-2 = KM, just simplify the equation.
F(x) = 4x - 9
let f(x) = y, this implies that x = f⁻¹(y)
y = 4x - 9 Let us solve for x.
4x - 9 = y
4x = y + 9
x = (y + 9)/4
Recall that x = f⁻¹(y),
x = (y + 9)/4
f⁻¹(y) = (y + 9)/4
That means that for f⁻¹(x)
f⁻¹(x) = (x + 9)/4
Hope this explains it.
The correct answer is the first option
Answer:
59.38 ft
Step-by-step explanation:
The person and his shadow form a triangle. The tree and its shadow also form a triangle. The triangles are similar triangles, so the lengths of corresponding sides are proportional.
Let the unknown tree height be h.
(person's height)/(person's shadow) = (tree height)/(tree's shadow)
(75 in.)/(48 in.) = h/(38 ft)
(25)/(16) = h/(38 ft)
16h = 25 * 38 ft
16h = 950 ft
h = 59.375 ft
h = 59.38 ft
