Answer:
(4cos150, 4sin150) or (4cos5pi/6, 4sin5pi/6)
Step-by-step explanation:
Given the rectangular coordinate
(2√3,-2)
x = 2√3
y = 2
For polar coordinate;
x =r cos theta
y = rsin theta
r = √x²+y²
r = √(2√3)²+(-2)²
r = √4(3) + 4
r = √12+4
r = 4
theta = arctan(y/x)
theta = arctan(-2/2√3)
theta = arctan(-1/√3)
theta = -30
theta = 180 - 30
theta = 150degrees
x = 4cos 150
y = 4sin150
The polar coordinate is (4cos150, 4sin150) or (4cos5pi/6, 4sin5pi/6)
The polar coordinates of the point are
Answer: 40
Step-by-step explanation: The pattern goes by 8's
Answer:
1 : 12 . . . . sketches : minutes
Step-by-step explanation:
We know 1 hour is 60 minutes, so the given numbers can be written as ...
5 sketches : 60 minutes
and reduced by dividing by 5 to get the ratio ...
sketches : minutes = 1 : 12
Original equation: 9(8j + 2 +j)
1st use Distributive property:
Multiply 9 by each term in the parenthesis:
72j + 18 + 9j
2nd use Addition Property to combine like terms:
81j +18
