The population of a local species of dragonfly can be found using an infinite geometric series where a1 = 42 and the common ratio is 3/4. write the sum in sigma notation and calculate the sum that will be the upper limit of this population.

we are given

first term is

common ratio is

now, we can find nth term

now, we can plug values

now, we can write in sigma form

now, we can find sum

we can use formula

now, we can plug values

we get

so, option-D.................Answer

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
