Graph A its the beat answer
I have a simple but slightly time consuming way of doing this. Find 30% of 100 double it and then find 30% of 25, add the two together... In this case 60 + 7.5. After you do that subtract that number from 225. So subtract 67.5 from 225 and there is your answer. Your answer is 157.5
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.
The values that make the denominator zero are not in the domain.
x²- 4x - 12 = 0
(x - 6)(x + 2) = 0
Answer: 6, -2
