F=ir^t, f=final amount, i=initial amount, r=common ration or "rate", t=times common ration is applied or "time", in this case:

1200=1000r^2  divide both sides by 1000

1.2=r^2  take the square root of both sides

1.2^(1/2)=r so the equation is:

f=1000(1.2)^(t/2), so in 13 hours

f=1000(1.2)^(13/2)

f=1000(1.2)^(6.5)

f≈3271 bacteria (to the nearest whole number)

malfutka [58]

Answer:

A.  2 distinct roots.

Step-by-step explanation:

2x^2 + 8x + 3 = 0

Finding the discriminant:

b^2 - 4ac = 8^2 - 4 * 2 * 3

=  64 - 24

= 40

The discriminant is positive but not a perfect square

So there are 2 distinct ,real, irrational roots.

Armen received $2000 as an interest for term deposit of 2 years. How much money did he deposit, if the annual interest was 8%?
suter [353]

Answer: $12,500

Step-by-step explanation:

We want to find how much he deposited annually, so we divide 2000 by 2 to get 1000 for 1 year. 1000 is 8 percent of what we need to find, so if we multiply 1000 by 100/8, we get $12,500 as our answer.
