Acube of aluminum floats in a container partially filled with mercury (a) both the aluminum and mercury are at 20.0 c. what fraction of the cube is above the surface of the mercury? (numeric answer.) (b) the temperature of both the aluminum and the mereury is raised to 350 °c. what fraction of the cube is above the surface of a mercury? (numeric answer. (c) if the aluminum cube were 0.01 m on a side when the temperature is 20.0 °c, what is the length of one side after the temperature has been raised to 350 °c? (numeric answer)

i don't understand. explain it clearly

i had this question and the answer was 3.15 miles.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

the rearrangement of particles in a physical change. hope this

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
