Interesting question. Thanks for posting.
The small triangle has the height as the missing side.
Part One: Givens
a = 144
b = height = ?
c = 240
a^2 + b^2 = c^2
144^2 + b^2 = 240^2
20736 + b^2 = 57600 Subtract 20736 from both sides
b^2 = 57600 - 20736
b^2 = 36864
√b^2 = √36864
b = 192
Solve for x
The relationship between the height (b) and 144 and x is
b^2 = 144 * x
36864 = 144x Divide by 144
x = 256
A:b = 8:5 b:c = 3:4
since both sides have b. make b the same. multiply the left by the right side b value of 3 and multiply the right by the left side b value of 5.
3(a:b) and 5(b:c)
3 (8:5) and 5(3:4)
24:15 15:20
now that both sides have the same b value
a:b:c = 24:15:20
Answer:
Suppose f and g are two functions such that
1. (g ◦ f)(x) = x for all x in the domain of f and
2. (f ◦ g)(x) = x for all x in the domain of g
then f and g are said to be inverses of each other. The functions f and g are said to be
invertible.
. Properties of Inverse Functions: Suppose f and g are inverse functions.
• The rangea of f is the domain of g and the domain of f is the range of g
• f(a) = b if and only if g(b) = a
• (a, b) is on the graph of f if and only if (b, a) is on the graph of g

Answer: D
Step-by-step explanation:
If f(x) = 4x - 2 and g(x) = 2x + 7 then which of the following gives f(g(3))?
g(3) = 2*3+7 = 6+7 = 13
f(g(3))=f(13) = 4* 13 -2= 52 -2 = 50
