Answer:
=0
Step-by-step explanation:
4(11+7)-9•8=
(44+28)-72=
72-72=0
Polar form of a complex number is r( cos(theta) + i sin(theta) )
r is equal to the total distance created by the rectangular coordinates of the complex number
r = Root(4^2 + (-4)^2) = Root(32) = 4 Root(2)
To find theta, if a > 0, use arctan(b/a), where:
a = the first number
b = the second number
arctan (-4/4) = -45 degrees (-0.7854 radians)
Your answer is 4 Root(2) (cos(-45) + i sin(-45))
Answer:C
Step-by-step explanation:In a box plot the median is the line that lines with the number that on the box plot. So the line is between 8 and 9 but to find the number that is between 8 and 9,first add 9+8=17 then divide 17 with 2 which is 17÷2=8.5.Therfore the numbers that are between 8 and 9 is 8.5.
