Answer:
4X + 5
Step-by-step explanation:
We start with the unknown number, X.
Doubling the number :
⇒ 2 × X
⇒ <u>2X</u>
<u />
Adding 5 to double the number :
⇒ 2(2X) + 5
⇒ 4X + 5
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.

2x-7+-6x-3 2x+-6x=-4x
-4x-10=0
-5/2 is the answer
Use logarithms to solve for a.
Similarly, for b and x.
Factorize 150:
150 = 2 • 3 • 5²
Then we can expand log₃(150) using the product-to-sum and exponent property,
