Answer:
translates up 8 and 5 left
Step-by-step explanation:
To find the distance (x) it translate up, -3 + x = 5 where x = 8
To find the distance (x) it translate left, 2 + x = 7 where x = 5
Answer:
(x, y) → (x-5, y+8)
Step-by-step explanation:
A translation is a type of transformation that moves a figure up, down, left or right.
Calculate the change in the coordinates by subtracting the coordinates of point D from the coordinates of point D':
[tex]\implies (x_{D'}-x_D, y_{D'}-y_D)[/tex]
[tex]\implies (2-7, 5-(-3))[/tex]
[tex]\implies (-5, 8)[/tex]
Therefore, to map point D onto point D', move 5 units left and 8 units up.
Therefore, the translation rule that maps point D(7, -3) onto point D'(2, 5) is:
(x, y) → (x-5, y+8)which is closest to 8? 7.5 , 7 6/10 , 7 2/5 , 7.02?

HELP PLS! How does the graph of g(x) = (x + 2)3 − 6 compare to the parent function of f(x) = x3?
It is to be noted that the graph of g(x) = (x+2)³ -6 compares to the parent function f(x) = x³ in that g(x) is shifted 2 units to the left and 6 units down. See the explanation below.
What is a parent function?A parent function in mathematics is the simplest function in a family of functions that retains the concept of the whole family.
Here is how the transformation of a function can occur
Any change can occur during the transformation of a function.
Typically, they can be moved horizontally or vertically (by changing inputs or outputs), stretched (by multiplying outputs or inputs), and so on.
If the initial function is y = f(x), and the horizontal axis represents inputs and the vertical axis represents outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units, y=f(x+c) (same output, but c units earlier)Right shift by c units, y=f(x-c)(same output, but c units late)Vertical shift
Up by d units: y = f(x) + dDown by d units: y = f(x) - dStretching:
Vertical stretch by a factor k: y = k × f(x)Horizontal stretch by a factor k: y = f(x/k)A function sets the value of one set's elements to the value of another set's specified element.
Given that the parent function is f(x)=x³, while the transformed function is g(x)=(x+2)³ - 6. Therefore, the transformation of the parent function that results in the transformed function is that g(x) is shifted 2 units to the left and 6 units down.

What is a function?The function is a type of relation, or rule, that maps one input to a specific single output.
A change can be moved horizontally or vertically (by changing inputs or outputs), stretched (by multiplying outputs or inputs), and so on.
If the initial function is y = f(x), and the horizontal axis shows the inputs and the vertical axis shows outputs, then:
Horizontal shift would be Left shift by c units; y=f(x+c) and Right shift by c units; y=f(x-c)
Vertical shift would be Up by d units; y = f(x) + d and Down by d units; y = f(x) - d
Stretching would be as Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given that the parent function is; f(x)=x³,
And the transformed function is; g(x)=(x+2)³ - 6.

How many seconds does it take for lighting to strike 7250
Answer:
Pues hablemos primero de lo que sucede antes de apagar la luz y usemos como ejemplo el viaje de un solo fotón.
Un fotón proveniente de un bombillo de luz blanca se dispara en línea recta hacia la pared. El material que cubre la pared, en este caso la pintura, tiene ciertas propiedades físicas y la energía del fotón es absorbida por un electrón de algún átomo de esa superficie. Ocurre una excitación del electrón, el cual ahora tiene más energía de la que normalmente tiene en su estado fundamental, y para regresar a su estado fundamental emite parte de esa energía como un nuevo fotón, este último de menor energía (frecuencia) que el anterior. La frecuencia dependerá del material y esa nueva frecuencia es la que da color a la pared. La luz blanca está compuesta por fotones de distintas frecuencias. Los de baja frecuencia son absorbidos y lo que se emite es en forma de calor, lo cual no puedes ver con tus ojos. Los de alta frecuencia tienen suficiente energía para que la energía que se re-emite sea visible y posiblemente sea re-emitida, cada vez con menos energía. Uno habla de que la luz “rebota” en el objeto. (Aunque “rebotar” no es necesariamente la acción correcta, voy a usar el término para simplificar).
Ahora digamos que ese fotón que “rebotó” en la pared rebota en otra pared y otra pared. Ese fotón es solo visible si en ese rebotar llega a tu ojo antes de que su energía sea demasiado baja. No podemos ver el calor ni las microondas que son fotones de baja energía. Al final la energía se va a convertir en calor, el cual es invisible al ojo humano.
Ese es el trayecto de un solo fotón. El bombillo produce un flujo de fotones en todas direcciones. Hay que recordar que esos fotones viajan a la velocidad de la luz. Cuando el bombillo se apaga, se interrumpe el flujo de fotones. Si se movieran a la velocidad del agua en una manguera, verías el flujo rebotando por varios segundos hasta que los fotones que más han rebotado desaparecen de tu vista por aquello de la baja frecuencia energética. Pero al viajar a la velocidad de la luz, el tamaño de la habitación se hace irrelevante y nuestra experiencia es prácticamente instantánea.
¿A donde va la luz? La luz no sale de la habitación sino que la calienta.

