If A, B, and C are the vertices of a triangle, find AB + BC + CA.
Answers
Answer:
0Step-by-step explanation:
When drawing a triangle, note that the vectors can be drawn either in a clockwise or anticlockwise direction. For a triangle with vertices A, B and C, te vectors are AB, BC and CA
In vector notation CA = - AC (length CA is equal to AC but acting in opposite direction to AC)
and AB+BC = AC
To evaluate AB + BC + CA, we will substitute the vector expression above into the given expression and simplify as shown;
= (AB + BC) + CA
= AC + (-AC)
open the parenthesis
= AC-AC
= 0
Hence the sum of the vector expression AB + BC + CA is a zero vector

Answers
Answer:
-4=x
Step-by-step explanation:
Okay, let's do this step-by-step for the best results!
We need to make sure that common variables can be put together first. If you did not know this, look at PEMDAS.
-x+7=-6x-13
We need to add -x and -6x together. If we do that then you would get,
7=-5x-13
Let's add 13 to 7 now.

A ranger in a lookout tower spots two fires on the campground below. Fire A is 75 meters east
and 40 meters south of the tower. Fire B is 37 meters west and 64 meters south of the tower.
If there is a fire hydrant located three-fourths of the way from Fire A to Fire B, find the location
of the fire hydrant relative to the tower.
Answers
Answer:
the fire hydrant is 9 meters west and 58 m south of the tower
Step-by-step explanation:
Fire A and Fire B can be represented as a point in the Cartesian coordinate with the tower as the origin. Fire A is 75 meters east and 40 meters south of the tower, It can be represented as (75, -40). Fire B is 37 meters west and 64 meters south of the tower, It can be represented as (-37, -64).
If a point O(x, y) divides a line segment AB in the ratio n:m, with A([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2[/tex]), the point O(x, y) is at:
[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1\\ \\y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]
The fire hydrant (x, y) divides Fire A(75, -40) and fire B(-37, -64) in the ratio 3:1(three fourth), hence:
[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1=\frac{3}{4}(-37-75) +75=\frac{3}{4}(-112)+75=-84+75\\x=-9 \\ \\y=\frac{n}{n+m}(y_2-y_1)+y_1=\frac{3}{4}(-64-(-40))+(-40)= \frac{3}{4}(-18)-40=-18-40\\y=-58[/tex]
The fire hydrant is at (-9, -58). That is the fire hydrant is 9 meters west and 58 m south of the tower
The location of the hydrant relative to the tower is [tex]\left(-9, -58 \right)[/tex] meters.
How to locate the coordinates of the hydrant relative to the towerIn this question we should use the vectorial formula for a line segment to determine the coordinates of the hydrant relative to the tower ([tex]\vec C[/tex]), in meters:
[tex]\vec C = \vec A + r\cdot (\vec B - \vec A)[/tex] (1)
Where:
[tex]\vec A[/tex] - Coordinates of the fire A relative to the tower, in meters. [tex]\vec B[/tex] - Coordinates of the fire B relative to the tower, in meters. [tex]r[/tex] - Distance ratio.Now we determine the location of the hydrant: ([tex]\vec A = (75, -40)\,[m][/tex], [tex]\vec B = (-37, -64)\,[m][/tex], [tex]r = \frac{3}{4}[/tex])
[tex]\vec C = (75,-40) + \frac{3}{4}\cdot [(-37,-64)-(75,-40)][/tex]
[tex]\vec C = (75,-40) + \frac{3}{4} \cdot (-112,-24)[/tex]
[tex]\vec C = (75,-40) + \left(-84, -18\right)[/tex]
[tex]\vec C = \left(-9, -58 \right)\,[m][/tex]
The location of the hydrant relative to the tower is [tex]\left(-9, -58 \right)[/tex] meters. [tex]\blacksquare[/tex]

