Solve the Problem w(x)=1.17x+1,225w ( x ) = - 1.17 x + 1,225

Question 51

Multiple Choice

Solve the problem.
-Based on data from a hurricane, the function defined by w(x) =1.17x+1,225w ( x ) = - 1.17 x + 1,225 gives the wind speed w(x) w ( x ) (in mph) based on the barometric pressure xx (in millibars, mb) . Write a function representing the inverse of ww and interpret its meaning in context.


A) w1(x) =1,225x1.17w ^ { - 1 } ( x ) = \frac { 1,225 - x } { 1.17 }
B) w1(x) =x1,2251.17w ^ { - 1 } ( x ) = \frac { x - 1,225 } { 1.17 } ; The inverse gives the barometric pressure w1(x) w ^ { - 1 } ( x ) for a given wind speed.
C) w1(x) =1,225x1.17w ^ { - 1 } ( x ) = \frac { 1,225 - x } { 1.17 } ; The inverse gives the barometric pressure w1(x) w ^ { - 1 } ( x ) for a given wind speed.
D) w1(x) =x1,2251.17w ^ { - 1 } ( x ) = \frac { x - 1,225 } { 1.17 } ; The inverse gives the wind speed w1(x) w ^ { - 1 } ( x ) for a given barometric pressure.
