The cars (seats) of a Ferris wheel are positioned 74 feet from its center. If the Ferris wheel makes 4 revolutions every 4 minutes, find the linear speed of one of the cars in feet per second. Round your answer to the nearest hundredth

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

Solve the equation using the given values: x= -2.5; y= -7.51. 2xy + 2x²

Which of the following is the graph of y= square root -x-3
