m_a_m_a [10]

Answer:

  • 65.312 inches
  • 326.56 inches
  • 1959.36 inches

Step-by-step explanation:

<h3>Given</h3>
  • d = 20.8 inches
<h3>To find</h3>
  • Travel in 1, 5, 30 rotations
<h3>Solution</h3>

<u>Circumference of the wheel is equal to one full rotation</u>

  • C = πd = 3.14*20.8 = 65.312 inches
  • 5C = 5*65.312 = 326.56 inches
  • 30C = 30*65.312 = 1959.36 inches

Find the surface area of the pyramid. the surface area of the pyramid is __in squared.
iVinArrow [24]

Answer:

561.08in^{2}

Step-by-step explanation:

S A = lw + l \sqrt{(\frac{w}{2})^{2}  + h^{2}  } + w \sqrt{(\frac{l}{2})^{2} + h^{2}  }

SA = 14(14) + 14 \sqrt{(\frac{14}{2})^{2} + 11^{2}  }+ 14 \sqrt{(\frac{14}{2})^{2} + 11^{2}  } = 561.08in^{2}

Find the horizontal and vertical asymptotes of​ f(x). ​f(x) equals = StartFraction 6 x Over x plus 2 EndFraction 6x x+2 Find the
miss Akunina [59]

Answer:

The horizontal asymptote can be described by the line y = 6

The vertical asymptote can be described by the line x = -2

Step-by-step explanation:

* <em>Lets the meaning of vertical and horizontal asymptotes</em>

- <u><em>Vertical asymptotes</em></u> are vertical lines which correspond to the zeroes

  of the denominator of a rational function

- <u><em>A horizontal asymptote</em></u> is a y-value on a graph which a function

 approaches but does not actually reach

- If the degree of the numerator is less than the degree of the

 denominator, then there is a horizontal asymptote at y = 0

- If the degree of the numerator is greater than the degree of the

 denominator, then there is no horizontal asymptote

- If the degree of the numerator is equal the degree of the denominator,

 then there is a horizontal asymptote at y = leading coefficient of the

 numerator ÷ leading coefficient of the denominator

* <em>Lets solve the problem</em>

∵ f(x)=\frac{6x}{x+2}

∵ The numerator is 6x

∵ The denominator is x + 2

∴ The numerator and the denominator have same degree

∵ The leading coefficient of the numerator is 6

∵ The leading coefficient of the denominator is 1

∴ There is a horizontal asymptote at y = 6/1

∴ <em>The horizontal asymptote can be described by the line y = 6</em>

- Put the denominator equal zero to find its zeroes

∵ The denominator is x + 2

∴ x + 2 = 0

- Subtract 2 from both sides

∴ x = -2

∴ <em>The vertical asymptote can be described by the line x = -2</em>
