Answer:
$621.08
Step-by-step explanation:
The formula for the amount (A) resulting from principal P being invested at rate r continuously compounded for period t is ...
A = Pe^(rt)
Filling in the given numbers and doing the arithmetic, we get ...
A = $400e^(0.055·8) ≈ $621.08
Answer:
113.1cm
Step-by-step explanation:
area= 
r²
r= half the diameter r=6
a=6²
a=36
a=113.1 cm
9514 1404 393
Answer:
29.15 in
Step-by-step explanation:
The area of a rectangle is given by the formula ...
A = LW
Filling in the given information, we can find the missing side length.
297 in² = (27 in)h
h = (297 in²)/(27 in) = 11 in
The length of the diagonal can be found from the Pythagorean theorem.
d² = 27² + 11² = 729 +121 = 850
d = √850 = 5√34 ≈ 29.15476
The length of the diagonal is about 29.15 inches.
