Which relations are functions?
guapka [62]

Answer:

The 1st and 2nd graph are functions while the 3rd and 4th aren't.

Step-by-step explanation:

The first and second graph doesn't have more than one output for each input. The third and fourth graph isn't a function since there's more than one output for the same input given. If you do the vertical line test, then you'll know which one is a function and which one is not a function. Hope this helps :)

Find the missing number:
nirvana33 [79]

Answer:

20%

Step-by-step explanation:

Not sure if this is exactly correct, but let's say we start with 1 unit. If it increased by 25%, we get:

1 × 1.25 = 1.25 units.

Now, to get back to 1 unit, we need to find:

1.25 × ?  = 1

? = \frac{1}{1.25} = 0.80

So, 100% - 80 % = 20%

A 20% decrease.

Not completely sure though.

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.
