Answer:

12

Step-by-step explanation:

20-6=14 (Distance between points) then 14*3/7=6.

3/7 of the distance from A=6 to B=20 is 6. Thus, we find the point that is

3/7 of the distance from A=6 to B=20 by adding 6 to 6.

6+6= 12

Therefore, the point that is

3/7 from A=6 to B=20 is 12.

Here :

Solving

Answer:

[tex]274\ units^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of top and bottom

[tex]A = l * w[/tex]

[tex]A = 13\ units * 4\ units[/tex]

[tex]A = 52\ units^2[/tex]

Top and bottom gives us (52 units^2 * 2) = 104 units^2

Step 2:  Determine the area of the sides

[tex]A = l * w[/tex]

[tex]A = 4\ units * 5\ units[/tex]

[tex]A = 20\ units^2[/tex]

Sides gives us (20 units^2 * 2) = 40 units^2

Step 3:  Determine the area of the front and back

[tex]A = l * w[/tex]

[tex]A = 13\ units * 5\ units[/tex]

[tex]A = 65\ units^2[/tex]

Ffront and back gives us (65 units^2 * 2) = 130 units^2

Step 4:  Add up the areas to get the total surface area

[tex]104\ units^2 + 40\ units^2 + 130\ units^2[/tex]

[tex]274\ units^2[/tex]

Answer:  [tex]274\ units^2[/tex]

The required area of a sector with an arc of 40 cm and a radius of 12 cm is given as 240 cm².

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,
Sectoral area = arc / 2 × radius
Sectoral area = 40 / 2 × 12

                    = 20 × 12 = 240 cm²

Thus, the required area of a sector with an arc of 40 cm and a radius of 12 cm is given as 240 cm².

Answer:

y = (x-5)² - 3

Step-by-step explanation:

Given:

Answer:

  (b) 7.28 cis(105.945°)

Step-by-step explanation:

The trig form of a vector is always ...

  magnitude(cos(angle)·i +sin(angle)·j)

Sometimes, that is abbreviated ...

  magnitude cis(angle)  or  magnitude∠angle

where the "angle" is measured counterclockwise from the +x axis.

__

The forms showin in choices C and D can be rejected immediately because the sine and cosine coefficients are incorrectly placed. To differentiate between choices A and B, you need to know whether the angle is greater than 90°. The terminal point is above and left of the initial point, so the angle must be more than 90°. (It can help to plot the points on a graph.)

  u = 7.28(cos 105.945°i + sin 105.945°j)

Answer:

Step-by-step explanation:

A bearing is measured clockwise from north. To do this measurement, we need to extend the line beteen A and B and extend the North-pointing line so they cross.* A protractor or other measuring tool is then used to measure the angle between the lines.

__

In the attached, we have found the angle between these lines to be about 29°. This is the angle between north and B, as seen from A.

  29° = bearing of B from A

__

As seen from B, the angle is 180° more than the one of B from A. The bearing of A from B is ...

  180° +29° = 209° . . . . . bearing of A from B

_____

* The angle measurement can be made between any set of lines that are coincident with or parallel to the north line and the line between A and B. In the attached, we attempted to maximize accuracy by using the lines on the figure, rather than creating parallel lines for the purpose of the measurement.

On a figure such as this, it is very difficult to get accuracy to even 0.1 degrees. For example, the geometry program that we used says the slope of the AB line is tangent(60.58°), so the bearing using that information is about 29.42°, not the 29.29° the same program reports as the measurement of the angle.

We don't have access to your original figure, and we can't account for any distortions that may have occurred in the copying and pasting of the image. Straight dilation will not change the angle, but most image reproduction processes have different scale factors in different directions, which will affect the angle measurement. YMMV

Step-by-step explanation:

Answer:

Left to right, (26,100,50,41)

Step-by-step explanation:

a^2 + b^2 = c^2

100+576=676, sq root is 26

3600+6400=10,000, sq root is 100

900+1600=2500, sq root is 50

1600+81=1681, sq root is 41.

You square a and b, you add them together to get c squared. You then take the square root of c squared to get c.

Answer:

(0,0)

Step-by-step explanation:

a diameter means The average of two measurements of the diameter taken at right angles to each other. so if you try graphing you will be able to find out its (0,0) is the center of the circle coordinates

The coordinates of the center of this circle is (0,0).

The center of a circle is the midpoint of the diameter. So, by using the midpoint formula, if the endpoints of the diameter are (a, b) and (c, d), then the coordinates of the center of circle are [(a + c)/2, (b + d)/2].

According to the question

The endpoints of the diameter of a circle are (6, 0) and (-6, 0).

now ,

(a,b) =  (6, 0)

(c, d)= (-6, 0)

coordinates of the center of circle = [ [tex]\frac{a+c}{2} ,\frac{b+d}{2}[/tex] ]

⇒ [tex]\frac{6-6}{2} ,\frac{0+0}{2}[/tex]

⇒ (0,0)

Hence, the coordinates of the center of this circle is (0,0).
