Answer:
18(cos(4pi/3) + i sin(4pi/3))
Step-by-step explanation:
step 1: find the modulus (|z|=√(a^2 + b^2)
|z|=√((-9)^2+(-9√3)^2)= 81+243= 324 => √324=18
step 2: find the argument using theta =tan^-1 (y/x)
theta=tan^-1((-9√3)/-9) = √3
the tangent value of √3 in the third quadrant has the degree measure of 240 and the radian measure of 4pi/3.
Now put them together!

Answer: D is the correct answer.
Step-by-step explanation: The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the third side and answer D does exactly that because 2.6 + 8.1 =10.7 which is greater than the third side which would be 10.2.

Please help 16 points due tomorrow
Answer:
1) 26.1% increase
2) 20% decrease
Work:
1)
-subtract the larger # from the smaller # to figure out what the change was.
[tex]8.8 - 6.5 = 2.3[/tex]
-divide 2.3 by the orriginal ammount (8.8) to find your answer as a decimal
[tex]2.3 \div 8.8 = 0.261[/tex]
-take 0.261 and multiply it by 100 to have your answer as a percent
[tex]0.2614 \times 100 = 26.1[/tex]
-if the original number increased than it is percent increase and if the original number decreased than it is percent decrease
2)
-subtract the larger # from the smaller # to figure out what the change was.
[tex]15 - 12 = 3[/tex]
-divide 2.3 by the orriginal ammount (15) to find your answer as a decimal
[tex]3 \div 15 = 0.2[/tex]
-take 0.2 and multiply it by 100 to have your answer as a percent
[tex]0.2 \times 100 = 20[/tex]
-if the original number increased than it is percent increase and if the original number decreased than it is percent decrease

A pulley rotates through 107° in one minute. How many rotations does the pulley make in an hour!
The pulley makes rotations per hour.
(Simplify your answer. Round to the nearest whole number.)
Answer:
18 rotations.
Step-by-step explanation:
As there are 360 degrees in a circle, by proportion, the time for 1 rotation
= (360/107) * 1
= 3.364 minutes.
So the number of rotations in 1 hour (60 minutes)
= 60 / 3.364
= 17.83
Number of rotations does the pulley make in an hour is 18.
Here,
A pulley rotates through 107° in one minute.
What is rotations?
The action or process of rotating on or as if on an axis or center.
Now,
As there are 360° in a circle, by proportion;
Time for one rotation = (360/107) x 1
= 3.364 minutes
Hence, number of rotations in 1 hour
= 60 / 3.364
= 17.83
So, Number of rotations does the pulley make in an hour is 18.

May I plz get some help plz
Step-by-step explanation:
5x +10° + 58° = 11x + 2°( Exterior angle of a triangle is equal to the sum of two opposite interior angles)
5x + 68° = 11x + 2°
11x - 5x = 68° - 2°
6x = 66°
x = 66° / 6
Therefore x = 11°