Se tiene un conjunto de triángulos equiláteros, cuya medida de lados están en progresión geométrica cuya razón es 2. Si se ordenan los triángulos de acuerdo a su tamaño, se tiene que el primer triángulo mide un 1 cm de lado , ¿cuánto medirá el lado del vigésimo triángulo equilátero?¿cuánto medirá su perímetro?
Answers
Responder:
Explicación paso a paso:
Dado el conjunto de un triángulo equilátero con cada uno de sus lados en progresión geométrica, si el primer triángulo mide un lado de 1 cm y una razón común de 2 cm, para obtener el lado del triángulo 29, usaremos la fórmula para calcular el enésimo término de la progresión geométrica. expresado como;
Tn = ar ^ (n-1)
a es el primer término
n es el número de términos
r es la razón común.
Dados los siguientes parámetros
a = 1, r = 2 y n = 20 (ya que estamos buscando el lado del vigésimo triángulo)
Sustituyendo los parámetros dados en la fórmula para obtener el lado del triángulo 20, tendremos;
T20 = 1 (2) ^ 20-1
T20 = 1 (2) ^ 19
T20 = 2 ^ 19
T20 = 524,288 cm
Por lo tanto, la medida de la longitud de un lado del vigésimo triángulo equilátero es 524,288 cm.
Perímetro del vigésimo triángulo equilátero = 3 × 524,288 = 1,572,864cm
Tenga en cuenta que todos los lados de un triángulo equilátero son iguales.

Maya runs 7 miles in 80 minutes. At the same rate, how many miles would she run in 64 minutes?
Answers
Answer:
5.6 miles.
Step-by-step explanation:
7/80=x/64 is our equation
Cross multiply to solve for x
x=7*64/80
x=5.6mi
Hope this helps ^-^
Answer:
5.6 miles
Step-by-step explanation:
Let's set up a proportion using the following setup.
[tex]\frac{miles }{minutes}=\frac{miles }{minutes}[/tex]
We know Maya can run 7 miles in 80 minutes.
[tex]\frac{7miles }{80minutes}=\frac{miles }{minutes}[/tex]
We don't know how many miles she can run in 64 minutes. Let's say she can run x miles in 64 minutes.
[tex]\frac{7miles }{80minutes}=\frac{x miles }{64 minutes}[/tex]
[tex]\frac{7}{80}=\frac{x}{64}[/tex]
We want to solve for x (miles in 64 minutes). Therefore, we must isolate x on one side of the equation.
x is being divided by 64. The inverse of division is multiplication. Multiply both sides of the equation by 64.
[tex]64*\frac{7}{80}=\frac{x}{64}*64[/tex]
[tex]64*\frac{7}{80}=x[/tex]
[tex]64*0.0875=x[/tex]
[tex]5.6=x[/tex]
[tex]x= 5.6 miles[/tex]
Maya can run 5.6 miles in 64 minutes.

7−y
The equation solved for y is y=7-2x.
The given equation is 2x+y=7.
We need to solve the given equation for y.
How to solve an equation?Solving equations is computing the value of the unknown variable still balancing the equation on both sides. An equation is a condition on a variable such that two expressions in the variable have equal value. The value of the variable for which the equation is satisfied is said to be the solution of the equation. An equation remains the same if the LHS and the RHS are interchanged.
Now, solving the equation for y, we get y=7-2x.
Put x=1, 2, 3, 4,....in the equation and find the y value.
So, put x=1 in equation y=7-2(1)=5.
Put x=2, we get
y=7-2(2)=3
Verification: Put the ordered pair (1, 5) in the equation and verify.
That is, 5=7-2(1)
⇒5=5
Therefore, the equation solved for y is y=7-2x.

The length of a rectangle is four meters less than twice it's width. If the area of the rectangle is 96 square meters what is the width?
Answers
Answer: (I'm sorry if this is not the right answer)
The width = 8 meters
Step-by-step explanation:
The length: a (m)
The width: b (m)
We cannot have a negative length and a negative width: a>b>0
Eq. I: a=2b-4
Eq. II: ab=96
Substitute the value of a from Eq. I into Eq. II: (2b-4).b=96
Solve for b:
(2b-4).b=96
2[tex]b^{2}[/tex]-4b-96=0
[tex]b^{2}[/tex]-2b-48=0
[tex]b^{2}[/tex]+6b-8b-48=0
b.(b+6)-8.(b+6)=0
(b+6).(b-8)=0
b=8; b=-6
As mentioned above, b>0. Therefore, b=8
Conclusion: if the area of the rectangle is 96 square meters then its width is 8 meters.
The width of the given rectangle is 8 units.
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Perimeter of rectangle = 2( length + width).
Let's say the length of the rectangle is L and the width is W
Given that,
The length of a rectangle is four meters less than twice its width.
So,
L = 2W - 4
And,
Area = 96 square meter
LW = 96
Now by substituting
2W² - 4W = 96
W² - 2W - 48 = 0
W² -8W + 6W - 48 = 0
W(W - 8) + 6(W - 8) = 0
(W + 6)(W - 8) = 0
W = 8, -6 since distance cannot be negative so it will be 6 meters.
Hence "The width of the given rectangle is 8 units".
