r = 3 + 3cos(θ) polar equation would best match the desired audible range of the microphone.

<h3>How do you know if an equation is polar?</h3>
  • Determine the kind of polar equation.
  • The polar equation has the shape of a limaçon, and is written as r = a - b cos.
  • We just need to assess the equation throughout the range [0, 1] and then reflect the graph about the polar axis because the equation passes the condition for symmetry to the polar axis.

<h3>What is a polar in math?</h3>
  • The polar coordinate system in mathematics is a two-dimensional coordinate system in which the distance from a reference point and the angle from a reference direction are used to identify each point's location on a plane.

<h3>What is the meaning of polar form?</h3>
  • In addition to the rectangular form, a complex number can also be represented in polar form.
  • Typically, we write complex numbers as z = x + iy, where I is an imaginary integer.
  • However, in polar form, complex numbers are modeled as a union of argument and modulus.

78 is 15% of what #?
nirvana33 [79]
1. 78 = 0.15x
    78 / 0.15 = x
    520 = x.....so 78 is 15% of 520

2. | 3x - 2 | = 8                               | x + 1 | = 1

3x - 2 = 8      -(3x - 2) = 8            x + 1 = 1          -(x + 1) = 1
3x = 8 + 2      -3x + 2 = 8             x = 1 - 1           -x - 1 = 1
3x = 10           -3x = 6                  x = 0                 -x = 2
x = 10/3           x = -2                                             x = -2

ur answer is : x = -2

3. 3y - 4x + 5 = 0
    3y = 4x - 5
      y = 4/3x - 5/3
   slope = 4/3
