the number 1 is written on a piece of paper and then passed around the room to each of the 50 students in turn. each of the stud

Gnom [1K]

Answer:

The last term on the paper after 50 students = $2^{(50)} -1$

Step-by-step explanation:

The general term of the equation:

Here, the first term = 1

Second term = 2(1) + 1 = 3 = 4 - 1 = $2^{2} - 1$

Third Term = 2(a2) + 1 = 2(3) + 1 = 7 = 8 -1 = $2^{3} - 1$

Fourth term = 2( a3) + 1 = 2(7) + 1 = 15 = 16 - 1 = $2^{3} - 1$

Continuing this way, we get

Last term : $a_n = 2^n -1$

So, the 50th term of this sequence is

$a_{(50)} = 2^{(50)} -1$

Hence, the last term on the paper after 50th student changes it = $2^{(50)} -1$

Find the value of X A: 2 B: 4 C: 6 D: 8

11111nata11111 [884]

Using the Pythagorean theorem:

x^2 + (x-2)^2 = (√20)^2

Simplify the right side:

x^2 + (x-2)^2 = 20

Subtract 20 from both sides:

x^2 + (x-2)^2 - 20 = 0

Factor:

(x-4)(x+2) = 0

Solve for each x:

x = 4 and x = -2

The side cant be a negative value, so the answer would be x = 4

The answer is B.
