A kite flying in the air has a 10ft line attached to it. Its line is pulled taut and casts a 9ft shadow. Find the height of the kite. If necessary, round your answer to the nearest tenth.

20ft

Step-by-step explanation:

9+10=19, round that to the nearest tenth and you get 20. Make me brainleist if you want (Ik i spelled brainleist wrong...) Thx

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
