The perimeter of a triangle is 28 feet. the sides of the triangle measure 10 feet, 9 feet, and x feet. write and solve an equation to find the length of the missing side.

Which graph represents the following piecewise defined function?

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.

If x is 6, then 7x= a. 13 b. 42 c. 42x d. 76
