The length of the radius DC (or EC) in units is 20 units and the coordinates of the center C of the circle is (19, 17) using concept of Coordinate Geometry and Lines.

As per the question statement, The diameter of a circle has endpoints D(7, 33) and E(31, 1). The center of the circle denoted by C, is the midpoint of the diameter. We are supposed to find the length of the radius DC (or EC) in units and the coordinates of the center C of the circle

Now using the distance formula in Line concept and coordinate geometry,

Distance between two points is given by d = √{(x2-x1)^2+(y2-y1)^2}

Given coordinates of D are (7, 33) and E are (31, 1)

Therefore Distance DE = √{(31-7)^2 + (1-33)^2}

DE = √{(576)+(1024)}

DE = √1600

DE = 40 units

Therefore, length of diameter DE is 40 units so length of radius DC (or EC)  will DE/2 = 40/2 = 20 units

Now using Mid Point Formula of  Line concept and coordinate geometry,

Mid Point of line joining two points is given by

C = ({x1 + x2}/2, {y1 + y2}/2)

C = ( {31+7}/2 , {1+33}/2)

C = (19, 17)

Answer:

Linear pair of angles are formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°. Such angles are also known as supplementary angles.

Step-by-step explanation:

If there is a pair of adjacent angles, then this pair is a linear pair if the sum of the (measures of the) two angles will be 180°. So, linear pair of angles always add up to 180°. For example, the linear pair of 30° is 150°, the linear pair of 70° is 110°, etc.

These two angles form a linear pair. We have found all four linear pairs of angles. The four linear pairs formed by the intersecting lines ←→QR Q R ↔ and ←→ST S T ↔ are ∠SOQ ∠ S O Q and ∠QOT ∠ Q O T , ∠QOT ∠ Q O T and ∠TOR ∠ T O R , ∠TOR ∠ T O R and ∠ROS ∠ R O S , and ∠ROS ∠ R O S and ∠SOQ ∠ S O Q .

Answer:

x = -6.36

Step-by-step explanation:

(18 + x) × 28 = 326

Divide both sides by 28

18 + x = 11.64

Subtract 18 from both sides

x = -6.36

The angle made by the vector is [tex]\theta[/tex] such that

[tex]\tan(\theta) = \dfrac{18.4\,\rm m}{-28.7\,\rm m} \approx -0.6411[/tex]

Before taking the inverse tangent of both sides, recall that [tex]\arctan[/tex] returns a number between -π/2 and π/2 radians, or -90° and +90°. The vector in the diagram clearly makes an angle between 90° and 180°, however, so we use the fact that tangent has a period of π rad / 180° to write

[tex]\theta \approx \arctan(-0.6411) + 180^\circ n[/tex]

where [tex]n\in\Bbb Z[/tex].

Now,

[tex]\arctan(-0.6411) \approx -0.5701 \,\mathrm{rad} \approx -32.6639^\circ[/tex]

Add 180° to this to recover the correct angle.

[tex]\theta = \arctan(-0.6411) + 180^\circ \approx \boxed{147.34^\circ}[/tex]

According to the graph,

Let y = [tex]{m_1}[/tex]x + [tex]b_1[/tex] [[tex]b_1[/tex] = 2]

when x = -2 , y = 0

-2[tex]m_1[/tex] + 2 = 0 [[tex]{m_1}[/tex] = 1]

→ So when x ≤ 2 , y = x + 2

Let y = [tex]m_2[/tex]x + [tex]b_2[/tex]

[tex]m_2 = \frac{4 - 3}{3 - 2} = 1 \: \: \: \: \: \: \: \: \: \: [m = \frac{y_2 - y_1}{x_2 - x_1} ][/tex]

when x = 2 , y = 3

3 = 2 × 1 + [tex]b_2[/tex] , [tex]b_2[/tex] = 1

→ So when x > 2 , y = x + 1

[tex]y =\begin{cases}x + 1 \: \: \: \: \: \: \: \: x >2\\x + 2 \: \: \: \: \: \: \: \: x \leqslant 2\end{cases}[/tex]

The missing angles of the Triangle are; ∠1 = 62°; ∠2 = 45° and ∠3 = 22°.

We know that the sum of angles on a straight line is 180 degrees. Thus, we can say that;

∠1 + 118° = 180°

∠1  = 180 - 118

∠1 = 62°

We also know that sum of angles in a triangle is equal to 180°. Thus;

∠1 + ∠2  + 73 = 180

Plugging in the relevant value gives;

62 + ∠2  + 73 = 180

∠2 = 180 - 135

∠2 = 45°

∠2 + ∠3 = 180 - (∠1 + 49)

∠2 + ∠3 = 180 - (62 + 49)

45° + ∠3 = 69

∠3 = 22°

Thus, we conclude that the missing angles of the Triangle are; ∠1 = 62°; ∠2 = 45° and ∠3 = 22°.

Step-by-step explanation:

what did your teacher do in class ? nothing ?

it is really not that complicated :

the slope of a line is the ratio (y coordinate change / x coordinate change) when going from one point on the line to another.

it tells us how many units y changes when x changes by a certain number of units.

e.g. a slope of 2 = 2/1 means that when we increase x by 1, y increases by 2.

a positive slope means that the line goes up (seen while going from left to right).

a negative slope means that the line goes down.

therefore, a slope of 0 means a flat, horizontal line.

while for a vertical line the slope is the result of a division by 0 and is therefore undefined (some like to symbolize this by infinity).

parallel simply means to have the same slope. parallel lines imitate each other's behavior and attributes perfectly except for the absolute physical location.

perpendicular (at a 90° angle) slopes now simply turn x and y in the ratio upside-down and flip the overall sign of the slope.

e.g. the perpendicular slope of 2 = 2/1 is -1/2.

oh, and the slope of a function or curve that is not a line ?

then we go point by point, as the function does not have one slope for everything. and the slope of the function at a particular point is the slope of the tangent line at that point.

We select equation B :
Equation B is : 40 divided by c = 2 times 5

We can write,

Equation B is : 40/c = 2x5

simplify equation,

 40 players / c = 2 teams x 5 players

We can write,

                             40/c = 2x5

                              40/c = 10

                              40 = 10c
