AfilCa [17]3 years ago
4 0

Answer:

1 to 100,000

Step-by-step explanation:

Centimeters and kilometers are scales of the official unit of length in the SI, the meters.

In a meter there are 100 centimeters, and in a kilometer there are 1000 meters, so in a kilometer there are 1000(100)cm ⇒ 100,000cm

So the scale of 1 centimeter to 1 kilometer is:

1 to 100,000

Your bank is offering a savings account with a nominal rate of 1.5%, compounded continuously. If you deposit $1,000 in 2010, wha
Anastaziya [24]

Answer:

$1,161.83

1.51%

Step-by-step explanation:

Continuously compounded interest is:

A = Pe^(rt)

where A is the final amount,

P is the initial amount,

r is the rate per time,

and t is time.

Given P = 1000, r = 0.015, and t = 10:

A = 1000e^(0.015 × 10)

A = 1000e^(0.15)

A = 1161.83

The effective annual yield is the annually compounded rate needed to have the same yield after the same time.  For continuously compounded interest, he equation for effective annual yield is:

R = -1 + e^r

R = -1 + e^0.015

R = 0.0151

The effective annual yield is 1.51%.
