One of your classmates argues in his persuasive speech, "what starving people need first is food and clean water--not counseling about the sad state of their governments, not advice about ways to attract new industry, and not pity over the loss of their self-esteem." what principle of persuasive speaking is this class member effectively using?

The principle of persuasive speaking that the class member is effectively using is the basic needs by which it needs to be satisfied before even considering the ones that are in higher level by which this will make the audience to be more attentive to the speech that one is sharing.

the answer is risk management planning

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
