Answer:
a.) 4 : 9
b.) 16 : 81
Explanation:
a.) Ratio of perimeter will still be
4 : 9
b.) The two similar triangles ΔABC and ΔDEF as shown from the attached figures. That is
AB/DE = AC/DF = BC/EF
It is apparent that ΔAPB and ΔDEQ are also similar as all respective angles are equal. Hence,
AB/DE = AP/DQ = BP/EQ
Moreso ΔABC = 1/2 × BC × AP and ΔDEF = 1/2 × EF × DQ and
ΔAPB/ΔDEQ = BC/EF × AP/DQ
But
AP/DQ = AB/DE = BC/EF
and hence
ΔAPB/ΔDEQ = BC/EF × BC/EF
= BC^2/EF^2 and as
BC/EF = AC/DF = AB/DE
ΔAPB/ΔDEQ = AC^2/DF^2 = BC^2/EF^2
= AB^2/DE^2
Hence if sides of two similar triangles are in the ratio a:b, their areas are in the proportion a^2:b^2
As in given case sides are in the ratio of 4:9.
ratio of their areas is 4^2:9^2 or 16:81.
If I were a forensic scientist and asked to identify drugs at a crime scene, you would take samples where residue is likely to be present.
<h3>What is a crime scene?</h3>
A crime scene is a term used to refer to the location where a crime occurs and the arrangement of evidence to determine how events related to the crime occurred at that location.
<h3>What is a sample?</h3>
A sample is a tool used in forensic investigation to determine the existence of an element or substance at a crime scene.
For example, in this case we can take samples from the corpse's hands, nose and mouth to determine if he used drugs prior to his death.
