use the given transformation to evaluate the integral. 2y2 da, r where r is the region bounded by the curves xy = 2, xy = 4, xy2 = 2 and xy2 = 4; u = xy, v = xy2

sorry, i don't know i just need points, i'm new here. chao

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

dont know

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
