Evaluate without using a calculator sin(90-x)cos(180-x)+tanx. cos(-x)sin(180+x)​

What properties allow transformation to be used as a problem solving tool

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.

Which of the following quartic functions has x = –1 and x = –2 as its only two real zeroes?
