A factory purchased a machine for $35,000. the value of the machine depreciates at a rate of 10% each year.
Dafna1 [17]
If you're finding the future value: P=35,000(1-.1/1)^1. this is assuming you want to know the value of it after one year. if you want it to be more years, like two : P=35,000(1-.1/2)^2. When entered into the calculator enter it like so : 35,000(1-(.1/1))^1. when that's done you end up with $31,500. that's the machine's worth. it lost 3,500. 35,000-31500.

7. The new York Volleyball Association
Yuri [45]

Using a geometric sequence, it is found that after 3 rounds, 8 teams are left.

In a geometric series, the quotient between consecutive terms is always the same, and it is called common ratio q.

The general equation of a geometric series is given by:

a_n = a_1q^{n-1}

In which a_1 is the first term.

In this problem:

  • 64 teams were invited, thus a_1 = 64.
  • After each round, half the teams are eliminated, thus q = \frac{1}{2}.

The <u>number of teams after 3 rounds</u> is the 4th term of sequence, as the first is the initial number(0 rounds), thus:

a_n = a_1q^{n-1}

a_4 = 64\left(\frac{1}{2}\right)^{4-1}

a_4 = 8

After 3 rounds, 8 teams are left.