What is a number?
A number is a quantitative entity that may be used to tally, measure, and name things. The natural numbers 1, 2, 3, 4, and so on are the original instances. Number words can be used to represent numbers in language. Individual numbers can be represented more generically by symbols known as numerals; for example, "5" is a numeral that represents the number five. Because only a small number of symbols can be memorized, fundamental numerals are often structured in a numeral system, which is a systematic method of representing any number. The most prevalent numeral system is the Hindu-Arabic numeral system, which allows any number to be represented using a combination of 10 fundamental numeric symbols known as digits.

c) Suppose that you take a random sample of 5,000 people from the U.S. population.Make a table that shows the expected number of people in your sample who come fromeach of the four age groups
In order to determine the number of people in the sample for each age group, here are the steps:
1. Determine what proportion in the entire population the population of each group. To get the proportion, simply divide the population of each respective group by the entire population.
2. To get the number of samples for each group, multiply the proportion by 5,000 and round the answer to the nearest whole number.
Now, let's apply the steps above in each group.

For those aged 45 - 64,
[tex]\begin{gathered} Proportion:81,489,445\div308,745,538=0.2639372395 \\ Number\text{ }of\text{ }Samples:0.2639372395\times5,000=1,319.68\approx1,320 \end{gathered}[/tex]The expected number of samples for people aged 45-64 is 1,320.

And it is divisible by (x+2),(x-1),and (x-3) the remainders are respectively -48,0 and 2.
Here we need to find the value of p, q and r.
Let us consider that the equations,
x + 2 = 0 then x = -2
x - 1 = 0 then x = 1
x - 3 = 0 then x = 3.
Now, apply these values on the polynomial expression then we get,
f(-2) = (-2)³ + p(-2)² + q(-2) +r = -48
f(-2) = -8 + 4p - 2q +r = -48
f(-2) = 4p - 2q +r = -48 + 8
f(-2) = 4p - 2q + r = -40 ----------------------(1)
Apply the value of x as 1, then we get
f(1) = (1)³ + p(1)² + q(1) +r = 0
f(1) = 1 + p + q + r = 0
f(1) = p + q + r = -1 ----------------------(2)
Apply the value of x as 3, then we get
f(3) = (3)³ + p(3)² + q(3) + r = 2
f(3) = 27 + 9p + 3q + r = 2
f(3) = 9p + 3q + r = -25 ----------------------(3)
Now we have to solve the equation (2) and (1), then we get,
=> (4p -p) + (-2q - q) + (r - r) = -40 - (-1)
=> 3p -3p = -39
Divide it by 3, then we get
=> p - q = -13 ----------------------(4)
Similarly, solve equations (2) and (3), then we get,
=> (9p - p) + (3q - q) + (r - r) = -25 - (-1)
=> 8p + 2q = -24
Divide it by 2, then we get,
=> 4p + q = -12 ---------------------------(5)
Solve the equations (4) and (5), then we get,
=> (4p + p) + (q - q) = -12 - (-13)
=> 5p = 1
=> p = 1/5
Apply the value of p on equation (4), then we get the value of q as,
=> (1/5) - q = -13
=> -q = -13 -1/5
=> -q = -66/5
Apply the value of p and q on equation (2), then we get,
=> 1/5 + (-66/5) + r = -1
=> -65/5 + r = -1
=> -13 + r = -1
=> r = 12
Therefore, the value of p is 1/5, q is -66/5 and r is 12.

