The population of a local species of dragonfly can be found using an infinite geometric series where a1 = 48 and the common ratio is one fourth. write the sum in sigma notation and calculate the sum that will be the upper limit of this population.

The sum of the given geometric series and its sigma notation is given below :

Step-by-step explanation:

First term, a = 48

The series is given to be geometric series and the sum of geometric series is given by :

And for sigma notation,

the answer to this question is in the pic

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
