Answer:

2.3%

Step-by-step explanation:

For continous compound interest

$A=Pe^{it}$

Where A is final value, P is initial investment, i is interest rate in decimal and t is period.

The time will be 30-18=12 years

Substituting $14000 for A, $7000 for P and 12 years for t

$14000=7000e^{12i}\\e^{12i}=2$

Introducing natural logarithms on both sides then 12i=ln 2

Making i the subject of formula then

i=ln 2 ÷12=0.05776226504666

The percentage rounded off will be 5.7% p.a

EleoNora [17]

Answer:

$15 \sqrt[3]{2}$

Step-by-step explanation:

${(27 \times 250)}^{ \frac{1}{3} } = {(27 \times 125 \times 2)}^{ \frac{1}{3} } \\ = {27}^{ \frac{1}{3} } \times {125}^{ \frac{1}{3} } \times {2}^{ \frac{1}{3} } \\ = \sqrt[ 3]{27} \times \sqrt[3]{125} \times \sqrt[3]{2} \\ = \sqrt[3]{ {3}^{3} } \times \sqrt[3]{ {5}^{3} } \times \sqrt[3]{2} \\ = 3 \times 5 \times \sqrt[3]{2} \\ = 15 \sqrt[3]{2}$
