Answer:

1, 2, 8, 128, 32768

Step-by-step explanation:

$recursive \: formula: \\ a _{n} = 2. {( a_{n - 1} )}^{2} \\ \\ a _{1} = 1...(given) \\ \\ a _{2} = 2. {( a_{2 - 1} )}^{2} = 2 {(a _{1} )}^{2} = 2 {(1)}^{2} \\ \\ a _{2} = 2\\ \\a _{3} = 2. {( a_{3 - 1} )}^{2} = 2 {(a _{2} )}^{2} = 2 {(2)}^{2} \\ \\ a _{3} = 8\\ \\a _{4} = 2. {( a_{4 - 1} )}^{2} = 2 {(a _{3} )}^{2} = 2 {(8)}^{2} \\ \\ a _{4} = 128\\ \\a _{5} = 2. {( a_{5 - 1} )}^{2} = 2 {(a _{4} )}^{2} = 2 {(128)}^{2} \\ \\ a _{5} = 32,768\\ \\$

Thus the first five terms are: 1, 2, 8, 128, 32768.

Why are there two solutions for the equation |6 + y| = 2? Explain.

Luba_88 [7]

Since it is in absolute value it switches the negative to a positive so here let me show you

|6+y| = 2

If you try -4 you get 2 in a positive form so -4 is one correct.

The second correct one is -8 because 6-8 is -2 but as I was saying before how the absolute value changes it into positive, that means -2 would be switched to 2 meaning that -8 is also a correct answer.

If you need more help just search up what absolute value is.

Y=9x+3>> is this true, false, or open??

AfilCa [17]

First you have to know the value of either x or y. If x is 2, and y is 20, it would be false.

But if x is 2 and y is 21, it would be true.

So, the equation is open!
