A graph of x vs. t4, with x on the vertical axis and t4 on the horizontal axis, is linear. Its slope is 51 m/s4 and its vertical-axis intercept is 8 m. Write an equation for x as a function of t.

Vector A has a magnitude of 10 units and makes an angle of 30 degrees counterclockwise from the positive x-axis. Vector B has a magnitude of 25 units and makes an angle of 50 degrees clockwise from the positive x-axis. What is the magnitude of  A + B?

The x component of vector A is 8.7 units, and its y component is -6.5 units. What is the magnitude of A?
