The submarine is closest to the surface at 10 am. Think about the way negative numbers work
-10,-9,-8,-8,-6,-5,-4,-3,-2,-1,0 as you get closer to 0 the negatives decreases. We can assume in this scenario the surface is zero. Thus -99 would be closest because it is the smallest negative.
parallel lines never cross
but transversal lines do cross
I hope this helps
have a great day
Answer:
The ball will take 4.05 seconds to hit the ground.
Step-by-step explanation:
we have
This is a quadratic equation (vertical parabola) open down
The vertex is a maximum
we know that
The ball hit the ground when h=0
Solve the quadratic equation
For h=0
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
---> the time cannot be a negative number
therefore
The ball will take 4.05 seconds to hit the ground.
