Mathematics and Scientific Calculator Review

Read the manual you got with your calculator and use this knowledge to answer the following questions. If you don't have a manual, it's your responsibility to somehow find out how to use your scientific calculator. This assignment may be collected and counted as homework. A quiz similar to this worksheet will be given shortly.
 
1.     100. = (50.0 + v)/2 (Tip: Cross Multiply and solve)     v = ______

 
2.     19.0 = (100. - 2.00)/ t                      t = ______

3.     v²  = 8.00²  + 2.00(9.80)3.20          v = ______

 (Tip: Don't forget to take the square root at the end)

4.      F = (6.70 X 10^-11) (6.00) (1.00 X 10³ )/(.70²)

       F = __________________ (Answer only in scientific notation) 

5.     v = 8.0 sin52.°                          v = ______

6.     F = (12.0 - 8.00² )/3.00              F = ______

7.   10.0 = V²/ 7.00     (Hint: Cross Multiply)  v = ______

 
8.   8.0t = 10.(5.0 - 3.0)                     t = ______

 
9.   100. = 1/2 (12.)x²                        x = ______

 
10.   1/5 + 1/3 = 1/R (Hint: Common Denominator, Reciprocate)  R = ___

 
11.   12. = 1/f   (Hint: Reciprocate both sides)      f = _______    (scientific notation)

 
12.  Solve this equation: sin x = .76  (hint: inverse sine) x =___
