Answer:
see below
Step-by-step explanation:
y = 5x-3
Let x = -2 y = 5(-2) -3 = -10 -3= -13
Let x = -1 y = 5(-1) -3 = -5-3 = -8
Let x = 0 y = 5(0) -3 = 0-3 = -3
Let x = 1 y = 5(1) -3 = 5-3 = 2
Let x = 2 y = 5(2) -3 =10-3 = 7
Answer:
$30.62
Step-by-step explanation:
12% of 40 is 4.8
(10% is 4, 2% is 0.8)
40- 4.8= 35.2
13% of 35.2 is 4.576
(10% is 3.52, 3% is 1.056)
35.2- 4.576= 30.624
then rounded to 2 decimal places
30.62
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.

Half-life is a measure of how long it takes half of a given measurement of an isotope to be converted to another element. After one year, half of the isotope will be present.
Year 1: 88/2 = 44g
Year 2: 44/2 = 22g
Answer:
first one
Step-by-step explanation:
Because the coefficient of x is 3 and coefficient of y is-7
