In the United States, which is rapidly swept by the "epidemic tsunami" triggered by Delta, the number of new crown inpatients has exceeded 100000 for the first time since January this year, and medical resources in many states have turned red: beds are exhausted, medical staff are in short supply, hospitals are overcrowded... More new crown patients have died because they can't wait for ICU beds.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
