Answer:

Since:

a^2-2ab+b^2 = (a-b)^2

and

a^2+2ab+b^2 = (a+b)^2

We need to find value of * which is 2ab

In your equation = \sqrt{6.25}  = 2.5 and \sqrt{1/4} = 0.5\\Now 2ab = 2 * 2.5 * 0.5\\ = 2.5\\\\\\* = 2.5ab

Answer:

i

Step-by-step explanation:

i = \sqrt{-1}

i^2 = -1

i^3 = -i

i^4 = 1

(Make sure you know your exponent rules)

i^4^1 = i^4^0 * i = (i^1^0)^4 * i \\i^4 = 1 \\i^1^0 * i *1 \\i^1^0=1\\1*1*i=i

SOVA2 [1]

Answer:

  A)  R = 1900 -24t

  B)  1684 billion barrels

  C) 79.17 years

Step-by-step explanation:

<h3>A)</h3>

Reserves start at 1900 billion barrels and decrease by 24 billion barrels each year. The value for t=0 is 1900; the value for t=1 is 24 less.

  R = 1900 -24t

__

<h3>B)</h3>

For t=9, the reserves will be ...

  R = 1900 -24(9) = 1900 -216 = 1684 . . . . billion barrels

__

<h3>C)</h3>

The reserve will be 0 when ...

  0 = 1900 -24t

  24t = 1900 . . . . . add 24t

  t ≈ 79.17 . . . . divide by 24

Reserves will be gone in about 79.17 years.
