The table shows the balance of a money market account over time. write a function that represents the balance y(in dollars) after t years.

Is the power produced directly proportional to the wind speed, give reasons for your answer?

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
