Astudent solving a physics problem to find the unknown has applied physics principles and obtained the expression: μkmgcosθ=mgsinθ−ma, where g=9.80meter/second2, a=3.60meter/second2, θ=27.0∘, and m is not given. which of the following represents a simplified expression for μk? a student solving a physics problem to find the unknown has applied physics principles and obtained the expression: , where , , , and is not given. which of the following represents a simplified expression for ? gsinθ−agcosθ to avoid making mistakes, the expression should not be simplified until the numerical values are substituted. tanθ− ag the single equation has two unknowns and cannot be solved with the information given.

mistakes are ok

gravity

explanation:

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 .

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
