(a+b)^2=(a^2+b^2), so 2000((1^21)+(0.054^21)) then you simplify the obviose 1^21, 2000(1+(0.054^21)) then solve 0.054^21,

2000(1+(3.78*10^-31)) then distribute the 2000, 2000+(2000*3.78*10^-31) then you solve the parenthathees,

2000+(7.56*10^-28) then add. then your done. ps the answer is 2000 suprisingly. thats if your suposed to round to the neerest thouthandth of milionth, so on.

What?

CPhill: I think something is WRONG with one of our two solutions !!!

P.S. Note that Hungary population is DECREASING by 2% per year!

Just set the equations equal  and solve for t

9.04 (1.05)^t   =  10.1(0.98)^t        divide both sides by 9.04

(1.05)^t  =  (10.1 / 9.04) (0.98)^t     divide both sides by (0.98)^t

(1.05)^t / ( 0.98)^t  =  (10.1 / 9.04)     and we can write

(1.05 / 0.98 )^t  =  (10.1 / 9.04)         take the log of both sides

log (1.05 / 0.98)^t  =  log ( 10.1 / 9.04)     and by a log property

t * log ( 1.05 / 0.98)  = log (10.1 / 9.04)    divide both sides by log (1.05/0.98)

t  =   log (10.1 / 9.04) /  log ( 1.05 / 0.98)  ≈  1.607 years ≈  2007

Solve for t over the real numbers:
1.05^t = 1.11726 0.98^t

Take the natural logarithm of both sides and use the identities log(a b) = log(a) + log(b) and log(a^b) = b log(a):
0.0487902 t = 0.110876 - 0.0202027 t

Add 0.0202027 t to both sides:
0.0689929 t = 0.110876

Divide both sides by 0.0689929:
Answer: | t = 1.60707 Years

In computing, the modulo operation finds the remainder after division of one number by another (sometimes called modulus). Given two positive numbers, a (the dividend) and n (the divisor), a modulo n (abbreviated as a mod n) is the remainder of the Euclidean division of a by n.

When two chords intersect in a circle, the products of their respective segments are equal.....so...

15 * 25  = 30 * x       divide both sides by 15

25 =  2x    divide both sides by 2

12.5   = x

arctan 1 = ?

The arctangent is the inverse tangent function.

Since

tan π/4 = tan 45º = 1

The arctangent of 1 is equal to the inverse tangent function of 1, which is equal to π/4 radians or 45 degrees:

arctan 1 = tan-1 1 = π/4 rad = 45º

well i guess the calculator here stinks

On the calculator here? Press "2nd" key first. You should see "asin", "acos" and "atan", which are the inverse functions of sin, cos and tan.

the surface area of earth is 510072000km^2 and the surface area of jupiter is 6.21795 x 1010 km^2. the surface area of jupiter is greter then the surface area of the earth,calculate how many times greater? (in standard form)

Just divide: [6.21795 x 10^10] / 510,072,000=~122 times bigger.

@CPhill, would you mind helping me start this?
