una compañia de relojes desea promocionar un cierto modelo de reloj de pared con motivo de su proximo aniversario. Ellos te soli

Annette [7]

Queremos encontrar las ecuciones de las circunferencias que definen el reloj dado.

Las ecuaciones son:

x^2 + y^2 = 16cm^2

x^2 + y^2 = 196cm^2

Lo primero que debemos hacer para escribir una ecuacion, es definir nuestro eje de coordenadas.

Pondremos el punto (0, 0) en el centro de la cartulina.

Debemos recordar que la ecuación de un circulo de radio R centrado en el punto (a, b) se escribe como:

(x - a)^2 + (y - b)^2 = R^2

En este caso tendremos dos ecuaciones de circulos, ambas centradas en el centro de la cartulina, que es el punto (0, 0).

Para el primer caso tendremos un radio R = 4cm, que es el circulo interno que contiene las horas 12, 3, 6, y 9.

Otro de radio R' = 14cm, que contiene el resto de horas.

Entonces las dos ecuaciones de los circulos seran:

x^2 + y^2 = (4cm)^2 = 16cm^2

x^2 + y^2 = (14cm)^2 = 196cm^2

In△XYZ , XY¯¯¯¯¯¯=7in , YZ¯¯¯¯¯=5in , and XZ¯¯¯¯¯=4in . This triangle is reflected across the x-axis to result in △X'Y'Z' . Whic

ki77a [65]

Answer:

B

Step-by-step explanation:

Reflection is a transformation that preserves lengths.

Triangle XYZ, with side lengths XY = 7 in, YZ = 5 in, XZ = 4 in, is reflected across the x-axis to result in △X'Y'Z'.

This means that corresponding sides have the same lengths:

XY = X'Y' = 7 in;
XZ = X'Z' = 4 in;
YZ = Y'Z' = 5 in.

Find the perimeters of both triangles:

$P_{XYZ}=XY+XZ+YZ=7+4+5=16\ in\\ \\P_{X'Y'Z'}=X'Y'+X'Z'+Y'Z'=7+4+5=16\ in$

Hence, only option B is true.

22. The mean of 15 observations is 32. Find the resulting mean, if each observation is: (i) increased by 3 (ii) decreased by(v)

Lubov Fominskaja [6]

Answer:

35 ;

32 + v

51.2

Step-by-step explanation:

If each observations in a particular set is increased or decreased by a uniform or fixed number, the mean of the resulting output will also increase by the same amount

Hence,

For 15 observations whose mean is 32

If each observation is increased by 3, then the resulting mean will also increase by 3 ; hence, new mean = 32 + 3 = 35

If each observation is decreased by v ; the resulting mean would also decrease by v ;

32 - v

If each observation is increased by 60% ; the resulting mean will be ;

(1 + 60%) * initial mean

(1 + 0.6) * 32

1.6 * 32 = 51.2
