Step-by-step explanation:

I can't draw here, but I can tell and explain to you what happens to the points (incl. N).

remember the slope of lines, and what happens when we have to create a perpendicular slope (90°) ?

x and y in the slope ratio y/x go upside down and the sign flips (that means it flips for one of them).

a rotation by 90° follows the same principles.

x and y trade places, and for one of them the sign flips.

the only "difficult" trick is to determine, if the sign of x or of y flips.

let's look at N first.

N = (-5, -4)

the rotation counterclockwise takes it over into the 4th (bottom right) quadrant, where x values are positive.

aha, so the sign of x flips after x and y trade places, and we get

N' = (4, -5)

now for the other points

X = (-3, -2)

the same principle as for N

X' = (2, -3)

B = (-4, 1)

this is now moving from the 2nd (where y values are positive) to the 3rd quadrant (where x and y are negative).

so, again the sign of x flips after x and y trade places

B' = (-1, -4)

with the new coordinates of the points you can now easily draw the new triangle'.

Two cities have the same longitude .The latitude of the city a is 6 degree north and the latitude of city b is 30 degree north. Then the distance between two cities is 1658.844 miles

Two cities have the same longitude. the latitude of the city a is 6 degree north

and the latitude of city b is 30 degree north.

assume the radius of earth is 3960 miles.

find the distance between two cities.

City A = 6°   = 6°× π/180 =  0.1047 rad

City B = 30° = 30° × π /180= 0.5236 rad

multiply by π/180 to convert the degree to radian

radius of Earth = 3960 miles

to find out

distance between City A and City B

solution

we first get here central angle between A and B city is

central angle between A and B city = 0.5236rad - 0.1047 rad

and

now by arc length so  we get distance

distance = 3960 miles × (0.5236 rad - 0.1047rad )   as radius given 3960

distance = 1658.844 miles

Answer: The dimensions are 8 and 28

Two identical figures with all sides of equal length = Both are square

Solution :

The perimeter of a square is defined as the total length that its boundary covers. The perimeter of any closed geometrical shape is calculated by finding the distance around that shape. For a square, the perimeter can be calculated by finding the sum of all the sides. Since all four sides are equal, it is four times the length of each side of a square. Let us learn about perimeter of square in detail in this article.

Derivation of Perimeter of Square Formula

The perimeter of the square is defined as the total length of the boundary of a square. In order to calculate the perimeter of the square, we will find the sum of all of its sides. Since all sides of a square are equal for a square, with each side measuring "s" units, perimeter will thus be given as,

Perimeter of square = s + s + s + s

⇒ Perimeter of square = 4s, where "s" is the side length of the square.

Squares :

A square is a special kind of rectangle (an equilateral one) and a special kind of parallelogram (an equilateral and equiangular one). A square has four axes of symmetry, and its two finite diagonals (as with any rectangle) are equal. Bisection of a square by diagonal results in two right triangles.

The formula for the perimeter of a square is,

P = Side + Side + Side + Side. Or,

P = 4 × Side.

two identical figures with all sides of equal length the combined perimeter of the figure is 80centimeters

2(4*side ) = 80

8*side = 80

side = 10

length of one side =10

The coordinates of A are (3, 5).

According to the section formula-

If a point (x , y) divides a line in the ratio of m : n, where the two endpoints of the line are (x1, y1) and (x2, y2), then-

x = (nx1 + mx2)/ (m + n)

and y = (ny1 + my2)/ (m + n)

Here, M (4,6) is the midpoint of AB and B is (5,7)

Let the coordinates of A be (x2, y2)

Therefore,

x1 = 5, y1 = 7

x = 4, y = 6

Since, midpoint divides a line segment into two equal halves, m : n = 1 : 1

Now, substituting the values in the section formula we get-

4 = (5 + x2)/2

4 × 2 = 5 + x2

8 = 5 + x2

5 + x2 = 8

x2 = 8 - 5

x2 = 3

and 6 = (7 + y2)/2

6 × 2 = 7 + y2

12 = 7 + y2

7 + y2 = 12

y2 = 12 - 7

y2 = 5

Thus, the coordinates of A are (3, 5).

The inverse function of f(x) is; f-¹(x) = x³ + 5

To find the inverse of the function;

We should represent f(x) as y.

