TABLE OF CONTENTS

Step 1. Given information

$5^{x + 3} = \frac{1}{5}$

Step 2. Calculations

$5^{x + 3} = \frac{1}{5} 5^{x + 3} = 5^{- 1} i f a^{u} = a^{v} t h e n u = v x + 3 = - 1 x = - 4$

Step 3. Graphing solution

Graph $y = 5^{x + 3}$ and y =1/5 intersect at (-4,0.2)

Hence the required solution set is {-4}.

Vehicle Stopping Distance Taking into account reaction time, the distance $d$ (in feet) that a car requires to come to a complete stop while traveling $r$ miles per hour is given by the function

localid="1646198784356" $d (r) = 6.97 r - 90.39$

a. Express the speed $r$ at which the car is traveling as a function of the distance localid="1646198792401" $d$ required to come to a complete stop

b. Verify that localid="1646198797631" $r = r (d)$ is the inverse of localid="1646198802104" $d = d (r)$ by showing that localid="1646198806352" $r (d (r)) = r$ and localid="1646198811055" $d (r (d)) = d$

c. Predict the speed that a car was traveling if the distance required to stop was localid="1646198818232" $300$ feet.

$d (r (d)) = d$
