Given the explicit rule f(n)=31+8n find the recursive rule

• f(1)= 39 f(n)=f(n-1)+8

• f(1)= 39 f(n)=f(n-1)+10

• f(1)= 47 f(n)=f(n-1)+8

• f(1)= 47 f(n)=f(n-1)-8

Write a recursive formula for the following sequence: 16,8, 4, 2,...

• f(1)=16

  f(n)=2f(n-1)

• f(1)=16

  f(n)=0.5f(n-1)

• f(1)=16

  f(n)=f(n-1) + 0.5

• f(1)=16

  f(n)=f(n-1) - 8

Janice is looking into joining a gym for one year. Best Gym costs $30 a month and has a one time membership fee of $100. Get In Shape charges $50 a month. The graph shows the equations for both lines. What is true about the graph? Choose all that apply.

• At 5 months, both gyms have cost $250

• Get In Shape is the better buy if she stays for the whole year.

• Best Gym is the better buy if she stays for the whole year.

• If she decides to leave the gym at 3 months, Best Gym is the better buy.

A man is climbing down from 100 feet high descending 30 feet per minute. Write an equation in slope-intercept form that models this situation.

• y = 100 - 30x

• y = 100 + 30x

• y = 100x + 30

• y = 100x - 30
