Answer:42
Step-by-step explanation:
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
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.

If you can read 20 pages in 45 minutes, how many pages can you read in 18 minutes
Answer:
[tex]8[/tex] pages
Step-by-step explanation:
First, we can find the reading speed per minute before finding how many pages can be read in 18 minutes.
[tex]s=20pages/45minute[/tex] ([tex]s[/tex] refers to reading speed)
[tex]s = \frac{4}{9}pages/minute[/tex] (divide both sides by [tex]45[/tex])
Pages read in 18 minutes [tex]= \frac{4}{9}\times18[/tex]
[tex]=8[/tex] pages

DAILY MATH QUESTIN!
CAN YOU SOLVE IT?
Answer:
2
Step-by-step explanation:
you solve the parentases first which equals 12 and then you take 2 times 12 which is 24 and 48 divided by 24 is 2
Answer:
288
Step-by-step explanation:
Start with what's in parentheses: 9 + 3 = 12Plug 12 in: 48 ÷ 2(12)48 ÷ 2 = 24Plug 24 in: 24(12)24(12) = 24 × 12 = 288I hope this helps!
yuh help please haha
Answer:
B
Step-by-step explanation:
Plug the coordinates in the answer choices to see if they give you 18.
Option A: 5(5) - 2(3) = 25- 6 = 9. Not it
Option B: 5(4) - 2(1) = 20 - 2 = 18. Works.
It has to be B because we've already tested (5,3) in option A and it wasn't correct.
Is the point (3, 4) a solution to the equation 3y = 2x +6 ? Explain why using evidence from your work
Answer:
Yes
Step-by-step explanation:
When graphing it you can see that (3, 4) is clearly a solution. The proper equation using slope intercept form is y= 2/3x + 2.
which function is the inverse of function f?
Answer:
A
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
That's the correct answer because for example if you plug in 1 for x + 2/7, you will get 3/7. But if you plug in 3/7 for 7x -2, you will get 1.
The x equals y.
Hope it helped! The answer is expert verified.

Micah is 6 years younger than Raul.
Write an expression to show how to find Micah's age when Raul is 14.
Answer:
Micah age = x - 6
Micah age is 8 when Raul is 14
Step-by-step explanation:
Let
Raul age = x
Micah is 6 years younger than Raul.
Micah age = x - 6
Find Micah age when Raul is 14.
Micah age = Raul age(x) - 6
= 14 - 6
= 8
Micah age = 8 years
Micah age is 8 when Raul is 14.

What is 2 to the 3rd Power
Answer:
8 is the answer.
Step-by-step explanation:
Let's break down what is being asked.
2 to the third power means 2 times 2 times 2, or simply 2 times itself 3 times.
To solve, do 2 * 2 * 2.
4 * 2 = 8
2 to the third ([tex]2^{3}[/tex]) is equal to 8.

Determine the approximate value of x using basic trigonometry.
(Round to the nearest hundredth..)
Answer:
The value of x = 35.62
Therefore, option C) is true.
Step-by-step explanation:
Given
Ф = 58°
hypotenuse = 42
To determine:
x = ?
We know that the trigonometric ratio
sin Ф = opposite / hypotenuse
Here:
The opposite of Ф = xФ = 58°hypotenuse = 42so substituting the value
sin Ф = opposite / hypotenuse
sin 58° = x / 42
x = 42 × sin 58°
= 35.62
Thus, the value of x = 35.62
Therefore, option C) is true.
