Answer: 194,000,000

Step-by-step explanation:

Given : According to the U.S. Census Bureau, about 63% of Americans are adults (18 and over).

We can rewrite 63% as 0.63 [ ∵ we divide 100 to convert a percent into decimal]

The estimated population of U.S  in 2010= 308 million

We know that 1 million = 1,000,000

⇒The estimated population of U.S  in 2010= 308,000,000

Now, the number of American adults in 2010 will be :-

0.63\times308,000,000=194,040,000\approx194,000,000  [Roundedto the nearest hundred thousand]

hence, the approximate number of American adults in 2010= 194,000,000

Given the two expressions below: 1) 4x2 − 8x + 9 2) 3x2 + 2y + 6 Is the sum of the two expressions above a polynomial? Why or wh
Mkey [24]
Sum of polynomials are always polynomials.

Note that despite it's name, single constants, monomials, binomials, trinomials, and expressions with more than three terms are all polynomials.
For example,
0, π sqrt(2)x, 4x+2, x^2+3x+4, x^2-x^2, x^5+x/ π -1
are all polynomials.

What makes an expression NOT a polynomial?
Expressions that contain non-integer or negative powers of variables, rational functions, infinite series.
For example,
sqrt(x+1), 1/x+4, 1+x+ x^2/2!+x^3/3!+x^4/4!+...., (5x+3)/(6x+7)
are NOT polynomials.

Find the missing length indicated. Leave your answer in simplest radical form.
musickatia [10]

Answer:

1). x = 81

2). x = 84

Step-by-step explanation:

1). By applying geometric mean theorem in the given triangle,

   \frac{x}{18\sqrt{14}}= \frac{18\sqrt{14}}{56}

   56x = (18√14)²

   56x = 4536

   x = \frac{4536}{56}

   x = 81

2). By applying geometric mean theorem,

    \frac{x}{8\sqrt{21}}= \frac{8\sqrt{21} }{16}

    16x = (8√21)²

    16x = 1344

    x = \frac{1344}{16}

   x = 84
