1. Warm Up A long-distance telephone carrier charges $1.38 for international calls of 1 minute or less and $.36 for each additional minute. A. write a recursive formula for the situation B. Find the cost of a 7 minute phone call

2. List the terms of each number sequence of y-coordinates for the points shown on each graph. Then write a recursive routine to generate each sequence. U 0 =.5 U n =U n-1 +.5

3. List the terms of each number sequence of y-coordinates for the points shown on each graph. Then write a recursive routine to generate each sequence. U 0 =4 U n =U n-1 -1

4. List the terms of each number sequence of y-coordinates for the points shown on each graph. Then write a recursive routine to generate each sequence. U 0 = -1 U n =U n-1 +.25 U 0 = -.5 U n =U n-1 +1.5

5. A car is moving at a speed of 68 mi/hr from Dallas towards San Antonio. Dallas is about 272 mi from San Antonio. A) write a recursive routine to create a table of values relating time to distance from San Antonio for 0 to 5 hrs.
