Since the rate is constant, the growth of the height of the helicopter follows a linear pattern. The helicopter has an initial quota of 40ft, so that would be the constant term. The linear terms's coefficient is the rate of growth, so 21 ft/s. So, if
is the number of seconds passed from when the observation started, we have
![h(t) = 40+21t](https://tex.z-dn.net/?f=%20h%28t%29%20%3D%2040%2B21t%20)
Which means that, if
, the height is
![h(45)=40+21\cdot45 = 40+945=985](https://tex.z-dn.net/?f=%20h%2845%29%3D40%2B21%5Ccdot45%20%3D%2040%2B945%3D985%20)
