Recall the double angle identity:
With 
measuring between 0º and 90º, we know 
. So from the Pythagorean identity, we get
Then
Answer:
A = ...-5π ,-4π ,-3π, -2π, -π, 0, π, 2π, 3π, 4π, 5π....
A = {x ∈ N, πx}
To find the median, find the middle number. Since there are 10 numbers, find the 5th one and the 6th one and find their average.
The two numbers are both 9, so its safe to say that the median is 9.
to find the median of the first and quartile, you have to place a line where the median should be and find the median of that. Q1 and Q2 will be 5 and 11 (respectively).
Its easy to see that all the lines start at the lowest point given and end at the largest point given, so match Q1, the median, and Q3
The only line that has lines at the Q1, median, and Q3 we figured out is answer C, so therefore it is the answer.
Answer:
-6
Step-by-step explanation:
La diferencia entre el denominador y el númerador de la fracción es:
64 - 8 = 56.
<h3>
¿Como encontrar la fracción?</h3>
Tendremos una fracción de la forma:
Tal que:
Eso es un sistema de ecuaciones
Primero, podemos reescribir la primer ecuación como:
Ahora podemos reemplazar "b" en la segunda ecuación por "8a", así obtenemos:
Ahora podemos obtener el valor de b:
La diferencia entre a y b es:
