which Equation represents on the passes through (-2,4) and has a slope of 2/5
y-4=2/5(x-2)
y+4=2/5 2/5(x-4)
y+2=2/5(x-4)
y-2=2/5 1/3(x+4)
Step-by-step explanation:
Hey there!
The given point is (-2,4) and slope is 2/5.
While finding the eqaution which has slope and point always use one point formula.
(y-y1) = m(x-x1)
Keep all values.

Alegria va a la tienda a comprar arroz y azucar, pero solo tine 20, si cada libra de arroz cuesta 0.60 y de azucar cuesta 0.80, cuantas libras de cada una le alcanzan para comprar
Answer:
Alegría puede comprar 16.667 libras de arroz y 12.5 libras de azúcar con 20 pesos.
Step-by-step explanation:
Sabemos que una libra de arroz cuesta 0.60 pesos, mientras que una de azúcar cuesta 0.80 pesos. Un enfoque posible es determinar cuantas libras de arroz se obtiene por el mismo dinero para adquirir una libra de azúcar a través de una regla de tres simple:
[tex]x = \frac{0.80\,\$}{0.60\,\$}\times 1\,lb[/tex]
[tex]x = \frac{4}{3}\,lb[/tex]
Esto quiere decir que por cada tres libras de azúcar, se compra cuatro libras de arroz. Ahora, la cantidad de alimentos que puede comprar Alegría queda restringida al dinero disponible (20 pesos) y se describe por la siguiente ecuación:
[tex]0.60\cdot x +0.80\cdot y = 20[/tex] (Ec. 1)
Donde:
[tex]x[/tex] - Cantidad de arroz, medida en libras.
[tex]y[/tex] - Cantidad de azúcar, medida en libras.
Además, la siguiente ecuación se deriva de la regla de tres del inicio del problema:
[tex]x = \frac{4}{3} \cdot y[/tex] (Ec. 2)
Si aplicamos (Ec. 2) en (Ec. 1) y resolvemos la ecuación resultante, tenemos que:
[tex]0.60\cdot \left(\frac{4}{3}\cdot y \right) + 0.80\cdot y = 20[/tex]
[tex]1.60\cdot y = 20[/tex]
[tex]y = 12.5\,lb[/tex]
De (Ec. 2) tenemos que la cantidad de arroz es:
[tex]x = 16.667\,lb[/tex]
En consecuencia, Alegría puede comprar 16.667 libras de arroz y 12.5 libras de azúcar con 20 pesos.
Alegría puede comprar 33.333 libras de arroz o 25 libras de azúcar.
Dado que Alegría va a la tienda a comprar arroz y azúcar, pero solo tiene $20, si cada libra de arroz cuesta $0.60 y de azúcar cuesta $0.80, para determinar cuántas libras de cada una le alcanzan para comprar se debe realizar el siguiente cálculo:
Arroz = 20 / 0.6Arroz = 33.333Azúcar = 20 / 0.8Azúcar = 25Por lo tanto, Alegría puede comprar 33.333 libras de arroz o 25 libras de azúcar.

Natalia estimates that she wins a board game 72% of the time. How large of a random sample is required to obtain a margin of error of at most 0.06 with 95% confidence?
Answer:
Step-by-step explanation:
Margin of error = Z * √p(1-p)/n
z is the z score at 95% confidence = 1.96
p = 0.72
1-p = 0.28
Substitute and get n
Margin of error = Z * √p(1-p)/n
0.06 = 1.96 * √0.72(0.28)/n
0.06/1.96 = √0.72(0.28)/n
0.0306² = 0.2016/n
n = 0.0306²/0.2016
n =0.2016/0.00093636
n = 215.3
Hence the random sample is about 215

Un modelo para la elaboracion de panela tiene forma semiesferica , determina el mayor contenido de miel de caña que puede contener, si se sabe que el perimetro del circulo maximo es 31,4 cm
Answer:
El mayor contenido de miel de caña que puede contener el modelo semiesférico es aproximadamente 261.328 centímetros cúbicos.
Step-by-step explanation:
Sabemos que el volumen del modelo para la elaboración de la panela es directamente proporcional al cubo del radio de la esfera. Dado que el perímetro del círculo máximo ([tex]p_{max}[/tex]), medido en centímetros, es conocido, podemos obtener el radio del modelo según la siguiente fórmula:
[tex]r = \frac{p_{max}}{2\pi}[/tex] (Eq. 1)
Donde [tex]r[/tex] es el radio de la semiesfera, medido en centímetros.
([tex]p_{max} = 31.4\,cm[/tex])
[tex]r = \frac{31.4\,cm}{2\pi}[/tex]
[tex]r \approx 4.997\,cm[/tex]
Ahora, el mayor contenido de miel de caña que puede contenerse en el modelo semiesférico obedece a esta expresión:
[tex]V = \frac{2\pi}{3}\cdot r^{3}[/tex] (Eq. 2)
Donde [tex]V[/tex] es el volumen ocupado por la miel de panela, medido en centímetros cúbicos.
Si conocemos que [tex]r \approx 4.997\,cm[/tex], entonces ese volumen ocupado es:
[tex]V = \frac{2\pi}{3}\cdot (4.997\,cm)^{3}[/tex]
[tex]V\approx 261.328\,cm^{3}[/tex]
El mayor contenido de miel de caña que puede contener el modelo semiesférico es aproximadamente 261.328 centímetros cúbicos.

