4. true or false. for all subquestions below assume that a is an m × n real matrix and s is an n × n symmetric matrix (a) t f all eigenvalues of at a are non-negative. (b) t f at a and aat have same set of eigenvalues if not counting the repeated zeros. (c) t f: if a has only positive singular values then the nullspace of a is an empty set. (d) t f let rx) -, x r", then for any real mumber k; r(kx) > r(x). (e) t f: let d be an n × n real diagonal matrix, then the maximum and minimum values of r(x) ? , x e r", are the largest and smallest diagonal entries of d.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

i think it might be a but you might want a second opinion

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
