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.

Answer:
36 years old (jim)
Step-by-step explanation:
looks like a good ol' word problem!
first, if you don't know what to do, always assign variables
Jim's age: x+9
June's age: x
Alex's age: x-8
we know the sum of their ages which is 82
so, x+9+x+x-8=82
simplify
3x+1=82
3x=81
x=27, but we're not done yet
Now we know x
jim: 36
june: 27
Alex: 21
so the oldest is jim at 36
The formula that models this is
Where R is the number of rabbits and t is the number of years that have passed.
Y axis ofc A & B are the boxes
Answer:
42
Step-by-step explanation:
It's just a distribution property where the given value of each variables (a, b, c, d) are being distributed to the given equation:
7a2-3ac+d2
7(2)(2) - 3(2)(-3) + (-2)(2)
28 + 18 - 4 = 42
