Answer:

(x+11)² + (y-3)² = 121

Step-by-step explanation:

Let us assume we are given the following

Centre of a circle: (-11, 3)

Radius:  11

The standard equation of a circle is expressed as;

(x-a)² + (y-b)² = r²

(a, b) is the centre

r is the radius

a = -11, b = 3 and r  = 11

Substitute

(x-(-11))² + (y-3)² = 11²

(x+11)² + (y-3)² = 121

Hence the required equation of the circle is (x+11)² + (y-3)² = 121

Note that the centre and the radius of the circle was assumed

Step-by-step explanation:

you really need help with that ? it is all already given in the problem description. you only need to do the 6 little calculations (anyways adding 6). what is the problem ?

a1 = 7

a2 = a1 + 6 = well ? ... ... ... 13, of course

a3 = a2 + 6 = 13 + 6 = weeeeelllll ?

a4 = a3 + 6 = 13 + 6 + 6 = weeeellll ?

a5 = a4 + 6 = 13 + 6 + 6 + 6 =

a6 = a5 + 6 = 13 + 6 + 6 + 6 + 6 =

I am really not doing your very basic and just "mechanical" work of doing simple calculations in your head or on your calculator.

I help you, when you have a problem understanding the issue, but not when you ask me to do your pure "mechanical" job that every elementary school student can do easily.

to help with the understanding, such a sequence (using this example) can then be described and every element calculated by

a(n) = a(1) + 6*(n-1)

so, for example

a20 = 7 + 6*19 = 121

so, and now that you truly understand the concept, just use your calculator (if you truly cannot do that in your head) and do your job.

Answer:

53 meters

Step-by-step explanation:

The angle between a viewer's horizontal line of sight and the line of sight down towards a particle is called the angle of depression. For example if a viewer is sitting at the top of a tower and looking down on a car, the angle between the viewer's horizontal line of sight and the line of sight to which he looks at the car is the angle of depression.

A sketch of the positions of the boats and the tower has been attached to this response.

As shown,

the distance between the two boats A and B is marked x meters.

the horizontal distance between boat A and the foot of the tower is y meters.

the horizontal distance between boat A and the foot of the tower is  x + y meters.

the height of the tower is 60 meters.

the angle of depression of boat A is 28°

the angle of depression of boat B is 45°

To find the value of y, from triangle DBC we use the trigonometric ratio for tangent. i.e

tan 45° = [tex]\frac{60}{y}[/tex]

1 = [tex]\frac{60}{y}[/tex]

y = 60 meters

To find the value of x, from triangle ABC we use the trigonometric ratio for tangent. i.e

tan 28° = [tex]\frac{60}{x+y}[/tex]

Where y = 60 meters

tan 28° = [tex]\frac{60}{x+60}[/tex]

0.5317 = [tex]\frac{60}{x+60}[/tex]

x + 60 = [tex]\frac{60}{0.5317}[/tex]

x + 60 = 112.85

x = 112.85 - 60

x = 52.85 meters

Therefore, boat A is about 53 meters from boat B

Answer:

C

Step-by-step explanation:

Answer:

5 = y

7.1 = x

Step-by-step explanation:

(There are so many ways we can solve this, let's solve this the easiest way):

Let's solve for y first =

We can say;

Tan(45) = y/5

Tan(45) * 5 = y

1 * 5 = y

5 = y

Now let's solve for x;

5² + y² = x²

5² + 5² = x²

25 + 25 = x²

50 = x²

[tex]\sqrt{50\\}[/tex] = x

7.1 = x

Hope this helps!

Answer:

Y=5 x=50

Step-by-step explanation:

Okay, I'm gonna name this triangle XYZ.

An isosceles triangle is when two sides are equal. We know that an area of a triangle is always 180 degrees. A right triangle always has one degree of 90 degrees. We know that y∠45, x∠90, so z has to be 45 as well.  We know this is a right isosceles triangle due to the angles it has given us.

Now, we know y and z are the same sizes. y=z

using the Pythagorean theorem

D. 90°

90°

All four inner angles of a square are the same (each being 360°/4 = 90°, a right angle). The central angle of a square is equal to 90° (360°/4). The external angle of a square is equal to 90°.

the total interior angles of a square are 360°.

The sum of exterior angles in a polygon is usually equal to 360 degrees. therefore, for all equiangular polygons, the degree of one outdoors perspective is equal to 360 divided by the number of sides in the polygon.

Answer:

Salario reducido= $2.880

Step-by-step explanation:

Dada la siguiente información:

Salario semanal= $3200

Porcentage de reducción= 10%

Para calcular el salario que recibira injustamente María, debemos usar la siguiente formula:

Salario reducido= salario semanal* (1 - porcentage de reducción)

Salario reducido= 3.200*0,9

Salario reducido= $2.880
