In math class, 4 students complete individual surveys to determine the percentage of high school teachers that have a second job. which two surveys show proportional results? a) a and b b) b and d c) a and d d) b and c

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

i took the test: )

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

answer: 7. if the functions had a negative leading coefficient and is of even degree, which statement about the graph is true?
