Good luck!!!

 

Tues 1/17

Math 3- TEST THURS 1/19 Exponential Applications and Log and Exponential inequalities

Make sure you know how to do the problems from last week's Review Sheet # 9, 11, 15, 18, 20, 22.

Answers to today's review:

(Answers may be a little different due to rounding)

1. t = 835.9 yrs (may be up to 847.1 if rounding)

2. r= -.000121  t = 15,682.8 yrs

3. t = 3013.7 yrs

4. r= -.4581 t= 1.51

5. r= -.022

t=71.7 (exact) 73.2 if use r=-.022

6. r= -.0000286   t=80,390.66 (exaxt)  80,509.96 using rounded r

7. Use A = P ( 1-r)^t    $6495.39

8. Use A = P(1+r)^t  $4637.09

b) t=30.99 or 31 years

Thurs 1/12
