It takes the planet about 1500 Earth days to complete a full orbit.
What is the planet's average speed in kmh-1 to 3sf?
Answer:
change days to hours so 1500×24=36000

The expression (x² + 3) / (x-3)(x-1) is the simplified form of the given expression. which is the correct answer would be an option (B).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given below as:
(x-3)/(x-1) + 6/(x-3)
To simplify the expression, we can first combine the terms that have a common denominator:
(x-3)²+ 6(x-1) / (x-3)(x-1)
We can simplify the expression further by using the fact that
(x² + 9 - 6x + 6x - 6) / (x-3)(x-1)
Combine the likewise terms and apply the arithmetic operation,
(x² + 3) / (x-3)(x-1)
Thus, the simplified expression is:
(x² + 3) / (x-3)(x-1)

simplify (3s^8)^-5 write your answer using only positive exponents. help please!!
Answer:
1 / ( 243s^40 )
Step-by-step explanation:
For this problem, we need to know that a negative exponent simply can be rewritten in the opposing part of the fraction, for this case, the denominator. So we can simplify as shown:
(3s^8)^-5
= 1 / (3s^8)^5
= 1 / 3^5 * s^8^5
= 1 / 243 * s^40
= 1 / ( 243s^40 )
Cheers.
The expression [tex]\left (3s^8 \right )^{-5}[/tex] is simplified as equal to [tex]\boldsymbol{3s^{-40}}[/tex]
Define exponent.The amount of times an integer is multiplied on its own is referred to as an exponent.
Given expression is [tex]\boldsymbol{\left (3s^8 \right )^{-5}}[/tex]
Use the formula: [tex]\boldsymbol{\left ( a^m \right )^n=a^{mn}}[/tex] to simplify the expression.
[tex]\left (3s^8 \right )^{-5}=3s^{8\times (-5)}[/tex]
[tex]=\boldsymbol{3s^{-40}}[/tex]
So, the expression is simplified as equal to [tex]\boldsymbol{3s^{-40}}[/tex]

Answer:
40) 105 miles (mi)
42) 3.2 centimeters (cm)
Step-by-step explanation:
First determine which part of the ratio corresponds to what. Once you have figured that out, divide by the part of the ratio that corresponds to your given part and then multiply that by the other part of the ratio to derive the quantity.
If a:b
Then a × a/b = b, and b × a/b = a.
You can think of : as "to".
For example, you are given a map with a scale ratio of 1 in : 20 mi, this means that for every inch of the map, there is an actual distance of 20 miles.
So in this situation, the left part of the ratio is the length of the map in inches, and the right part of the ratio is the real distance in miles. For x inches of the map, there is 20 x miles of actual distance. Therefore 3.5 inches has an actual distance of 3.5 × 20 miles or 105 miles of actual distance.
For problem 2, you are given a ratio of 1 m : 2 cm, this means that for every 1 meter of the drawing, there is 2 cm of the plant. Therefore if you have 1.6 meter of the map, then you have 1.6 × 2 cm of the plant or 3.2 cm. For both situations the left part of the ratio is 1 which means that you just multiply by the right part of the ratio by which you are given.
The graph of g is the graph of translated horizontally 5 units to the right. If f(x) = 3x + 2 , what is the equation of the function g?
Answer:
f(x) = 3(x-5) + 2
Step-by-step explanation:
The x coordinates are all shifted to the right, which is the positive direction. Subtracting 5 from the x coordinate is a horizontal right shift.

Un taxista compra un coche el 1 de enero de 2013 por 30.000 € . El coche tiene una vida útil de 10 años y un valor residual de 3000 €. El 30 de junio de 2015 vende el coche por 25.000 € . ¿ Qué beneficio ha obtenido?
Answer:
El taxista obtiene un beneficio de 1.750 € por la venta del taxi el 30 de junio de 2.015.
Step-by-step explanation:
El coche experimenta depreciación a medida que cubre su vida útil hasta caer a su valor residual, es decir, el valor del bien al término de su vida útil. En primer lugar, derivamos una ecuación del precio actual del coche en función del tiempo transcurrido bajo el supuesto de que existe una relación lineal:
[tex]C(t) = C_{o} + \frac{C_{f}-C_{o}}{\Delta t} \cdot t[/tex], para [tex]0\leq t\leq \Delta t[/tex] (1)
Donde:
[tex]C(t)[/tex] - Precio actual del coche, medido en euros.
[tex]C_{o}[/tex] - Precio inicial del coche, medido en euros.
[tex]C_{f}[/tex] - Precio residual del coche, medido en euros.
[tex]\Delta t[/tex] - Vida útil del coche, medida en años.
[tex]t[/tex] - Tiempo actual del coche, medida en años.
El precio actual del coche se obtiene a partir de los siguientes parámetros:
([tex]C_{o} = 30.000\,EUR[/tex], [tex]C_{f} = 3.000\,EUR[/tex], [tex]\Delta t = 10\,yr[/tex], [tex]t = 2.5\,yr[/tex])
[tex]C(t) = 30.000\,EUR +\left(\frac{3.000\,EUR-30.000\,EUR}{10\,yr} \right)\cdot (2.5\,yr)[/tex]
[tex]C(t) = 23.250\,EUR[/tex]
El beneficio derivado por la venta del coche ([tex]\Delta C[/tex]), medido en euros, se obtiene mediante la siguiente sustracción:
[tex]\Delta C = V-C[/tex] (2)
Donde:
[tex]V[/tex] - Precio de venta del coche, medido en euros.
[tex]C[/tex] - Precio actual del coche, medido en euros.
Si tenemos que [tex]V = 25.000\,EUR[/tex] y [tex]C = 23.250\,EUR[/tex], el beneficio obtenido por la venta es:
[tex]\Delta C = 25.000\,EUR-23.250\,EUR[/tex]
[tex]\Delta C = 1.750\,EUR[/tex]
El taxista obtiene un beneficio de 1.750 € por la venta del taxi el 30 de junio de 2.015.
