Tommy is looking at a tall building. The building is casting a shadow 48
feet long. Tommy is 6 feet tall and
his shadow is 4 feet. How tall is the
building?

tommy is 6ft and makes a 4ft tall shadow

which means that the building would make a shorter shadow then its height.

48/4=12

12*6=72

72ft

(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.
