When ax3+bx-6 is divided by x+3,the remainder is 9. Find term of a only . The remainder when 2x3-bx2+2ax-4 when it is divided by x-2
Answer:
a) a = - ( 5 + b ) / 9
b) no remainder
Step-by-step explanation:
A) ( ax^3 + bx -6 ) / ( x + 3 )
Remainder = 9
determine the value of a
we will use the result of if ( x + a ) divides polynomial g(x) the remainder is g(a)
therefore given that ( x + 3 ) divides f(x) = ax^3 + bx - 6
= f( -3 ) = 9
= a(- 27 ) - 3b - 6 = 9
= -27a = 9 + 6 + 3b
therefore the term 'a' = - ( 15 / 27 + 3b / 27 )
= - ( 5/9 + b/9 )
a = - ( 5 + b ) / 9
b) Find the remainder when (2x^3 - bx^2 + 2ax - 4 ) is divided by (x-2 )
given that ( x -2 ) divides f(x) = 2x^3 - bx^2 + 2ax - 4
also given a = - ( 5 + b ) / 9 from previous polynomial above
= f(2) = ?
= 2(8) -4b + 4a - 4
= 16 - 4b + 4 ( - ( 5 + b ) / 9 ) - 4
= 16 - 4b + (( -20 - 4b ) / 9) - 4
= 16 - 4b - ( 20 - 4b ) / 9) - 4
= 16 - ( 32b - 20 ) / 9) - 4 = ?
therefore the remainder 'b' = ( -108 + 20 ) / 32 = - 2 3/4
since the remainder is negative there is no remainder then

Hakan is standing next to a building whose shadow is 15 feet long. If Hakan is 6 feet tall and is casting a shadow 2.5 feet long, how high is the building?
Height of Building = Feet
answer:
Answer:
36 feet long
Step-by-step explanation:
When you get the question it should look like this: 6/2.5 X/15.
Your gonna have to cross multiply 6 and 15 the keep 2.5 and X like this: 2.5x
After that, it should look like this: 2.5x=90, Now your gonna wanna divide 90 and 2.5 which you will get 36.
X= 36 ft long.

Una fábrica produce tres tipos de balones de fútbol, con un costo mensual de
$24,250.00 por cada 1125 balones. Los costos de fabricación son $ 40.00, $ 30.00 y $
20.00. Estos balones se venden en $ 160.00, $ 120.00 y $ 100.00, respectivamente.
¿Cuántos balones de cada tipo se fabrican si la ganancia mensual es de $ 92,750.00?
Answer:
Se fabricaron:
1000 balones de los que cuestan $20
75 balones de los que cuestan $30
50 balones de los que cuestan $40
Step-by-step explanation:
Vamos a definir las variables:
x = número de balones de $100.00 vendidos.
y = número de balones de $120.00 vendidos
z = número de balones de $160,00 vendidos.
Sabemos que se producen 1125 balones, entonces:
x + y + z = 1125
y el costo de producción es $24,250, conociendo el costo de cada balón podemos escribir:
x*$20 + y*$30 + z*$40 = $24,250
Y también sabemos que la ganancia mensual es $92,750
Ganancia es la diferencia entre el dinero total recibido y los costos, entonces:
x*$100 + y*$120 + z*$160 - $24,250 = $92,750
x*$100 + y*$120 + z*$160 = $92,750 + $24,250
x*$100 + y*$120 + z*$160 = $117,000
Entonces tenemos un sistema de 3 ecuaciones:
x + y + z = 1125
x*$20 + y*$30 + z*$40 = $24,250
x*$100 + y*$120 + z*$160 = $117,000
Para resolver esto debemos comenzar por aislar alguna variable en alguna de las ecuaciones, yo comenzare aislando x en la primera ecuación:
x = 1125 - y - z
Ahora podemos reemplazar esto en las otras dos ecuaciones para obtener:
(1125 - y - z)*$20 + y*$30 + z*$40 = $24,250
(1125 - y - z)*$100 + y*$120 + z*$160 = $117,000
Si simplificamos esto obtenemos:
$22,500 + y*$10 + z*$20 = $24,250
$112,500 + y*$20 + z*$60 = $117,000
Ahora de vuelta, debemos aislar una variable en una de las ecuaciones, si aislamos y en la primera ecuación obtenemos:
y*$10 = $24,250 - $22,500 - z*$20
y = ($1,750 - z*$20)/$10
y = 175 - 2*z
Reemplazando esto en la otra ecuación obtenemos:
$112,500 + (175 - 2*z)*$20 + z*$60 = $117,000
Ahora podemos resolver esto para z.
(175 - 2*z)*$20 + z*$60 = $117,000 - $112,500
(175 - 2*z)*$20 + z*$60 = $4,500
$3,500 - z*$40 + z*$60 = $4,500
$3,500 + z*$20 = $4,500
z*$20 = $4,500 - $3,500 = $1,000
z = $1,000/$20 = 50
Entonces tenemos 50 balones de los que cuestan $40.
Usando la ecuación y = 175 - 2*z podemos encontrar el valor de y.
y = 175 - 2*50 = 75
Entonces tenemos 75 balones de los que cuestan $30.
Usando la ecuación x = 1125 - y - z podemos encontrar el valor de x.
x = 1125 - 75 - 50 = 1000
tenemos 1000 balones de $20.

