Answer:
La regla del coseno establece que el cuadrado de la longitud de cualquier lado de un triángulo es igual a la suma de los cuadrados de la longitud de los otros lados menos el doble de su producto multiplicado por el coseno de su ángulo incluido.
Step-by-step explanation:
<em><u>GIVEN</u></em><em><u> </u></em><em><u>EQUATION</u></em><em><u> </u></em><em>:</em><em>-</em>
<em>x</em><em> </em><em>+</em><em> </em><em>6</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>9</em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em><u> </u></em><em><u> </u></em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>•</em><em>•</em><em>•</em><em> </em><em>(</em><em>i</em><em>)</em>
We have to find missing coordinate in ordered pair (2,?).
From ordered pair , we can observe that value of x is 2.
Putting value of x in equation (i).
2 + 6 y = 9
=> 6y = 9 -2
=> 6y = 7
=> y = 6/7
=> y = 0.8571428571
=> y = 0.86 (approx )
Now , ordered pair is ( 2, 0.86)

Answer:
Step-by-step explanation:
Factoring x2-6x-30
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -30
Step-1 : Multiply the coefficient of the first term by the constant 1 • -30 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is -6 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7
-2 + 15 = 13
-1 + 30 = 29
Answer:
0.4375
Step-by-step explanation:
