The discriminant is the number under the square root of the quadratic formula

The discriminant formula is 
If D = 0, then the whole square root portion is 0 meaning we end up with the solution

Step-by-step explanation:
The sun subtends an angle  rad
 rad
Angular velocity equation is 
where  is angular velocity and t is time.
 is angular velocity and t is time.
Earth spins at a rate of : 
 rad/s
  rad/s
Isolating time (t) from angular velocity equation gives:




 
        
             
        
        
        
Answer:
The percent error based on the average measurements is 0.8%.
Step-by-step explanation:
The standard equation for percent error is [(original - actual)/original} x 100.  The original amount is 100 degrees celcius.  Your average measurement can be found by adding the three temperatures together and dividing by the number of temperatures collected:  98.5 + 99.3 + 99.8 = 297.63/3 = 99.2.  When we place our numbers into the equation and solve, we get:  (100 - 99.2)/100 = 0.008 x 100 (to get our percentage) = 0.8%.
