this circle has a diameter of 5 inches which of these measurements is closest to the circumference of the circle 15.7 7.85 31.4
nirvana33 [79]

Answer:

The closest measurement is 15.7

Step-by-step explanation:

The formula for circumference is 2\pi r

The diameter is double the radius, so to get the radius we divide by 2.

5 divided by 2 is 2.5

Knowing "r" is 2.5 we can plug that into our equation and solve.

2 · \pi · 2.5 ≈ 15.71

The closest measurement is 15.7

What is the difference?
Serhud [2]

Answer:

The option \frac{(x+5)(x+2)}{x^3-9x} is correct

The difference of the given expression is

\frac{2x+5}{x^2-3x}-(\frac{3x+5}{x^3-9x})-({\frac{x+1}{x^2-9})=\frac{(x+5)(x+2)}{x^3-9x}

Step-by-step explanation:

Given expression is \frac{2x+5}{x^2-3x}-(\frac{3x+5}{x^3-9x})-({\frac{x+1}{x^2-9})

To find the difference of the given expression as below :

\frac{2x+5}{x^2-3x}-(\frac{3x+5}{x^3-9x})-({\frac{x+1}{x^2-9})

=\frac{2x+5}{x(x-3)}-(\frac{3x+5}{x(x^2-9)})-({\frac{x+1}{x^2-9})

=\frac{2x+5}{x(x-3)}-(\frac{3x+5}{x(x^2-3^2)})-({\frac{x+1}{x^2-3^2})

=\frac{2x+5}{x(x-3)}-(\frac{3x+5}{x(x-3)(x+3)})-({\frac{x+1}{(x-3)(x+3)})  

( using the formula a^2-b^2=(a+b)(a-b) )

=\frac{2x+5(x+3)-(3x+5)-x(x+1)}{x(x-3)(x+3)}

=\frac{2x^2+6x+5x+15-3x-5-x^2-x}{x(x-3)(x+3)} (adding the like terms)

=\frac{x^2+7x+10}{x(x^2-9)} ( by factoring the quadratic polynomial )

=\frac{(x+5)(x+2)}{x^3-9x}

Therefore \frac{2x+5}{x^2-3x}-(\frac{3x+5}{x^3-9x})-({\frac{x+1}{x^2-9})=\frac{(x+5)(x+2)}{x^3-9x}

Therefore the difference of the given expression is

\frac{(x+5)(x+2)}{x^3-9x}

Therefore option \frac{(x+5)(x+2)}{x^3-9x} is correct
