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 right triangle ABC, angle C is a right angle, AB is 25 units long, and BC is 24 units long. What is the lenght of AC?
ycow [4]

Answer:

7 units long

Step-by-step explanation:

We are given a right triangle ABC

  • AB = 25 units
  • BC = 24 units

We are required to determine the length of AC

  • We are going to use the Pythagoras theorem;
  • According to the theorem, if a and b are the legs of a right triangle and c is the hypotenuse, then;

a² + b² = c²

In this case;

AB is the hypotenuse and BC is one of the legs of the triangle;

Therefore;

AB² = BC²+AC²

Rearranging the formula;

AC² = AB² - BC²

       = 25² - 24²

       = 625 - 576

       = 49

AC = √49

     = 7

Thus, AC is 7 units long

pav-90 [236]

Answer:

1, 5, 17, 53, 161

Step-by-step explanation:

Given:

  • a_1=1
  • a_n=3a_{n-1}+2

First five terms of the sequence:

a_1=1

a_2=3a_1+2=3(1)+2=5

a_3=3a_2+2=3(5)+2=17

a_4=3a_3+2=3(17)+2=53

a_5=3a_4+2=3(53)+2=161
