Answer: $11,233.67, $81,661.70
Step-by-step explanation:
[tex]A = Pe^{rt}[/tex] where A is the total amount earned, P is the principal amount invested, r is the interest rate, and t is the time it is invested
What do we know?
A = unknown
P = 10,000
r = .07 (converted 7%)
t = 3 years
[tex]A = Pe^{rt}[/tex]
[tex]A = 10,000e^{(.07)(3)}[/tex]
[tex]A = 10,000e^{.21}[/tex]
A = 10,000(1.2333678)
A = 11,233.3678
rounded to the nearest penny, A = 11,233.37
[tex]A = Pe^{rt}[/tex]
[tex]A = 10,000e^{(.07)(30)}[/tex]
[tex]A = 10,000e^{2.1}[/tex]
A = 10,000(8.16617)
A = 81661.70

Answer: [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
[tex]ln\sqrt[5]{e^{2} }[/tex]
= [tex]ln(e^{\frac{2}{5} } )[/tex]
= [tex]\frac{2}{5}[/tex]
