The answer is: "72" .
______________________________________________
(input value, or "x") / 10 = y = f(x);

When y = 7.2, what is the value of "x" ?

x / 10 = 7.2 ;

x = (7.2) * 10 = 72 .

Find the height <br> 11in 14in<br> h=

jeka57 [31]

Answer:

$h = \sqrt{72}in$

Step-by-step explanation:

We have a right triangle with long side of 11in and smaller sides 14in/2=7in and h.

We know that

$h^2 + (7in)^2 = (11in)^2\\h^2 = 121in^2 - 49in^2 = 72in^2\\h = \sqrt{72}in$
