A rock is thrown into a pool 72 inches deep. The rock sinks at a rate of 4 inches per second (s). The rock's height (h) above
the bottom of the pool is given by the equation h = 72 - 4s
After how many seconds will the rock be half way to the
bottom?

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
