If triangle MNO is similar to triangle PQR, which statement is true about the two triangles?
Neko [114]
The first one. Segment NO is proportional to segment QR, and angles M and P are congruent.

In similar triangles, their angles are congruent but their sides are only proportional. That is why the last three are not true.

Lindsay is creating a bridge out of dried pasta and glue. In her plans, she sketches the graph to determine the lengths of the n
alexgriva [62]
From the graph shown it can be seen that the bridge is represented by a parabola with vertex of (5, 8) and roots of 1 and 9.

Recall that the vertex form of the equation of a parabola with vertex (h, k) is given by
y=a(x-h)^2+k

Thus, the equation of the given graph in vertex form is given by
y=a(x-5)^2+8

Also, recall that the equation of a parabola with roots, p and q, is given by
y=a(x-p)(x-q)

Thus the equation of the given graph can be given by
y=a(x-1)(x-9)

To get the value of a, we equate both equations and solve as follows:
a(x-5)^2+8=a(x-1)(x-9) \\  \\ a(x^2-10x+25)+8=a(x^2-10x+9) \\  \\ ax^2-10ax+25a+8=ax^2-10ax+9a \\  \\ 25a-9a=-8 \\  \\ 16a=-8 \\  \\ a=- \frac{8}{16} =- \frac{1}{2}

Therefore, the <span>function that Lindsay used to create her design is
f(x)=-0.5(x-5)^2+8

a_sh-v [17]

Answer:

a. A Estela le entregaron (100 + 30 + 3) tejuelones = 133 tejuelones y aún necesita (138 - 133) tejuelones = 5 tejuelones para que reciba todo el pedido. b.  Don Antonio llevó (150 + 60 + 7) tejuelones = 217 tejuelones.

Step-by-step explanation:

<h3>Parte a </h3>

¿Cuántos tejuelones le entregaron a Estela? ¿Cuántos tejuelones es la diferencia para que Estela reciba todo el pedido realizado?

Datos

<u>Pedido de Estela</u>:

138 tejuelones.

<u>Le entregaron</u>:

Dos (2) Paquetes de 50 tejuelones.

Dos (2) Paquetes de 15 tejuelones.

Tres (3) Sueltos.

Operación

Para determinar cuántos tejuelones le entregaron a Estela, efectuamos las siguientes operaciones para determinar el número de tejuelones que le entregaron:

<u>Dos (2) Paquetes de 50 tejuelones</u>

2 * 50 tejuelones = 100 tejuelones

<u>Dos (2) Paquetes de 15 tejuelones</u>

2 * 15 tejuelones = 30 tejuelones

Es decir, <em>multiplicamos el número de paquetes por la cantidad de tejuelones que trae cada uno</em>.

Ahora sumamos el total de ambas cantidades y le adicionamos los <em>tres (3) tejuelones sueltos</em>:

(100 + 30 + 3) tejuelones = 133 tejuelones.

Pero Estela pidió 138 tejuelones, así que aún necesita:

(138 - 133) tejuelones = 5 tejuelones para que reciba todo el pedido realizado.

Respuestas

<em>¿Cuántos tejuelones le entregaron a Estela?</em>

A Estela le entregaron (100 + 30 + 3) tejuelones = 133 tejuelones.

<em>¿Cuántos tejuelones es la diferencia para que Estela reciba todo el pedido realizado?</em><em> </em>

Estela aún necesita (138 - 133) tejuelones = 5 tejuelones para que reciba todo el pedido.

<h3>Parte b</h3>

¿Cuántos tejuelones llevó Don Antonio?

Datos

<u>Pedido de Don Antonio</u>

Tres (3) paquetes de 50 tejuelones.

Cuatro (4) paquetes de 15 tejuelones.

Siete (7) tejuelones sueltos.

Operaciones

Para determinar cuántos tejuelones le entregaron a Don Antonio, debemos multiplicar el número de paquetes por la cantidad de cada uno y sumar los siete (7) tejuelones sueltos, es decir, seguimos el mismo procedimiento de la pregunta anterior.

<u>Tres (3) paquetes de 50 tejuelones</u>

3 * 50 tejuelones = 150 tejuelones.

<u>Cuatro (4) paquetes de 15 tejuelones</u>

4 * 15 tejuelones = 60 tejuelones.

Ahora sumamos estas cantidades y le adicionamos <em>los siete (7) tejuelones sueltos</em>:

(150 + 60 + 7) tejuelones = 217 tejuelones.

Respuesta

<em>¿Cuántos tejuelones llevó Don Antonio?</em>

Entonces, considerando los resultados anteriores, tenemos que Don Antonio llevó (150 + 60 + 7) tejuelones = 217 tejuelones.
