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

The area of Brians rectangular Garden in square feet can be found by using the expression 6(2 x + 5y) Use the distributive prope
algol [13]
Given the area, to rewrite the function using distributive property we get:
6(2x+5y)
using distributive property we open the parenthesis, this will give us:
6×2x+6×5y
simplifying the above we get
=12x+30y

Answer: 12x+30y

What is the least common multiple. Thanks.
o-na [289]

Before we start, find the LCM of 9, 5, and 5, which is 1. The least common multiple for the x is x^3, because it is the smallest exponent. The smallest multiple for y is 0, because the last factor doesn't even have y. For z, it is z^2. So your answer is 1x^3z^2, or just x^3,z^2.
