Given the f (x) vs x curve, and the magnitude of the areas as shown, the value of y x a 5 7 2 b c -2 2 12 Cannot be determined http://nm.mathforcollege.com

A steel cylindrical shaft initially at room temperature is immersed in a dry-ice/alcohol bath. A layman estimates the reduction in diameter by using The layman uses value of the thermal expansion coefficient at -108oF in the above formula. Seeing the graph on your right, the magnitude of contraction you would calculate instead will be ______________than the layman’s estimate. Less More Same 30 http://nm.mathforcollege.com

The number of significant digits in 2.30500 is 4 5 6 7 http://nm.mathforcollege.com

The absolute relative approximate error in an iterative process at the end of the tenth iteration is 0.007%. The least number of significant digits correct in the answer is 2 3 4 5 7 http://nm.mathforcollege.com

The number 6.749832 with 3 significant digits with chopping is 6.75 6.749 6.750 http://nm.mathforcollege.com

The binary representation of (0.3)10 is (0.01001……...)2 (0.10100……...)2 (0.01010……...)2 (0.01100……...)2 http://nm.mathforcollege.com

In a five bit fixed representation, (0. 1)10 is represented as (0 In a five bit fixed representation, (0.1)10 is represented as (0.00011)2. The true error in this representation most nearly is 0.00625 0.053125 0.09375 9.5×10-8 http://nm.mathforcollege.com
