We know that
in the right triangle ACD
Applying the Pythagoras theorem
AC²=AD²+CD²------> AD²=AC²-CD²-----> AD²=5²-4²---> AD²=9----> AD=3

let
∅=angle CAD
tan ∅=4/3 

in the right triangle CDB
the angle DCB is equal to ∅
tan ∅=DB/CD-------> DB=CD*tan ∅------> DB=4*(4/3)----> DB=16/3

AB=AD+DB-----> 3+16/3----> AB=25/3----> AB=8.33

the answer is

Answer:

Dominio de una Raíz cuadrada

Cuando tenemos una raíz, para estudiar su existencia debemos saber que una raíz existe si y solo sí el radicando (lo que está dentro de la raíz) sea mayor o igual a cero.

Por lo tanto deberemos estudiar el signo de lo que se encuentra dentro de la raíz; y determinar las zonas positivas y las raíces que son las zona de existencia de la función raíz o dominio de esta función.

In a restaurant 72 out of 108 tables are booths. What is the ratio of tables that are booths to the total number of tables.
denpristay [2]

Answer:

The ratio of tables that are booths to the total number of tables = \frac{72}{108}

Step-by-step explanation:

The number of tables in a restaurant, p = 108

The number of table that are booths, q = 72

Then, the ratio of tables that are booths to the total numbers of tables = \frac{q}{p}

                                                                 = \frac{72}{108}
