3,6,12,24,48
write a recursive function rule for the sequence

Step-by-step explanation:

a1 = 3

a2 = 3 x 2 = 6                 [ a1 x 2 ]

a3 = 6 x 2 = 12                [ a2 x 2]

a4 = 12 x 2 = 24              [ a3 x 2 ]

a5 = 24 x 2 = 48             [ a4 x 2 ]

Therefore the recursive formula is :

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
