Answer:

D Antenna #4

Step-by-step explanation:

As per given graph we can write the function

the intercept is zero, as x=0, y=0

at x=2, y=30 ⇒ 30= 2*15
at x=4, y=60 ⇒ 60= 4*15

The slope is 15, so the function is

y=15x

And the function for the antenna revolving at twice the rate would be

y=30x

Comparing data in given tables we can see it is D Antenna #4

x= 22 ⇒ y= 22*30= 660
x=24 ⇒ y= 24*30= 720

In the transformation ABC A'B'C', the preimage of B' is ____. . a0

Misha Larkins [42]

Answer:

Pre image of B' is B

Step-by-step explanation:

Given:

ABC is a triangle

A transformation is done on ABC so that the image is A'B'C'.

Note that transformations are of various types such as dilation, vertical shift, horizontal shift, rotation about a point, reflection on a line, etc.

In any type of transformation, corresponding vertices will be matched. In other words, A will become A', B will become B' and C will become C'.

Because of the property of the transformation to keep images similar and also transforming correspondingly the vertices we get preimage of B' would be nothing but B itself.

Write a linear function f with f(−10)=4 and f(−2)=4.

Orlov [11]

f(-10) = 4

f(-2) = 4

Since y is constant while x isnt we just dont need to put x

f(x) = 4

Los dueños de un restaurante cultivan sus propios

hammer [34]

Answer:

Quedan 2.083 m^3 de agua en el reservorio.

Equivalen a 2083 litros.

Step-by-step explanation:

Los dueños del restaurante tienen un reservorio de agua cuyo volumen es de 6.25 m^3.

Si han utilizado 2/3 del reservorio, esto implica que aún quedan en el reservorio una tercera parte del volumen original (1/3).

Entonces, la cantidad de metros cúbicos (m^3) de agua que quedan en el reservorio se puede calcular como:

$V=(1/3)\cdot V_0=(1/3)\cdot6.25\,m^3=2.083\,m^3$

Este valor equivale a un volumen en litros de:

$V=2.083\,m^3\cdot \dfrac{1,000\,l}{1m^3}=2,083\,l$
