Answer:

{f}^{ - 1} (x) = 9x + 18

Step-by-step explanation:

f(x) =  \frac{1}{9}x - 2

y = \frac{1}{9} x - 2

x =  \frac{1}{9}y - 2

x + 2 =  \frac{1}{9}y

9x + 18 = y

{f}^{ - 1} (x) = 9x + 18

Please help with number 1
bezimeni [28]

Answer:

19.0681

Step-by-step explanation:

Given in the question that,

angle from ted to the dog = 60° with the ground

height of ted from the ground =  16ft

To find,

distance between dog and the door of ted's building

Considering the scenario make a right angle triangle:

<h3>By using pythagorus theorem:</h3>

Tan 40 = opposite / adjacent

Tan 40 = height / distance between dog and the door

Tan 40 = 16ft / x

x = 16 / tan40

x = 19.068057

x ≈ 19.0681 (nearest to thousand)

So, the dog need to walk 19.0681ft to reach the open door directly below Ted.
