The sum of the second and third terms of geometric sequence is 280,and the sum of the fifth and the sixth terms is 4375. Determine the common ratio and the first 10 terms.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.

step-by-step explanation:

the value of x is 28.2

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
