Answer:
(a) 12∠0.1
(b) 3∠-0.1
(c) (1/3)∠-0.1
Step-by-step explanation:
In this answer, we will use the notation r∠φ to identify the "r-part" and the "φ-part" of your polar-form complex numbers.
Given: z = 3∠0.1
(a) 4z = 12∠0.1 . . . . . the r-part is multiplied by the scalar
(b) z* = 3∠-0.1 . . . . . the conjugate is formed by negating the angle
(c) 1/z = (1/3)∠-0.1 . . . . the reciprocal inverts the magnitude and negates the angle.

What are fit equations?Fitting an equation to data is finding a linear, quadratic, exponential, or any other sort of function whose graph includes, or comes as close as possible to, a given set of data in the form of ordered pairs. The relative predictive power of a model shows how accurately the model is related to the data.
The theoretical pattern best accounts for the relationships among variables in a data set. For example, a regression equation having the best fit to sample data is the one that minimizes differences between observed and predicted values.

Which of the following equations, represents the line with a slope of 2/3 and a y-intercept of 9?
1) y = 3/2x-9
2) y = 3/2x + 9
3) y = 2/3x = 9
4) y = 2/3x + 9
Step-by-step explanation:
Equation of line:
[tex]y = mx + c[/tex]
where m is the slope
and c is the y-intercept
given the information from the question,
m = 2/3 , c = 9
substituting the values in,
equation of the line is
[tex]y = \frac{2}{3} x + 9[/tex]
What is the slope and y-intercept of this line?
y=3x + 7
Answer:
the slope is 3 and the y-intercept is 7
Step-by-step explanation:
in slope-intercept form, y=mx+b, m = the slope, and b = the y-intercept
Hello there!
The equation of this line is written in slope-intercept form, which looks like so:
y=mx+b
Where
m is the slope (-1/2 for this line)
b is the y-intercept (7)

What is the better deal? 6 for $6.99 or 24 for $13.99
Answer:
24 for $13.99
Step-by-step explanation:
Find the cost of 1 for both deals.
6 for $6.99. Divide 6.99 with 6:
6.99/6 = 1.165
~$1.17 for one.
24 for $13.99. Divide 13.99 with 24:
13.99/24 = ~0.582
~$0.58 for one.
24 for $13.99 is the better deal, by ~59¢.

What is the answer for (a^2+12c)÷7b-1
Answer:
Step-by-step explanation:
Integer roots:
a = 6 n + 1, b = 7, c = -3 n^2 - n, n element Z
a = 6 n + 5, b = 7, c = -3 n^2 - 5 n - 2, n element Z
Derivative:
d/da(1/7 (a^2 + 12 c) b - 1) = (2 a b)/7
Indefinite integral:
integral(-1 + 1/7 b (a^2 + 12 c)) da = (a^3 b)/21 + (12 a b c)/7 - a + constant
