if a flagpole casts a shadow 18 feet long and at the same time a nearby mailbox casts a shadow 3 feet long, how tall is flagpole if the mailbox is 4 feet tall?

345

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.
