$$\begin{array} { l } {\text {Suppose } f \text { and } g \text { are functions that are differentiable} } \\ { \text {at } x = 1 \text { and that } f ( 1 ) = 2 , f ^ { \prime } ( 1 ) = - 1 , g ( 1 ) = - 2 , \text { and } } \\ { g ^ { \prime } ( 1 ) = 3 . \text { Find the value of } h ^ { \prime } ( 1 ) \text { . } } \end{array}$$

$$h ( x ) = \frac { x f ( x ) } { x + g ( x ) }$$

convert the polar equation to rectangular form θ = 5π/6

When Neil Simon opens a new play, he has to decide whether to open the show on Broadway or Off Broadway. For example, in his play London Suite, he decided to open it Off Broadway. From information provided by Emanuel Azenberg, his producer, the following equations were developed:

$$\begin{array}{lll} 43,500x & -y & =1,295,000\\ 27,000x & -y & =440,000 \end{array}$$

where x represents the number of weeks that the show has run and y represents the profit or loss from the show (first equation is for Broadway and second equation is for Off Broadway). Source: The Mathematics Teacher. (a) Solve this system of equations to determine when the profit/loss from the show will be equal for each venue. What is the profit at that point? (b) Discuss which venue is favorable for the show.