Answer:
Para saber el puntaje máximo que obtuvo el 75% de los alumnos se debe calcular el tercer cuartil.
Step-by-step explanation:
Los Cuantiles (cuartiles, deciles, percentiles) son medidas de localización cuya función es informar del valor de la variable que ocupará la posición (en tanto por cien) que interese respecto de todo el conjunto de variables.
Los cuartiles son medidas estadísticas de posición que tienen la propiedad de dividir la serie estadística en cuatro grupos de números iguales de términos.
El primer cuartil o cuartil inferior es aquel valor de la variable tal que la cuarta parte (25%) de las observaciones son inferiores o iguales a él, y el resto (75%) es superior o igual. El segundo cuartil es la mediana, ya que se trata del valor localizado en la mitad de la distribución. Finalmente, el tercer cuartil o cuartil superior es un valor tal que las tres cuartas partes de las observaciones son inferiores o iguales a él.
En otras palabras, el primer cuartil Q1, es el valor en el cual o por debajo del cual queda aproximadamente un cuarto (25%) de todos los valores de la sucesión (ordenada); El segundo cuartil Q2 es el valor por debajo del cual queda el 50% de los datos (Mediana), el tercer cuartil Q3 es el valor por debajo del cual quedan las tres cuartas partes (75%) de los datos. Es decir, Q1, Q2 y Q3 determinan los valores correspondientes al 25%, al 50% y al 75% de los datos respectivamente. Q2 coincide con la mediana.
Para saber el puntaje máximo que obtuvo el 75% de los alumnos se debe calcular el tercer cuartil.
a triangle where one angle 120 degrees and another 50 degrees
I do not understand what you are asking for
I am assuming you want the missing angle, in this case it is 10
Triangle Sum Theorem states that a triangle is equal to 180 degrees
120+50 = 170
180-170

Step-by-step explanation:
What is the height of a cone with a slant height of 16 inches and a radius of 6 inches? Round your answer to the nearest whole number.
Answer:
14.8 inches
Step-by-step explanation:
Given that:
Slant height, l = 16 inches
Radius, r =. 6 inches
Using the relation :
h² + r² = l²
h² + 6² = 16²
h² = 16² - 6²
h² = 256 - 36
h² = 220
h = sqrt(220)
h = 14.832
h = 14.8 inches

Bob bought a broken motor scooter, repaired it, and sold the scooter for $130. That was $50 less than 1.5 times what he paid for it.
Answer: $120
Step-by-step explanation:
Assume the original price is x.
He sold the scooter for $130 and this was $50 less than 1.5 times what he paid for it.
Relevant formula is therefore:
1.5x - 50 = 130
1.5x = 130 + 50
x = 180/1.5
x = $120
Write the equation in slope-intercept form for each line based on the information given.
The line has a slope of -1 and goes through the point (2,4).
Answer:
y = -1x + 6 or y = -x + 6
Step-by-step explanation:
First, let's identify what slope-intercept form is.
y = mx + b
m is the slope. b is the y-intercept.
We know the slope is -1, so m = -1. Plug this into our standard equation.
y = -1x + b
To find b, we want to plug in a value that we know is on this line: (2, 4). Plug in the x and y values into the x and y of the standard equation.
4 = -1(2) + b
To find b, multiply the slope and the input of x(2)
4 = -2 + b
Now, add 2 from both sides to isolate b.
6 = b
Plug this into your standard equation.
y = -1x + 6
This is your equation.
Check this by plugging in the point again.
y = -1x + 6
4 = -1(2) + 6
4 = -2 + 6
4 = 4
Your equation is correct.
Hope this helps!
