ANSWER
GIVEN:
OA= 3x-1 , OC= 5x-3, OD= 6x-5 , BO = 2x+1
AO/OC = BO/OD
[The diagonals of a Trapezium divide each other proportionally]
(3x-1)/(5x-3) =( 2x+1)/(6x-5)
(3x-1) (6x-5) = (5x-3) ( 2x+1)
3x(6x-5) -1 (6x-5) = 2x(5x-3)+1(5x-3)
18x² -15x -6x +5 = 10x² -6x +5x -3
18x² -21x +5 = 10x² - x -3
18x² -10x² -21x + x +5+3 =0
8x² - 20x +8= 0
4(2x² -5x +2) = 0
2x² -5x +2 = 0
2x² -4x -x +2= 0
[By factorization]
2x(x-2) -1(x-2)= 0
(2x-1) (x-2) = 0
(2x-1) = 0 or (x-2) = 0
x = ½ or x = 2
If we put x= ½ in OD , The value of OD is negative.
Hence, the value of is x = 2.

Answer:
1305
Step-by-step explanation:
Equation = [tex]( 5x )^{2} + ( -2x ^{3} )y + ( 3y )^{4}[/tex]
= (5×1)² + {(-2×1)³}×2 + (3×2)⁴
= (5)² + {-2}³×2 + (6)⁴
= 25 + (-8)×2 + 1296
= 25 + (-16) + 1296
= 25 - 16 + 1296
= 9 + 1296

In the figure below, m angle WXZ=113°, and m angle2 is 3° more then m angle1 Find m angle1
Answers
Answer:
m∠1 = 55° ; m∠2 = 58°
Step-by-step explanation:
Let m∠1 = x° , then m∠2 = x° + 3°
m∠1 + m∠2 = 113°
x° + x° + 3° = 113°
2x + 3 = 113
2x = 110
x = 55°
m∠1 = 55° and m∠2 = 58°
The value of m∠[tex]1[/tex] is [tex]55[/tex]° and m∠[tex]2[/tex] is [tex]58[/tex]°
In the given figure m∠WXZ = [tex]113[/tex]° and m∠[tex]2[/tex] is [tex]3[/tex]° more than m∠[tex]1[/tex].
What is angle?
An angle is formed when two rays are joined together at a common point.
Now,
Let m∠[tex]1[/tex] = x° and m∠[tex]2[/tex] = x° + 3°
According to given figure;
m∠[tex]1[/tex] + m∠[tex]2[/tex] = 113°
x° + x° + 3° = 113°
2x° + 3° = 113°
2x° = 110°
x° = 55°
Hence, the value of m∠[tex]1[/tex] = x° = 55° and m∠[tex]2[/tex] = 55° + 3° = 58°

Answer:
f = 8 feet
Step-by-step explanation:
In Δ EBC
∵ DF ⊥ BE
∵ CB ⊥ BE
∴ DF // CB
∵ D is the mid-point of CE
∵ DF // CB
∴ F is the mid-point of EB
∵ DF joining the mid-points of EB and EC
∴ DF = [tex]\frac{1}{2}[/tex] CB
∵ CB = f and DF = 4 ft
∴ 4 = [tex]\frac{1}{2}[/tex] f

Find the m∠ULE in the triangle below.
please
Answers
Answer:
m∠ULE = 60°
Step-by-step explanation:
To find the measure of ∠ULE we will use the property of exterior angle of a triangle.
Since, measure of an exterior angle of a triangle is equal to the sum of two opposite interior angles.
m∠LUR = m∠LEU + m∠ULE
109° = 49° + m∠ULE
m∠ULE = 109 - 49
= 60°
Therefore, measure of angle ULE is 60°.

Harper simplemente encendió una vela nueva y luego la dejó arder hasta la nada. La longitud de la vela que permanece sin quemar, en pulgadas, se puede modelar mediante la ecuación L = 15-1.5t, L = 15−1.5t, donde tt representa el número de horas desde que se encendió la vela. ¿Cuál es la pendiente de la ecuación y cuál es su interpretación en el contexto del problema?
Answers
Answer:
La pendiente de la ecuación es -1.5 y su interpretación en el contexto del problema es que en este caso este valor indica que la longitud L de la vela luego de t horas desde que se encendió la decrece en 1.5 unidades por cada hora.
Step-by-step explanation:
La función lineal se define por la ecuación
f(x) = mx + b
o
y = mx + b
donde m es la pendiente de la recta y b es la ordenada al origen.
La gráfica de una función lineal es siempre una recta.
Como se mencionó, la m es la pendiente de la recta. La pendiente es la inclinación con respecto al eje x, que es el eje de abscisas.
La pendiente m significa que si aumentamos la x en una unidad, la y aumenta en m unidades. Si m es positiva (m > 0), entonces la función es creciente. En cambio, si la m es negativa (m < 0), entonces la función es decreciente.
En este caso, siendo L=1.5 - 1.5t y comparando con la expresión y=mx + b, podes observar que el valor de la pendiente m es -1.5. Como m es un número negativo, entonces se trata de una función decreciente. En este caso este valor de pendiente indica entonces que la longitud L de la vela luego de t horas desde que se encendió la decrece en 1.5 unidades por cada hora.
La pendiente de la ecuación es -1.5 y su interpretación en el contexto del problema es que en este caso este valor indica que la longitud L de la vela luego de t horas desde que se encendió la decrece en 1.5 unidades por cada hora.
