Ill give a ! the population of a local species of dragonfly can be found using an infinite geometric series where a1 = 30 and the common ratio is two fifths. write the sum in sigma notation and calculate the sum that will be the upper limit of this population.

Hello,

50.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically
