Which relation is not a function? a) input: name of student; output: gpa b) input: price of an item; output: upc code eliminate c) input: name of student; output: birth month d) input: next door neighbors; output: zip code e) input: name of high school; output: total number of scholarships awarded

(B)

Steps:

(A) valid function because a student can only be associated with one GPA

(B) not a function: given a price there may be multiple products and therefore multiple UPC codes

(C) valid function: given a student there is only one possible month value

(D) valid function: if the neighbors are identified uniquely, and live only in one residence, then there is only one zip code for them

(E) valid function: number of scholarships awarded by a given high school is a single value for that entity.

hope this !

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
