For a certain decision, the time it takes to respond is a logarithmic function of the number of the choices faced. One model is R=.17+.44log(N) where R is the reaction time in seconds and N is the number of choices. Required:
a. Find the average rate of change of the reaction time when the number of choices goes from 10 to 100.
b. Find the rate of change of the reaction time with respect to the number of choices.

Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10

Which expression is equivalent to -5(3x - 6/7)

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
