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 two points where they end and the point where they start form a right triangle, one leg is 12, the other leg is 15, you need to find the hypotenuse.
use the Pythagorean theorem: 12²+15²=c²
c≈19
they are about 19 feet apart.
Today’s UV index is = 8
Erin will burn in = 15 minutes
Since, its given"The time it takes to burn without sunscreen multiplied by the SPF, or sun protection factor, is the time you can stay in the sun safely with sunscreen"
= 
So, Erin will be protected for 375 minutes.
Answer:
9.6 km
Step-by-step explanation:
Issa jogged 2/3 of the way home from school.
Then he was tired, so he walked the remaining 3200 m.
In other words, the remaining 3200 m is 1/3 of the way from school to home.
Let the distance from school to home be x. Therefore:
Therefore, from school to home he traveled 9600 m.
To put this is kilometres:
1000 m = 1 km
9600 m = 9600 / 1000 = 9.6 km
He traveled 9.6 km from school to home.
