Ellie is driving at a speed of 55 miles per hour. let h represent the number of hours that ellie drive at this speed. write an algebraic expression to represent the number of miles that ellie drives during this time

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f left parenthesis x right x squared over 2 left parenthesis 1 minus x right parenthesis endfraction , where x is a number between 0 and 1 known as the traffic intensity. find the rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities (a) xequals0.3 and (b) xequals0.6.

Simplify the expression. -2/5(10+15m-20n)

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30
