Una compañía de transporte público cobra " "x" " por transportar cierta mercancía 20 kilómetros y " "z" " por transportar la misma mercancía 25 kilómetros. A) Determine la relación entre la tarifa total y la distancia recorrida, suponiendo que es lineal. B) ¿Cuál es la tarifa mínima por transportar esta mercancía? C) ¿Cuál es la cuota por cada kilómetro que la mercancía es transportada?" x = $190. 00 z = $242. 0. Prueba con las sugerencias que aparecen más abajo o introduce una consulta nueva
Utilizando los dos puntos dados, veremos que la relacion lineal es:
A) y = ($10.4 /km)*x -$18A) y = ($10.4 /km)*x -$18B) -$7.6C) $10.4 /km¿Como encontrar la relacion lineal?Una ecuación lineal se escribe como:
y = a*x + b
donde a es la pendiente y b es la ordenada al origen.
Sí sabemos que una linea pasa por los puntos (x₁, y₁) y (x₂, y₂), entonces la pendiente va a ser:
a = (y₂ - y₁)/(x₂ - x₁).
Aca tenemos los dos puntos:
(20km, $190)
(25 km, $242)
Entonces la pendiente será:
a = ($242 - $190)/(25km - 20km) = $10.4 /km
y = ($10.4 /km)*x + b
Para obtener el valor de b, usamos uno de los puntos. Evaluando en x = 20km deberiamos obtener y = $190, entonces:
$190 = ($10.4 /km)*20km + b
$190 = $208 + b
$190 - $208 = b = -$18
Entonces la ecuación es:
y = ($10.4 /km)*x -$18
B) La tarifa minima es lo que obtenemos con x = 1 km, entonces es:
y = ($10.4 /km)*1 km - $18 = -$7.6
Notar que da un valor negativo, lo que indica que la relación quizas no es lineal.
C) La cuota por kilometro es la pendiente de la relación lineal, en este caso será: $10.4 /km.

prove that if∠ 1 ≅ ∠2, then ∠2 ≅ ∠3. what is m∠1?
We see that angle 1 and angle 2 are equal.
By the vertical angle theorem, the opposite (vertical) angles of two intersecting lines are congruent, we see that angle 1 and angle 3 must be equal. Since angle 1 and angle 2 are equal, then angle 2 and angle 3 are equal.
And for angle 1, it must be 90 degrees, because if it was any other angle measure, angle 1 and angle 2 could never be equal
If you are given the graph of g (x) = log Subscript 2 Baseline x, how could you graph f (x) = log Subscript 2 Baseline x 5? Translate each point of the graph of g(x) 5 units up. Translate each point of the graph of g(x) 5 units down. Translate each point of the graph of g(x) 5 units left. Translate each point of the graph of g(x) 5 units right.
The function that translates every point of the function f(x) 5 units above can be represented by g(x)=log₂x + 5.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
As the function that is given to us is f(x)=log₂x, therefore, the function can be written as,
[tex]y=f(x)=\rm log_2x[/tex]
Now, since we need every point to be up by 5 units, therefore, every value of x should be +5 on the y axis, therefore, the function that will represent that every point up by 5 units of the function f(x) can be written as,
[tex]g(x) = y+ 5\\\\g(x) = f(x) + 5\\\\g(x) = {\rm log}_2x + 5[/tex]
Hence, the function that translates every point of the function f(x) 5 units above can be represented by g(x)=log₂x + 5.

Answer:
2.5
Step-by-step explanation:
Add up the 5s of the left side first and you will get 25. Then you add up the 5s on the otherside and you will get 10. Subtract the 10 from the 25 to get 15. Finally, divide 15 by 6 to get the weight of each triangle, 2.5
1: 5 x 5 = 25
2: 5 x 2 = 10
3: 25 - 10 = 15
4: 15/6 = 2.5
The weight of each triangle is 2.5
Have an amazing day!
PLEASE RATE!!
Answer: 2.5
Step-by-step explanation:
What we know:
Both sides need to be equal, and one side already has a constant defined value.
That value is 25 (units)
How to solve:
By using a simple algebraic equation, we can find the value of a triangle's weight. X will represent a square's weight, and y will represent a triangle's weight.
Process:
Set up equation 5x = 2x + 6y
Substitute 5(5) = 2(5) + 6y
Simplify 25 = 10 + 6y
Cancel out -10 -10
15 = 6y
Separate variable /6 /6
Solve 2.5 = y
Solution: y (triangle weight) = 2.5
You can check this by adding 2.5 6 times (15) to 5 2 times (10). This will equal 25, which would balance out the other side
Terry has an investment account which compounds interest continuously at an annual interest rate of 1. 4%. After 3 years, he has $1700 in the account. How much money did he initially place in the account? Round your answer to the nearest dollar. Do NOT round until you've calculated the final answer
Answer:
$1,630.08
Step-by-step explanation:
The value of an amount earning interest continuously compounded is given by the formula ...
A = Pe^(rt)
The value of P can be found by dividing by its coefficient:
P = A/(e^(rt)) = Ae^(-rt)
P = $1700·e^(-0.014·3) ≈ 1630.0786

each side. Tell whether the triangles are similar or not similar and explain why.
Triangle 1: 18, 24, 36
Triangle 2: 16, 18, 24
Answer:
Step-by-step explanation:
Given "Two triangles that have three pairs of proportional sides are always similar."
Triangle 1: 18, 24, 36
Triangle 2: 16, 18, 24
16/18 = 8/9
18/24 = 3/4
24/36 = 2/3
So the three pairs of sides are not proportional and the triangles are not similar.
No as
One ratio is unsimilar so triangles are not similar
