<h2><u>El conjunto de parejas ordenadas que no es una función es: </u></h2><h2> </h2><h2><u>Alternativa C: {(-2,1),(-1,0),(0,1),(-1,2),(2,2)} </u></h2>

<h3>Una función se define como un conjunto de parejas ordenadas (x, y) donde no se repite el valor de "x" (corresponde al dominio de la función) </h3><h3> </h3><h3>En el caso específico del ejercicio, la alternativa C no corresponde con una función ya que tienen dos parejas con el mismo valor de "x":  {(-2,1), (-1,0), (0,1), (-1,2), (2,2)} </h3><h3> </h3><h3>Estos pares están en negrita, y el valor repetido subrayado. </h3>

Marat540 [252]
This is a 30-60-90 triangle, in which the side opposite of the 90 degrees is the longest side (2), the side opposite of the 60 degrees is the √3 (2√3 in this case), and the last side (opposite of the 30 degrees) is the (1)

2√3/√3 = 2

So the side opposite  of the 30° = 2

a) the width is 2 miles

The length of the side walk is 2(a)
a = 2

2(2) = 4

b) The length of the sidewalk is 4 miles

hope this helps

How would I do this problem?
kenny6666 [7]

If it's a geometric sequence then:

a_1=27;\ a_2=27\\\\r=\dfrac{a_2}{a_1}\to r=\dfrac{27}{36}=\dfrac{3}{4}=0.75\\\\a_{n+1}=a_nr\\\\a_3=27\cdot0.75=20.25\ CORRECT

We calculate the fourth and fifth term of the sequence:

a_4=a_3r\to a_4=20.25\cdot0.75=15.1875\\\\a_5=a_4r\to a_5=15.1875\cdot0.75=11.390625

Answer:

In year 4 15.1875 animals.

In year 5 11.390625 animals.
