Using Models Use the model given to answer the questions about the object or process being modeled. An ocean diver models the pressure $P$ ( in $\mathrm{lb} / \mathrm{in}^{2} )$ ) at depth $d$ (in ft) by $$P=14.7+0.45 d$$ (a) Make a table that gives the pressure for each 10 -ft change in depth, from a depth of 0 ft to 60 $\mathrm{ft}$ . (b) If the pressure is $30 \mathrm{lb} / \mathrm{in}^{2},$ what is the depth?

An ocean diver models the pressure $P (\text { in } 1 b / \text { in }^{2} \text { ) at depth } d$ (in ft) by $$P=14.7+0.45 d$$a. Make a table that gives the pressure for each $10-\mathrm{ft}$ change in depth, from a depth of $0 \mathrm{ft}$ to 60 ft.. b. If the pressure is $30 \mathrm{lb} / \mathrm{in}^{2},$ what is the depth?
Use the model given to answer the questions about the object or process being modeled. An ocean diver models the pressure $P\left(\text { in } \operatorname{lb} / \mathrm{in}^{2}\right)$ at depth $d$ (in ft) by $$ P=0.45 d+14.7 $$ (a) Find the pressure $P$ at a depth of 180 $\mathrm{ft}$ . (b) Find the pressure $P$ at a depth of 330 $\mathrm{ft}$ .
