The vehicle traveling 60 mph is going 4 times as fast. the brakes must do an amount of work that's equal to the original kinetic energy. the brakes exert the same amount of force no matter what the case is, so the stopping distance will be four times as long for the car going 60 mph compared to the car going 30 mph.
Answer:
y = 4/5x - 9/5
Step-by-step explanation:
4x - 5y = 9 to solve for y you get it by itself.
-4x -4x minus 4x from both sides
-5y = - 4x + 9
/-5 /-5 Divide both sides by 5
y = 4/5x - 9/5 because -4/-5 is 4/5 and 9/-5 is - 9/5

The volume of a sphere can be calculated as
Where r is the radius of the sphere
We want to calculate half of the volume, then we must divide that volume by 2
Now we must find the radius of our sphere, the segment AB is the diameter of the sphere, and the radius is half od the diameter, then
Let's put it into our equation
The problem says to use
Then
Final answer:
The formula that can be used to calculate the volume of water inside the fish bowl is