The front suspension system of a passenger car typically has coiled springs attached to the front wheels. a typical spring has a spring constant k of about 82,000 k/m
If the front suspension system of a car has coiled springs of spring constant(k) of about 82,000N/m attached to the front wheels, then the force required to compress this spring by 1.2 cms will be 984N.
As per the question statement, the front suspension system of a passenger car has coiled springs attached to the front wheels and a typical spring has a spring constant "k" of about 82,000 k/m.
We are required to calculate the force required to compress this spring by 1.2 cms
To solve this question, we will need to apply the formula to calculate the force to compress a spring, which is known as the Hooke's Law. So, as per the Hooke's Law, the force (F) required to compress a spring of spring constant (k) by "x" units, can be represented as
[F = (k * x)]
Now comparing the RHS of the Hooke's Law equation with the data provided in the question statement, we get, (k = 82000 N/m) and
(x = 0.012 m), and using these values in the Hooke's law equation, we get, the force required to compress a spring of spring constant(k) of about 82,000N/m by 1.2 cms will be (82000 * 0.012)N = 984 N.
Spring Constant: The magnitude of force required to compress or stretch a spring by unit distance, is known as it's spring constant, and it varies from spring to spring, typically being based on the constituent elements of the spring.To learn more about Spring Constants, click on the link below.

The 14.2 cm correct 1 decimal place is 14.2 after rounding to the nearest 0.1 or the tenth place.
What is rounding off the number?Rounding is a technique to reduce a large number to a smaller, more approachable figure which is very similar to the actual. Rounding numbers can be achieved in a variety of ways.
It is given that:
14.2 cm correct 1 decimal place
14.2
Rounded to the nearest 0.1 or
the Tenths Place.
Rounded to the nearest tenth place. The 2 in the tenth place rounds down to 2 or stays the same because the digit to the right in the hundredth place is 14.2
Thus, the 14.2 cm correct 1 decimal place is 14.2 after rounding to the nearest 0.1 or the tenth place.

The suitable expression will be (0.65x = 7) and the cost of traveling 15 miles would be $9.75.
What are expressions?A number, a variable, or a combination of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation. Word illustration: The product of 8 and 3. Word illustration: The product of 8 and 3 is 11 written as 8 + 3.So, the flat rate is $7 and we're charged $0.65 per mile:
Let, 'x' be the number of miles traveled.Then the suitable expression will be:
0.65x = 7Cost if we traveled 15 miles:
So, 0.65x = y where x = 15.
0.65x = y0.65(15) = y9.75 = yIt would cost $9.75 for 15 miles.
Therefore, the suitable expression will be (0.65x = 7) and the cost of traveling 15 miles would be $9.75.

the weight of items produced by a machine is normally distributed with a mean of 7 ounces and a standard deviation of 3 ounces. what percentage of items will weigh between 4.3 and 8.65 ounces? a. 47.52%
27.80% is percentage of items .
What percentage means?
Percentage ,a comparative figure denoting one hundredth of any quantity. One percent (symbolized as 1%), being the hundredth component, is represented as 100 percent, while 200 percent signifies twice the amount specified.Mean = 7
standard deviation = 3 ounces
Required % = p (5.6<x < 7.1 ) × 100 = ?
z = x - μ/σ = 5.6 - 7/2
z = 7.1 - 7/2 = 0.05
∴ P(5.6 < x < 7.1 ) = p ( - 0.7 < z < 0.05 )
p( z < 0.05 ) - p ( z < - 0.7)
= 0.51994 - 0.24196 ≅ 0.2780
So, required % = 0.2780 × 100
