Determine the average rate of change of the function y(t) = .5 t 2 + 56 t + -55 between x and x + Dx.[.5(x+dx)^2 + 56(x+dx) - 55 -.5x^2 - 56x + 55]/dx

=[.5x^2 + .5(2xdx) + .5dx^2 + 56x + 56dx -.5x^2 - 56x]/dx

= (xdx + .5dx^2 + 56dx)/dx

= x + .5dx + 56

What are the growth rate, growth factor and principal function P(t) for an initial investment of $ 760 which is compounded annually at 10% interest?

G.R = .1

G.F = 1 + .1 = 1.1

Principle = $760

&#Very good work. Let me know if you have questions. &#
