What is the rectangular form of z= 40(cos(7pi/6)+ i sin(7pi/6))
a. z= 20-20i rt3
b. z= 20rt3 -20 i
c. z= -20rt3 -20 i
d. z= -20-20 i rt3
Answers
Answer:
C. [tex]z = -20\sqrt{3}-i\,20[/tex]
Step-by-step explanation:
The rectangular form of a complex number is represented by the following formula:
[tex]z = a+i\,b[/tex] (1)
Where each coefficient can be determined as function of the polar components:
[tex]a = r\cdot \cos \theta[/tex] (2)
[tex]b = r\cdot \sin \theta[/tex] (3)
Where:
[tex]r[/tex] - Magnitude of the complex number, dimensionless.
[tex]\theta[/tex] - Direction of the complex number, measured in radians.
If we know that [tex]r = 40[/tex] and [tex]\theta = \frac{7\pi}{6}[/tex], then the rectangular form of the number is:
[tex]a = 40\cdot \cos \frac{7\pi}{6}[/tex]
[tex]a = -20\sqrt{3}[/tex]
[tex]b = 40\cdot \sin \frac{7\pi}{6}[/tex]
[tex]b = -20[/tex]
The rectangular form of [tex]z=40\cdot\left(\cos \frac{7\pi}{6}+i\,\sin \frac{7\pi}{6}\right)[/tex] is [tex]z = -20\sqrt{3}-i\,20[/tex]. The correct answer is C.

Answers
Reason:
The x value is horizontal. Thus anything that says left or right is talking about the x value.
The x value is listed first on the point
(x, y)
When the x value goes left it is negative
When it goes right it is positive
The y value is vertical
It is listed last on the point (x , y)
When it goes up it is positive
When it goes down it is negative

A baker decorates 61 cupcakes in 30 minutes. She decorates cupcakes at a constant rate. How many cupcakes can the baker decorate per minute?
Answers
Answer:
2.03 cupcakes per minute.
Step-by-step explanation:
The baker can decorate (61/30) cupcakes per minute, hence she can decorate 2.03 cupcakes per minute.
Hope this helped!
Answer:
The baker can decorate 2 cupcakes per minute
Step-by-step explanation:
The baker can decorate 2 cupcakes per minute and to find this you would divide 61 by 30 and you'd get 2.03333 repeating but you can't decorate three hundredths of a cupcake so you would round it to the nearest whole number to get 2 cupcakes per minute
Graph the line that passes through the points (9,-8) and (9,6) and determine the
equation of the line.
Answers
Answer:
x = 9
Step-by-step explanation:
The standard form of equation of a line is expressed as y = mx+c
m is the slope
c is the y intercept
Note that the line does not have a slope and the x intercept of the line is a point where the line cuts the x axis. Hence the equation of the line will be expressed as x = c where c is the x intercept;
From the graph, the x intercept =9. Hence the equation of the given line is x = 9

For his long distance phone service, Ravi pays a $2 monthly fee plus 12¢ per minute. Last month, Ravi's long distance bill was $12.68. For how many minutes was Ravi billed?
Answers
Answer:
[tex]89\ \text{minutes}[/tex]
Step-by-step explanation:
Let the number of minutes Ravi spoke for be [tex]x[/tex]
The fixed monthly fee is $2
Per minute Ravi is charged 12¢ = $0.12
The charge in a month will be
[tex]y=2+0.12x[/tex]
In one month Ravi was billed $12.68. So [tex]y=12.68[/tex]
[tex]12.68=2+0.12x\\\Rightarrow x=\dfrac{12.68-2}{0.12}\\\Rightarrow x=89\ \text{minutes}[/tex]
So, Ravi spoke for [tex]89\ \text{minutes}[/tex] that month.

Calculating average speed:
1. A person walks 6.0 meters in a time of 2.0 seconds. What is the average speed. PLEASE HELP!!!
Answers
Answer:
3 meters per second.
Step-by-step explanation:
The formula for finding speed is: [tex]s = \frac{d}{t}[/tex]. D is distance. T is time. So in your case, you would divide 6.0 (distance) by 2.0 (time). Your answer is 3. Add meters per second because you divided meters/seconds.
Hope it helps!
Speed= distance divided by time
6.0 divided by 2.0 = 3

Option B: 5(4) - 2(1) = 20 - 2 = 18. Works.
