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.

Answer:
The quadratic equation is X^2 -4X-60=0
Step-by-step explanation:
You solve by using the relation
X^2-(Sum)X + Product
which is (-6+10)X +(-6×10)
=X^2 -4X -60
X^2 +6x -10x -60 =0
(X^2+6x)-(10x-60)
=X(X+6)-10(x+6)
=(X-10)(X+6) =0
x-10=0. and x+6=0
x=10. x=-6
Therefore the quadratic equation is given by x^2 -4x -60
-3x+4=15
-3x=15-4
-3x=11
x= -11/3
4(-11/3)-y= -19
-44/3-y= -19
-y= -19+44/3 multiply by (-1)
y=19-44/3
y=19•3/3-44/3
y=57/3-44/3
y=13/3
(x,y)=(-11/3, 13/3)
Jeremy rows 1/3 of a mile in 1/4 of an hour.
The unit rowing rate is
1/3 mile ÷ 1/4 hour
= (1/3)*(4/1) miles/hour
=4/3 miles/hour
=1.333 miles/hour (approx.)
