Answer:
480 feet.
Step-by-step explanation:
We are told that the function
models Jason's height above ocean measured in feet as a function of time and t is the time in seconds from jumping off.
To find the height of cliff we need to substitute t=0 in our given function as at t=0 we will get Jason's height above ocean which is same as the height of the cliff.
Upon substituting t=0 in our function we will get,



Since, the function gives Jason's height above ocean in feet, therefore, the cliff was 480 feet high.
7s + 20 = 4s -13
7s - 4s = -13 -20
3s = -33
s = -33/3
s = -11
So this is a BIDMAS question so first you do the division and multiplication so you do (15 x 18) + (12/3) + 9 and get 270 + 4 + 9 which you just add to get 283. Hope this helps :)
