972)

Answer: 8/5

Step-by-step explanation:

The missing term in the sequence is A5 = 5 .

Let's assume for the sake of simplicity that the third term they provided you was >3, and the twenty-fifth is >25. As a result, you put 3 as A sub-one rather than specifying that A sub-3 is 3 and A sub-25 is 25. Here's where things become tough. Set A sub-23 to 25. (why? because 1 to 23 and 3 to 25 are equally distant.

A3=3, A25=25 } A1=3, A23=25

Apply the equation An = A1 + (n-1)D.

(Read: A-sub n = A sub 1 - the nth term - D)

A23(A sub-23)= 3 Plus (23-1)

D 25 = 3 + 22D \s-3 -3

22 = 22D

D = 1

Once more, An = A1 + (n-1)D.

A3 = A1 + (3-1) X 1

3 = A1 + 2

-2 -2

A1 = 1

An = 1 + (n-1) X 1

An = 1 + 1n - 1

An = 1n + 0

So you are left with the general formula An = 1n. You can use this formula to find any term in the sequence, all you got to do is plug in (An) the number you want. In this case, plug in A sub-5 if you want to find the fifth term. You get

An = 1n

A5 = 1X5

A5 = 5

The fifth term in the sequence is 5. (it goes 1,2,3,4,,5,..)

The equation of the circle that passes through the point (-6 , -4) and has a center located at the origin is x^2 + y^2 = 52.

Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (-6 , -4).

radius = distance = √(x2 - x1)^2 + (y2 - y1)^2

radius = √(-6 - 0)^2 + (-4 - 0)^2

radius= √36 + 16

radius = √52

The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.
