Select the equation that is a rational function
A. y=x
B. y=x/(x+3)
C. y=x^3
D. y=2^x
Answers
Answer:
y = x/x+3 is a rational function
Step-by-step explanation:
Here, we want to select the equation that is a rational function
rational functions are such that could be expressed as the division of one function by another
For example;
f(x) = g(x)/h(x)
is a rational function
so, if we applied this here,
we have it that;
y = x/x+ 3 is a rational function

Answer:
Step-by-step explanation:
To solve this equation, group like terms together: 'w' terms on the right and constants on the left:
-10 = 7w. Then:
w = -10/7 (exact) or w ≈ 1.43

if you use the 10 feet ladder base is 6 feet
if you use 12 feet ladder base is 8.94 feet
if you use 15 feet ladder base is 12.69 feet
Step-by-step explanation:
you know the ladder length so you know the hypotenuse
you can use a^2 + b^2= c^2
for example you use the 10 feet ladder
8^2+b^2 = 10^2
64 + b^2 = 100
subtract 64 from both sides
b^2=36
to get rid of the exponent find square root
b= 6
you can plug in the different values like 15 or 12

Step-by-step explanation:
Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal
thus, we have it that;

16 * x = 11 * 28.8
x = (11 * 28.8)/16
x = 19.8

If we multiply a number by 5, then we add it by 3.5, and we divide the result by 2, and from the new result we subtract 7.6 we obtain 6.65. Find out the number.
Answers
Answer:
the number is 5
Step-by-step explanation:
((n x 5 + 3.5) ÷ 2) -7.6 = 6.65
( 5n + 3.5) ÷ 2 = 14.25
5n + 3.5 = 28.5
5n = 25
n = 5

Observa las siguientes imágenes formadas por círculos:
Figura 1 (un circulo) Figura 2 (5 círculos)
-¿Cuántos círculos tendrá la Imagen 10?
-¿Cuántos círculos más tendrá la imagen 12 respecto de la imagen 7? ¿Puedes saberlo sin necesidad de encontrar la cantidad de círculos de cada imagen? ¿Cómo?
Answers
2.la imagen 12 tendrá 45 puntos y la 7 tendrá 25 puntos
La diferencia de puntos entre la figura 7 y 12 serán seran 20 puntos
-si lo pude saber sin la necesidad de encontrar la cantidad de los círculos de las imágenes porque cada ves vamos agregando 4 puntos
Veremos que en la imagen 10 hay 37 circulos, y la diferencia entre las imagenes 12 y 7 es de 20 circulos.
¿Como encontrar el patrón?
Primero, debemos contar la cantidad de circulos que tenemos en las imagenes mostradas.
En la primera, tenemos 1 circulo.En la segunda, hay 5 circulos.En la tercera, hay 9 circulos.En la cuarta, hay 13 circulos.Entonces podemos ver que en cada imagen se agregan 4 circulos, es decir tenemos una secuencia aritmetica, de tal forma que la imagen número N tendremos:
[tex]C_N = 1 + (N - 1)*4[/tex]
Entonces, cuantos circulos hay en la imagen 10? para ver eso reemplazamos N por 10.
[tex]C_{10} = 1 + (10 - 1)*4 = 37[/tex]
¿Cuántos círculos más tendrá la imagen 12 respecto de la imagen 7?
Para ver esto calculamos:
[tex]C_12 - C_7 = (1 + (12 - 1)*4) - (1 + (7 - 1)*4) = 11*4 - 6*4 = 20[/tex]
Es decir, la image 12 tiene 20 circulos más que la imagen 7.

You start out with a penny that will double every day for 30 days. Find the average rate of change from day 7 to day 14. Remember that this function has already been shown to be f(x)=0.01(2)^x.
Answers
Answer:
$23.22 per day.
Step-by-step explanation:
For a general function f(x), the average rate of change between A and B (when B > A) is:
[tex]r = \frac{f(B) - f(A)}{B - A}[/tex]
In this case we know that the function is:
f(x) = 0.01*(2)^x
And we want to find the average rate of change from day 7 to day 14
Then if we use the above equation we get that the rate of change from day 7 to day 14 is:
[tex]r = \frac{0.01*(2)^{14} - 0.01*(2)^7}{14 - 7} = 23.22[/tex]
Because this equation is in dollars, we can conclude that the average rate of change between day 7 and day 14 is $23.22 per day.
An average rate of change between A and B (where B>A) for a generic function [tex]f(x)[/tex] is:
[tex]\to r=\frac{f(B)-f(A)}{B-A}\\\\[/tex]
In this situation, the function is:[tex]\to f(x) = 0.01\times (2)^x[/tex]
And we'd like to calculate the average rate of change from day 7 to day 14.Using the aforementioned equation, we can calculate the rate of change from day 7 to day 14 as follows:[tex]\to r=\frac{0.01\times 2^{14} -0.01 \times 2^7}{14-7}=23.22[/tex]
Since this equation is stated in dollars, we can calculate that the average rate of change between days 7 and 14 is [tex]\$23.22[/tex] each day.

Angle of a triangle measures 115° the other two angles are in the ratio of 4:9 what are the measures of those two angles
Answers
Answer:
20, 45
Step-by-step explanation:
A triangle has 180 degrees interior angle measure. One angle measure 115 so that means the other two angles must add up to 65.
The remaning angles form a ratio of 4:9. This means we must split 65 into a ratio of. 4:9
A ratio partition parts of something. We can add the ratio intergers to find it full length.
4+9=13.
Divide 65/13=5.
Multiply 5x4 and 5x9 serpately.

What is the remainder in the synthetic division problem below?
1|4 6 -3
A. 3
B. 7
C. 5
D. 9
Answers
The correct option is (b) i.e. In the given synthetic division, the remainder will be 7.
What is Remainder ?
The remainder is what "remains" after an activity is finished, as its name implies. In mathematics, it is impossible to divide 17 by 3 precisely. The leftover after division is the number 2, which is set aside.
Given : 1 | 4 6 -3
If we solve it further, we get
1 | 4 6 -3
| 4 10
| 4 10 7
Steps :
firstly we will write 4 as it is .
we will multiply 1 by 4 and write it in the second place, then we will add 6 and 4.
Similarly, we will multiply 1 by 10 and write it in the third place, then we will add -3 and 10 and finally get 7 as residual.
here, after solving, we get 7 in the end which is set aside.
So, the remainder will be 7.
Hence, the correct option is (b).
