Acompany is looking to design a new cover for their smartphone. the scale drawing of the design is shown below. the coordinates of the actual cover are: h' (10,0); i' (0, 0); j' (0, 16); k' (10,16). is the design of the cover similar to the actual cover?

The coordinates of the corners in the scale drawing of the desing are:

H = (2,0)
I = (0,0)
J = (0,4)
K = (2,4)

That makes the lengths of the segments be:

HI = 2 - 0 = 2
JK = 2 - 0 =2
JI = 4 - 0 = 4
KH = 4 - 0 = 4

Now check the segments of the actual cover:

H'I' = 10 - 0 = 10
K'J' = 10 - 0 = 10
J'I' = 16 - 0 = 16
K'H' = 16 - 0 = 16

Now check corresponding segments meet proportionality criterium, which is needed for similarity:

H'I' / HI = 10 /2 = 5

K'J' / KJ = 10 / 2 = 5.

So far we this is fine.

JI / J'I' = 16 / 4 = 4 then not, the ratio is not the same ratio of the other two segments, which implies that the scale used for the vertical segments is different to the scale used for the horizontal segments, driving to a non similar figure.

no, because the corresponding sides are not proportional

Answer from: Quest

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
