Answer:
False
Explanation:
According to USA today "Though nearly 60% of the 18 to 21 year olds surveyed said they have a job, and 70% of the 22 to 26 year olds said the same, many seem to rely on mom and dad to fund non-essential expenses. Nearly 75% of the 18 to 21 year olds and more than 40% of 22 to 26 year olds said their parents pay their monthly cell phone bill. Just 54% of 22 to 26 year olds own or lease their own car; and 43% of 22 to 26 year olds are living at home with their parents."
Answer:
In a closed system, the total energy is conserved or remains the same as energy transformations take place.
Explanation:
The law of conservation of energy states that energy cannot be created or destroyed but can be transformed from one form to another.
This law of conservation of energy applies only to a closed system. A closed system is a system which does not exchange energy with its surroundings. All forms of energy conversions occurring within a closed system does not result in an increase or decrease of the total energy of the system, rather, energy remains constant. For example, the universe is a closed system in that all forms of energy conversions occurs within it and energy is not exchanged with an external environment. However, the earth is not a closed system as some of the energy it receives from the sun can be radiated out into space. Since it's an open system, its total energy can change.
Explanation:
It is given that,
= -40 mi/h, = -40 mi/h
The negative sign indicates that x and y are decreasing.
We have to find 
. Equation for the given variables according to the Pythagoras theorem is as follows.
Now, we will differentiate each side w.r.t 't' as follows.
or, 
So, when x = 4 mi, and y = 3 mi then z = 5 mi.
As,
= 
= 
= 52
Thus, we can conclude that the cars are approaching at a rate of 52 mi/h.
