A drone's altitude hhh in metres is related to the time ttt in seconds after it passes a reference point by the function
h(t)=7t−363,t≥6 h(t) = \frac{7t - 36}{3}, \quad t \ge 6 h(t)=37t−36,t≥6Solve the equation
h(t)=h−1(t) h(t) = h^{-1}(t) h(t)=h−1(t)Select your answer from the options below:
t=5.1t = 5.1t=5.1
t=6t = 6t=6
t=9t = 9t=9
t=12t = 12t=12
