Algebra  2  Unit  10  Study  Guide  Conics  

 Simplify.  

1. -­‐24  +  -­‐33     2.  27  –  -­‐16     3. (31)(7)   4. 48  ÷  -­‐12    Evaluate.  

5. Solve  the  system  of  equations.    7𝑥 + 3𝑦 = 245𝑥 + 𝑦 = 16  

 6. Factor.    2𝑥! + 4𝑥 − 16    

 7. Determine  the  zeros.    𝑓 𝑥 = −𝑥! − 6𝑥 + 16  

 8. Find  the  x-­‐intercepts  of  the  function.    

𝑓 𝑥 = 𝑥! − 3𝑥 + 7    

9. Simplify.    𝑖!!"  

10.    Simplify.    𝑥! + 5𝑥 + 4𝑥! − 7𝑥 − 44

   

11. Simplify.    32!!  

 12. The  number  of  hats  and  headbands  varies  

inversely.    If  there  can  be  4  hats  and  6  headbands,  how  many  hats  would  there  need  to  be  to  have  1  headband?  

 

13.    Divide.    𝑥! + 2𝑥 + 1𝑥! − 9

÷𝑥 + 1𝑥 − 3

       14. Determine  the  equation  of  the  parabola  with  its  focus  at  (3,  -­‐3)  and  its  directrix  at  y  =  1.  

   

15. Write  the  equation  of  the  conic  in  standard  form.    4(𝑥 + 3)! − 3𝑦! = 36    

16. Identify  the  type  of  conic  section.    −7𝑥! − 2𝑦! − 9𝑥 + 𝑦 − 16 = 0    

17. Write  the  equation  in  standard  form  for  an  ellipse  with  center  (5,  4),  vertex  (8,  4)  and  focus  (6,  4).    

18. Write  the  equation  of  the  circle  with  a  radius  of  6  and  a  center  at  (-­‐1,  0).    For  problems  19-­‐21,  use  the  conic  given  below.    

𝑦 + 4 =72𝑥 − 8 !  

19. Identify  the  type  of  conic  section.  20. Identify  (ℎ, 𝑘).  21. Identify  p.  

 For  problems  22-­‐25,  use  the  conic  given  below.  

𝑦 + 2 !

25−𝑥!

100= 1  

22. Identify  the  type  of  conic  section.  23. Identify  a.  24. Identify  b.  25. Identify  c.
