Answer:
$12000 at 5% for 8 years
Step-by-step explanation:
The amount in an account earning continuous interest is given by ...
A = Pe^(rt)
Then the interest earned is ...
I = P(e^(rt) -1)
For the two accounts, the interest earned is ...
I = 12000(e^(.05·8) -1) = 12000(0.491825) = 5901.90
I = 9000(e^(0.065·7) -1) = 9000(0.576173) = 5185.56
The $12000 account earns more interest, primarily because of the larger amount invested.
Answer:
Volume = 66 cm³
Step-by-step explanation:
Area of the oblique triangular prism = Area of the triangular base × Vertical height from the base
From the figure attached,
Area of the triangular base =
=
= 6 cm²
Vertical height of the given oblique prism = 11 cm
Volume of the given oblique prism = 6 × 11
= 66 cm³