what is the sum of the first 14 terms of an arithmetic sequence if the 5th term is 31 and the 9th term is 59?
5th term of an AP = 31
9th term = 59
Find:the sum of the first 14 terms of an arithmetic sequence
Solution:We know that,
nth term of an AP – a(n) = a + (n - 1)d
Hence,
⟹ a + (5 - 1)d = 31
⟹ a + 4d = 31 -- equation (1)
Similarly,
⟹ a + (9 - 1)d = 59
⟹ a + 8d = 59 -- equation (2)
Subtract equation (1) from (2).
⟹ a + 8d - ( a + 4d ) = 59 - 31
⟹ a + 8d - a - 4d = 28
⟹ 4d = 28
⟹ d = 28/4
⟹ d = 7
Substitute the value of d in equation (1).
⟹ a + 4(7) = 31
⟹ a + 28 = 31
⟹ a = 31 - 28
⟹ a = 3
Now,
Sum of first n terms of an AP – S(n) = n/2 * [ 2a + (n - 1)d ]
⟹ S(14) = 14/2 * [ 2(3) + (14 - 1)(7) ]
⟹ S(14) = 7 [ 6 + 91 ]
⟹ S(14) = 7 * 97
⟹ S(14) = 679
∴ The sum of first 14 terms of the given AP is 679.
I hope it will help you.

Step-by-step explanation:
Answer:

Step-by-step explanation:
When rounding lets take this problem as an example, you need to rely on the number that is right from it. In this case, it will be the number 3. Any number that is below 4 will be 870,000, any number that is above a 5 will be 880,000. Also note that rounding is always going to be 1-10 not 1-5. What I mean is people will do the mistake and say 873,711 will be rounded to 875,000 which is incorrect.

A pan has an original price of $32 but is marked down by 15 percent. Which equation shows the new price of the pan?
(32 dollars) (100 percent minus 15 percent) = (32 dollars) (85 percent) = 27 dollars and 20 cents
(32 dollars) (15 percent) = 4 dollars and 80 cents
(32 dollars) (15 percent) + 32 dollars = 4 dollars and 80 cents + 32 dollars = 36 dollars and 80 cents
(32 dollars) (185 percent) = 59 dollars and 20 cents

Which equation represents a line which is parallel to the line 4x + 5y=10
The length of a rectangle is 13 meters more than its width. The area of the rectangle is 48 square meters. Determine the length and width of the rectangle. (solve algebraically)
Answer: The length is 16 meters and the width is 3 meters.
Step-by-step explanation:
Since we know the length and w, we will represent the length by l and the width by w.
We know the length is 13 more than the width so we will represent it by the equation l = w + 13 .
The width will be represented by w.
We know the area of a rectangle is the length being multiplied by the width.
Since we know the area, multiply the length by the width and set it equal the area and solve for w.
w(w+ 13) = 48 Multiply on the left side
w^2 + 13w = 48 subtract 48 from both sides
-48 -48
w^2 + 13w - 48 = 0 Now find two numbers that their product is -48 and their sum 13.
The numbers 16 and -3 works, because 16* -3 = -48 and 16 + (-3) = 13.
Rewrite the whole equation in this form.
w^2 + 16w -3w - 48 = 0 Now factor on the left side.
w(w + 16) -3(w+16) = 0 Factor out w+16
(w+16)( w-3) = 0 Now set each of the expressions to equal to 0 and solve for w.
w+ 16 = 0 or w-3 = 0
-16 -16 +3 +3
w = -16 or w = 3
-16 can't be use to represent distance so w has to equal 3 and this means the width is 3.
The length is 13 meters more than the width so 3 + 13 will be the width.
l = 3 + 13
l = 16
Can like terms have different exponets?
Answer: "Like terms" are terms whose variables (and their exponents such as the 2 in x^2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.

which parent functions do not have a domain of all real numbers?
Using domain concepts, it is found that the two most known functions that do not have a domain of all real numbers are fractions and even roots.
---------------------
The domain of a function is composed by all possible values that the input can assume.Functions such as linear functions and quadratic functions have no restrictions, thus, their domain is all real numbers.---------------------
In fractions, there are is a restriction, that the denominator cannot be zero, thus, values for the input which make the denominator zero are outside the domain, and the domain is not all real numbers.In even roots, there is a restriction, as the even roots of negative numbers do not exist in the real domain, and thus, values for the input which makes the number inside the root negative are outside the domain, and the domain is not all real numbers.Thus, the most known functions that do not have a domain of all real numbers are fractions and even roots.A similar problem is given at https://brainly.com/question/13136492

Step-by-step explanation:
Start by distributing:
y - 3 = 1/2(6-2x)
y - 3 = 3 -x
Add three to both sides:
y = 6 - x
Rearrange to make it look like an equation of a line:
y = -x + 6
Now all you have to do is plug in the points to see which point makes both side equal to one another. When you plug in (4,2), you get 2=2 which shows that that point is on the line.
