Researchers identified college students who generally were procrastinators or non-procrastinators. in a study, the students were asked to report throughout the semester how many symptoms of physical illness they had experienced. the study shows that late in the semester, procrastinating students reported more symptoms of physical illness than their non-procrastinating peers. complete parts (a) through (c) below. a. at the beginning of thesemester, procrastinators reported an average of 1.25 symptoms, increasing at a rate of 0.55 symptoms per week. write a function that models the average number of symptoms, y, after x weeks.? (use integers or decimals for any numbers in theequation.)

Given: ad¯¯¯¯¯ is an altitude. prove: ab2+ac2=cb2 right triangle a b c with right angle a. point d lies on side b c and segment a d is drawn. angle a d c is a right angle. drag and drop a reason into each box to correctly complete the two-column proof. statement reason ad¯¯¯¯¯ is an altitude, and ∠bac is a right angle. given ∠adb and ∠adc are right angles. definition of altitude ∠bac≅∠bda ? ∠bac≅∠adc ? ∠b≅∠b ? ∠c≅∠c reflexive property of congruence △abc∼△dba ? △abc∼△dac aa similarity postulate abbd=cbab ? ab2=(cb)(bd) cross multiply and simplify. acdc=cbac polygon similarity postulate ac2=(cb)(dc) cross multiply and simplify. ab2+ac2=ab2+(cb)(dc) addition property of equality ab2+ac2=(cb)(bd)+(cb)(dc) substitution property of equality ab2+ac2=(cb)(bd+dc) ? bd+dc=cb segment addition postulate ab2+ac2=cb2 substitution property of equality
