Answer:

Step-by-step explanation:

The formula for the account balance from continuously compounded interest at annual rate r for t years is ...

A = Pe^(rt) . . . . P = principal invested

A = 8820e^(0.05·3) ≈ 10,247.38 . . . continuous compounding

The formula for the account balance from interest compounded semiannually at annual rate r for t years is ...

A = P(1 +r/2)^(2t)

A = 8820(1 +.05/2)^(2·3) ≈ 10,228.50 . . . semiannual compounding

Continuous compounding earns more.

Speed is the rate of distance over time.

The speed of the boat is 13mph south-west

Given

$v_1 = 12mph$ --- west

$v_2 = 5mph$ -- south

The speed is illustrated with the attached image

Because both speeds act at a diagonal, the speed (v) of the boat is calculated using Pythagoras theorem as follows:

$v^2 = 12^2 + 5^2$

$v^2 = 144 + 25$

$v^2 = 169$

Take square root

$v = \sqrt{169$

$v = 13$

Hence, the speed of the boat is 13mph south-west
