Answer:
Step-by-step explanation:
We need at least two points to write the equation of a straight line.
The recursive formula that Elijah wrote is:
When we substitute n=0, we get:
The points (0,30) and (1,37) lies on this line.
The equation of this line is of the form:
where b =30 is the y-intercept and m=7 is the slope.
We plug in these values to get:
Note that the slope of the line is equal to the common difference of the Arithmetic Sequence.
You could also use the two points to find the slope:
Answer:
The vector that describes their hike from their starting position to their final destination is .
Step-by-step explanation:
In this problem we assume that orthogonal axes coincide with the north and east. We proceed to translate each sentence from statement into vectorial equations:
(i) <em>A group of hikers walks 3 miles east and then 1 mile north:</em>
(ii) <em>After taking a break, they then hike 4 miles east to their final destination:</em>
The vector that describes their hike from their starting position to their final destination is the sum of the vectors deducted above. That is:
(1)
The vector that describes their hike from their starting position to their final destination is .
