Sasha invests $1000 that earns 8% interest compounded annually. write a function that describes the value, v, of the investment after t years.

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 -9p - 17 =10 a -3 b. 16 c. 18 d -16
