If a 5,000 investment earn $1,575 interest over over 18 years what is the annual interest rate
ss7ja [257]

Answer:

I = 1575 / 5000 = 31.5 % interest on investment

(1 + i)^18 = 1.315      where i interest is earned per year

One can use logs or

1 + i = 1.315^1/18  = 1.0153

So the annual interest rate is .0153   or 1.53%

Or

5000 (1 + i)^18 = 6575

(1 + i)^18 = 1.315

18 log (1 + i) =  log 1.315

log (1 + i) =  .006607

1 + i = 1.0153

i = .0153 = 1.53%

What type of conducting medium has the highest conductivity?
andreyandreev [35.5K]
I can't really answer this question without giving me any limits to the possibilities of the answers. However, I found a similar problem with a given set of choices. I think the answer is plasma. The medium that has the highest conductivity must be electric or ionized in nature. Since plasma is a very hot ionized gas, then it would be the most conductive out of all the choices.

What is the mass of a large ship that has a momentum of 1.60x10^9 kg*m/s and is moving at a velocity of 10m/s?
Elden [556K]

Answer:

160000000 kg.

Explanation:

p=mv

p=1.6x10^9

v=10m/s

rearrange and substitute:

(1.6x10^9)=m(10)

m=(1.6x10^9)/10

m= 1.6x10^8 kg.
