Answer:
Eduardo necesita 64 metros de malla para cercar el terreno completo.
Step-by-step explanation:
Por Geometría recordamos que un cuadrado es una figura geométrica con cuatro lados de igual longitud y cuatro ángulos internos rectos. Hallamos la longitud del lado frontal por la Ecuación General de la Longitud de un Segmento de Recta:
(Eq. 1)
Donde:
, - Componentes independientes inicial y final, medidos en metros.
, - Componentes dependientes inicial y final, medidos en metros.
- Longitud del segmento de recta, medidos en metros.
Si conocemos que y , entonces la longitud del segmento de recta es:
El metraje requerido para cercar el terreno es el perímetro de ese lugar, es decir, cuatro veces la longitud del lado frontal. Es decir:
(Eq. 2)
Donde es el perímetro del cuadrado, medido en metros.
Si , entonces el metraje requerdo para cercar el terreno es:
Eduardo necesita 64 metros de malla para cercar el terreno completo.

B.
(0, 1)
C.
(3, 4)
D.
(0, 7)
Answer:
D. (0,7)
Step-by-step explanation:
We are given that,
The point (-2,-3) is transformed by the composition .
That is, the point is first reflected across x-axis and then translated 2 units to the left and 4 units up.
Thus, the image of (-2,-3) is given by,
(-2,-3) → (-2,3) → (-2+2,3+4) = (0,7)
That is, the image of (-2,-3) after transformation is (0,7).
So, option D is correct.
Which of the following is a correct statement about this relation?
A. The slope of the line represented by this table is -2 and the y-intercept is -4.
B. The slope of the line represented by this table is 2 and the y-intercept is 7.
C. The slope of the line represented by this table is 2 and the y-intercept is -4.
D. The slope of the line represented by this table is -2 and the y-intercept is 7.
Answer:
Option B - The slope of the line represented by this table is 2 and the y-intercept is 7.
Step-by-step explanation:
Given : The ordered pair below represent a linear relation below x and y.
(-3,1), (-2,3), (-1,5), (0,7), (1,9), (2,11)
The slope form is
where m is the slope of line and c is the y-intercept.
or to find slope between two points are
Since they are ordered pairs so, there slopes were same
Let take points (-3,1), (-2,3)
Therefore, the slope of the given linear function is 2
Now, we have to find y intercept we put in slope form
Given pairs are ordered therefore, they satisfy the above equation so let point (-2,3)
So, slope of the line is 2 and y-intercept is 7.
Therefore, Option B is correct.
