Question

Four students provide the following approximations for StartRoot 0.89 EndRoot. Anyah states that StartRoot 0.89 EndRoot is between 0.44 and 0.45 because 0.44 less-than StartFraction 0.89 Over 2 EndFraction less-than 0.45. Matthew states that StartRoot 0.89 EndRoot is between 0 and 1 because 0 less-than 0.89 less-than 1. Rhoda states that StartRoot 0.89 EndRoot is between 0.9 and 1.0 because 0.9 squared less-than 0.89 less-than 1.0 squared. Ming states that StartRoot 0.89 EndRoot is between 0.93 and 0.95 because (0.93) squared less-than 0.89 less-than (0.95) squared.

Answer 1

Answer:

Rhoda states that StartRoot 0.89 EndRoot is between 0.9 and 1.0 because 0.9 squared less-than 0.89 less-than 1.0 squared. Ming states that StartRoot 0.89 EndRoot is between 0.93 and 0.95 because (0.93) squared less-than 0.89 less-than (0.95) squared.
