Answer:
x = 0
Step-by-step explanation:
Since the product is not equal zero, we need to multiply both parenthesis first:
Add 27 from both sides:
Factor out:
Apply the zero product:
The solutions of the equation are and
.
We can conclude that the correct answer is x = 0.
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.
