F,2f are two forces act on a particle and enclose between them an angle of measure alpha. the magnitude of their resultant equals=sqrt5×f×(m+1) and if the measure of the angle between them becomes (90- alpha) then the magnitude of the resultant will be= sqrt5×f×( m-1)
prove that tan alpha=m-2/m+2

Consider the function represented by the equation 1/2 j + 1/4 k equals 3 which shows the equation written in function notation with j as the independent variable

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
