Answer: The function that models the distance they drive is
f(x) = 50x + 20 where x is the time in hours
reasonable domain: 0 ≤ x ≤ 3
Step-by-step explanation:
examples:
95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.
120 = 50(2) + 20 This means that after 2 more hours they will reach their destination.
There is a little ambiguity in the question. The function could be written as if they are starting out. f(x) = 50t
20 = 50(.4) At 50 mph it took .4 hours to go 20 miles.
120 = 5(2.4) The whole trip took 2.4 hours.
Given:
The sequence is:
To find:
The 6th term of the given sequence.
Solution:
We have,
Here, the first term is:
The ratio between consecutive terms are:
The given sequence has a common ratio 5. So, the given sequence is a geometric sequence.
The nth term of a geometric sequence is:
Where, a is the first term and r is the common ratio.
Substitute 
to get the 6th term.
Therefore, the 6th term of the given sequence is 50000.
Since there are 2 rows with 8 in each row the answer is 16 chairs
Answer:
Melissa has a student dictionary on her desk. Her dictionary contains 99 pages. In this dictionary, more words start with the letter "S" than any other letter, occupying 11 full pages.
If she opens up the dictionary at random, what is the probability that the page contains words starting with "S"?
