Find the inverse function. f (x)=1/2x+6

Lana71 [14]

The inverse of this function is f(x) = 2x - 12.

You can find the inverse of any function by switching the f(x) and x values in the equation. Then you can solve for the new f(x) value. The result is your inverse function. The work for this one is below.

f(x) = 1/2x + 6 ----> switch f(x) and x

x = 1/2f(x) + 6 ----> subtract 6

x - 6 = 1/2f(x) ----> multiply by 2

2x - 12 = f(x) ----> change the order for consistency.

f(x) = 2x - 12

Part A )a painter leans a ladder up against a building. The base of the ladder is placed 7 feet from the building to reach a hei

Lana71 [14]

Answer:

Part A). 25 feet

Part B). 16.25 feet

Step-by-step explanation:

Part A). By applying Pythagoras theorem in ΔABC,

AC² = AB² + BC²

AC² = (24)² + 7²

AC² = 576 + 49

AC = √625

= 25 feet

Part B). By applying Pythagoras theorem in ΔABC,

AC² = AB² + BC²

(25)² = (19)² + x²

625 = 361 + x²

x² = 625 - 361

x = √264

x = 16.25 feet
