The value of r such that the slope associated with two points (12, 10), (-2, r) is -4 is 66.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
Given two points,
(12, 10) , (-2, r)
The slope associated with (x₁, y₁) and (x₂, y₂) →
Slope(m) = (y₂ - y₁)/(x₂ - x₁)
So,
m = (r - 10)/(-2-12)
(r - 10)/(-14) = -4
r - 10 = 56
r = 66
Hence "The value of r such that the slope associated with two points (12, 10), (-2, r) is -4 is 66".

What is the length of TW
Answer:
32 units.
Step-by-step explanation:
We have been given a graph of a line segment and we are asked to find the length of line segment TW.
Upon looking at our graph we can see that point U divides segment TW in two equal parts (TU and UW), which means that length of TW will be two times the length of TU or UW.
We have been given the length of TU is 16 units. To find the length of segment TW we will multiply 16 by 2.
[tex]\text{Length of TW}=2\times 16=32[/tex]
Therefore, the length of line segment TW will be 32 units.

Can anyone solve this problem???
One person can complete a typing project in 6 hours, and another can complete the same project in 8 hours. How long will it take the two people working together to complete the project???
Time taken to complete the project if two people worked together is required.
It would taken around 3.4 hours to complete the project if both the people worked together
Time taken to complete the work by first person is 6 hours
Time taken to complete the work by second person is 8 hours
The work equation will be be
[tex]\dfrac{1}{6}+\dfrac{1}{8}=\dfrac{1}{x}\\\Rightarrow \dfrac{4+3}{24}=\dfrac{1}{x}\\\Rightarrow x=\dfrac{24}{7}\approx 3.4\ \text{hours}[/tex]

What common angle do CDG AND FCE share?
FBG is congruent to DBE
CEF is congruent to CGD
CDG is congruent to CFE
GCE is congruent to ECG
Answer:
The correct option is 4.
Step-by-step explanation:
From the given figure it is noticed that the triangle CDG and triangle FCE have a common vertex C. So both triangle are sharing same angle at vertex C.
In triangle CDG and triangle FCE
[tex]\angle GCD\cong \angle FCE[/tex]
If the length of two adjacent sides increases, then the inclined angle remains the same.
If the side CD increased to E and side CF increased to G, then
[tex]\angle GCE\cong \angle ECG[/tex]
Therefore option 4 is correct.

Therefore option A is true because [tex]\frac{11}{3}>3[/tex] Spring league is increasing more than twice as fast as fall league.
B). This option is not true because participation in the spring league is increasing nearly 4 times of Fall league.
C) False. Spring league participation is more than fall league.
D) False. Same as option C because spring league participation is more than fall league.
How to find components of a vector given magnitude and angle?
The components of the vector in rectangular form given magnitude and angle can be found by using the following formulas: [tex]x = \|\vec r\|\cdot \cos \theta[/tex], [tex]y = \|\vec r\| \cdot \sin \theta[/tex].
How to determine the magnitude and angle of a vector
Let be a vector in rectangular form, that is, a vector of the form (x, y). The magnitude can be found by applying the square root of the dot product of the vector or the Pythagorean theorem and the direction is determined by applying inverse trigonometric functions:
Magnitude (linear algebra approach)[tex]\|\vec r\| = \sqrt{(x,y)\,\bullet\,(x,y)}[/tex] (1)
Magnitude (algebra approach)[tex]\|\vec r \| = \sqrt{x^{2}+y^{2}}[/tex] (2)
Directionθ = tan⁻¹ (y/x) (3)
And the components of the vector can be found by applying the following formulas:
[tex]x = \|\vec r\|\cdot \cos \theta[/tex] (4)
[tex]y = \|\vec r\| \cdot \sin \theta[/tex] (5)

You can find the components of a vector given its magnitude and angle by using the cosine function to find the horizontal component, and the sine function to find the vertical component.
Explanation:To find the components of a vector given its magnitude and angle, you will use basic trigonometric ratio principles. These principles typically involve the use of sine (sin) and cosine (cos) functions.
First, consider a vector V with magnitude (or length) denoted by |V| and an angle θ from the positive x-axis. The components of the vector can be resolved into horizontal (x-direction) and vertical (y-direction) components.
The x-component (Vx) of the vector can be found using the equation:
Vx = |V| cos(θ).
Similarly, the y-component (Vy) of the vector can be found using the equation:
Vy = |V| sin(θ).
These equations are derived from the definitions of the sine and cosine functions in a right triangle, which is formed by the vector V and its components.
