Two sailboats are traveling along the same path away from a dock, beginning from different locations at the
same time. John's boat begins 30 miles from the dock and
is 50 miles from the dock after 5 hours. The distance of
Roberta's boat from the dock is represented by the
function y = 5x + 25, where x represents time and y
represents the distance from the dock.
Which boat was farther from the dock at the beginning, and which traveled
more quickly?

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
