Answer:
1 f(n) = 3(5)^x-1
2 f(n) = 40(3/2)^x-1
Step-by-step explanation:
The first number in the sequence, times the (multiplicative factor)^ x-1 is the rule for geometric sequences.
To solve this, you must find the initial weight of the cucumber. To do this, you must divide the weight by the percentage of water and multiply it by 100.
(21/92)×100=22.83lbs.
Then, you multiply it by 85% and divide it by 100. Or simply multiply it by 0.85.
22.83×0.85=19.41lbs.
Question 1:
For this case we have an equation of the form:

Where,
- <em>k: inverse variation constant.
</em>
Then, substituting values we have:

From here, we clear the value of k.
We have then:

Answer:
the constant of inverse variation is:

Question 2:
For this case we have:

Where,
- <em>k: constant of variation.
</em>
Then, substituting the value of the constant we have:

We now substitute the value of x:

Answer:
the value of y when x = 4 is:

60 children tickets and 190 adult tickets were sold.
<u>Step-by-step explanation:</u>
Let the no. of adult tickets sold be 'a'
Let the no. of children tickets sold be 'c'
Total tickets sold = 250
Cost of 1 children ticket = $2.5
Cost of 1 adult ticket = $4
Total money collected= $910
Given that,
a + c = 250
a = 250 - c
4a + 2.5c = 910
Substitute a value
4(250 - c) + 2.5c = 910
1000 - 4c + 2.5c = 910
1000 - 1.5c = 910
-1. 5c = -90
1.5c = 90
c = 90/1.5
c = 60
a + c = 250
a + 60 = 250
a = 190
60 children tickets and 190 adult tickets were sold.
