Answer:

Step-by-step explanation:

This seems more like a physics questions, but i'll help you  :P

the circle is 8 feet across or a radius of 4 feet

circumference of the circle is 2\pir  = 25.132741 feet

it's going around 420 times a minute

420 * 25.132741 = 10555.75132 feet per minute

10,555.75

Find g(2/3). Simplify your answer. Type an exact answer, using radicals as needed).
ki77a [65]
The solution is 2sqrt77/77.  You just fill in 2/3 for the x's. When you do that, you do that you get (2/3)/sqrt(9-[2/3]^2) which, simplified, is (2/3)/sqrt(9-[4/9]). Now use the common denominator under the radical of 9 to get (2/3)/sqrt([81-4]\9).  Simplifying even further gives you (2/3)/([sqrt(77)]/3). Now do that division by multiplying 2/3 by the reciprocal of ([sqrt(77)]/3) to get 2/sqrt77.  I rationalized the denominator to get that result up there.

Which of the following is the quotient of the rational expressions shown here? x/x-1 / 1/x 1.
WINSTONCH [101]

The quotient of the rational expressions is \rm \dfrac{x^2-x}{x-1}.

<h3>Given that</h3>

Rational Expression; \rm \dfrac{x}{x-1} ÷\rm \dfrac{1}{x+1}

<h3>We have to determine</h3>

Which of the following is the quotient of the rational expressions shown here?

<h3>According to the question</h3>

Rational Expression; \rm \dfrac{x}{x-1} ÷\rm \dfrac{1}{x+1}

Then,

The quotient of the rational expressions is,

\rm \dfrac{x}{x-1} ÷\rm \dfrac{1}{x+1}

\rm =\dfrac{x}{x-1} \times \dfrac{x+1}{1}\\&#10;\\ =\dfrac{x(x-1)}{x\times 1}\\&#10;\\&#10;=\dfrac{x^2-x}{x-1}

Hence, The quotient of the rational expressions is \rm \dfrac{x^2-x}{x-1}.
