Answer: Third investment is the least simple interest and Second investment is the most earned simple interest.

Step-by-step explanation:

Since we have given that

Investment of $3,000 at 5% simple interest for 20 years .

Simple interest would be

$\dfrac{3000\times 5\times 20}{100}\\\\=\$3000$

Investment of $1,000 at 16% simple interest for 20 years

Simple interest would be

$\dfrac{1000\times 16\times 20}{100}\\\\=\$3200$

Investment of $3,000 at 16% simple interest for 2 years.

Simple interest would be

$\dfrac{3000\times 16\times 2}{100}\\\\=\$960$

Hence, Third investment is the least simple interest and Second investment is the most earned simple interest.

Phantasy [73]

Answer:

Step-by-step explanation:

$\frac{5+4i}{-3-2i}\\\\\mathrm{Apply\:complex\:arithmetic\:rule}:\\\\\quad \frac{a+bi}{c+di}\:=\:\frac{\left(c-di\right)\left(a+bi\right)}{\left(c-di\right)\left(c+di\right)}\:=\:\frac{\left(ac+bd\right)+\left(bc-ad\right)i}{c^2+d^2}\\\\a=5,\:b=4,\:c=-3,\:d=-2\\\\=\frac{\left(5\left(-3\right)+4\left(-2\right)\right)+\left(4\left(-3\right)-5\left(-2\right)\right)i}{\left(-3\right)^2+\left(-2\right)^2}\\\\Refine\\=\frac{-23-2i}{13}\\\\$
