John and marsha are calculating the width of the lake shown in the figure. they are preparing a report for school and want to create a model of the lake in the report. if they make the length of the short leg of the triangle in the figure 3 inches long, how long will they make the long leg?

C. 5.2 inches.

Step-by-step explanation:

The length of the long leg is obtained from the following geometrical relation:

So, the right answer is C.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

c > -10.55

step-by-step explanation:
