The height of the video game is 4.5
Answer:
kinectic + electric = internal
Step-by-step explanation:
Internal energy U of a system or a body with well defined boundaries is the total of the kinetic energy due to the motion of molecules and the potential energy associated with the vibrational motion and electric energy of atoms within molecules. Internal energy also includes the energy in all the chemical bonds.
To write 3.40 as a fraction you have to write 3.40 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
3.40 = 3.40/1 = 34/10
And finally we have:
3.40 as a fraction equals 34/10 simplified we get: 3 2/5
To find the inverse function of a function, you rearrange for the x term (could be some other letter) and then swap the function and the x at the end. For example,
and so,
For part 3 we have
and hence,
Can you do part 4 on your own?