Now we have;

By taking the cube of both sides;

y³ = x - 5

By solving for x;

x = y³ + 5

By swapping x and y; we have;

y = x³ + 5

Answer:

  2√2 -√6

Step-by-step explanation:

You want to know the surd representation of the irrational number that rounds to 0.378937382.

The plural "surds" suggests this is the difference of two irrational roots. Looking at √(n+1) -√n, we find that √3 -√2 is the nearest, but does not match.

Looking at √(n+2) -√n, we find that √8 -√6 matches all 9 digits when rounded to the 9th decimal place. 20 digits of that value are ...

  0.37893738196301199941

The given number approximately matches the irrational value ...

  2√2 -√6

Additional comment

We programmed a calculator to find the values of √(n+2) -√n for n = 1..10. The result is attached. The 6th value matches, and corresponds to n=6.

In general, finding a surd representation of an arbitrary value seems to be a matter of trial and error. Perhaps your curriculum materials offer an algorithm.

Statements 2, 4 and 5 are true.

Let us check each statement one by one-

1. The square root of a positive number cannot be negative-

This statement is false. Let us take an example. If we take a number, say 4, 4 has 2 square roots- 2 and -2. This is because 2 × 2 = -2 × -2 = 4. Thus, the square root of a positive number can be negative.

2. All positive numbers have two square roots.

This statement is true. It follows from the example in 1 that any positive number has 2 square roots- one negative and one positive.

3. √18 = 9 because 9(2) = 18

The given statement is false. √18 ≠ 9. If √18 was equal to 9, then 9 × 9 must be 18. But 9 × 9 is 81. Hence, false.

4. √49 = 7 because 7(7) = 49

The x-intercept will be 5 , y-intercept will be 4 and the coordinate will be (x , y) = (5 , 4).

What is an intercept ?

An intercept is a location on the y-axis where the line's slope passes. It is the y-coordinate of the location where a line or curve crosses the y-axis.

It is given that we have to find out the x and y intercepts from the given graph.

We know that , a function's x-intercept is the value of x at the point where the graph crosses the horizontal axis, or when y = 0. As a result, while examining the function's graph, we find out that the x-intercept is equal to 5.

Similarly , The value of y when the graph crosses the vertical axis, or the value of y when x = 0, is the y-intercept of a function. As a result, while examining the function's graph, we find out that the y-intercept is equal to 4.

So , the coordinate will be (x , y) = (5 , 4).

Therefore , the x-intercept will be 5 , y-intercept will be 4 and the coordinate will be (x , y) = (5 , 4).

(x - 9) × (x2 + 9x + 81)  = 0

Subtract/Add

x - 9 = 0 = 9

x^2 + 9x = -81

-81 + 81/4

-243/4

x^2 + 9x + (81/4) = -243/4

(x + (9/2)) × (x + (9/2)) = (x + (9/2)) × 2

(x + (9/2))2 = -243/4

x^2 + 9x + 81 = 0

A triangle is congruent, and Range of values for x is 5 < x < 29

According to the figure, if L(AB) is less than L(AD), the ∠ACB must be less than the ∠ACD. Take note of how these angles are opposite to the sides stated.

∴ ∠ACB < ∠ACD

⇒2x-10 < 48

At the same time, 2x-10 > 0.

∴ 0< 2x-10 < 48

The minimum firing time for a stable orbit 300km above Earth is 25 seconds.

An orbit, in the context of celestial mechanics, is the curved path taken by an object, such as the trajectory of a planet around a star, a natural satellite around a planet, or an artificial satellite around an object or place in space, such as a planet, moon, asteroid, or Lagrange point.

Ordinarily, the term "orbit" denotes a trajectory that repeats itself on a regular basis, though it can also denote a non-repeating trajectory. Kepler's rules of planetary motion roughly describe the elliptic orbits that planets and satellites take, with the center of mass orbiting at a focal point of the ellipse.

We know that to achieve stable orbit 300 km above earth, the velocity must be ≈ 7.7 km/s

We will use the given formula

              v = -0.0098 t+c ln R

Here given that c = 2.5 km/s

                          R = 24

Apply the information in the equation we get,

7.7 = -0.0098t + 2.5  In  24

we can also write

t = [tex]\frac{7.7 - 2.5 In 24}{-0.0098}[/tex]  

 = [tex]\frac{7.7 - 7.945}{-0.0098}[/tex]
