The two discs in the figure rotate at different speeds. The smaller disc rotates once every 6 minutes. The larger disc takes 21 minutes to rotate. If they both start rotating at the same time, how long until the two arrows align again?

x=30

step-by-step explanation:

quit

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
