Answer:
P = $ 766.28
Explanation:
present value = ?
Future value = $ 2000
time = 5 years
compounded annually at the rate of = 10 %
2000 = P + 1.61 P
2.61 P = 2000
P = $ 766.28
hence, the present value of amount invested to get the future value of $2000 is equal to P = $ 766.28

Explanation:
Given that;
A fluid flows along the x axis with a velocity given by V = (xt) i ˆ, where x is in feet and t in seconds. (a) Plot the speed for 0 ≤ x ≤ 10 ft and t = 3 s. (b) Plot the speed for x = 7 ft and 2 ≤ t ≤ 4 s. (c) Determine the local and convective acceleration. (d) Show that the acceleration of any fluid particle in the flow is zero. (e) Explain physically how the velocity of a particle in this unsteady flow remains constant throughout its motion.
