Consider the function f given by f(x)=x*(e^(-x^2)) for all real numbers x.
Find the value of integral from 0 to infinity of [x*f(x)]dx given the fact that the integral from 0 to infinity of (e^(-x^2))dx = root pi / 2

total of apples - take away four

6-4 = 2

answer is 2 apples

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.

i believe a. 12x≥120 is the answer

dont't really have enough info here but its likely

sss for the three sides being congruent ( its stands for side side side)

or

sas   for side angle side.   so a side is congruent and and angle and a side
