find the ratio of the lengths of a pair of corresponding sides
in two similar polygons if the ratio of their areas is 36: 121.

6 : 11

Step-by-step explanation:

Given 2 similar figures with ratio of sides = a : b, then

ratio of areas = a² : b²

Here ratio of areas = 36 : 121, thus

ratio of sides = : = 6 : 11

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
