The speed of the wind is changing according to the function V(t)=−t2+30 , where t = time in minutes after 6:00 p. M. And V(t) = wind speed in miles per hour (mph). Which statement best describes the meaning of the equation V(20)−V(10)=−5 ? In a period of 5 minutes, the wind speed increased from 10 mph to 20 mph. The wind speed decreased by 5 mph between 6:10 p. M. And 6:20 p. M. The wind speed increased by 5 mph between 6:10 p. M. And 6:20 p. M. In a period of 5 minutes, the wind speed decreased from 20 mph to 10 mph.

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true
