Answer:
2, 120 degrees
Step-by-step explanation:
The first step in finding the polar form is finding the modulus, r
r= sqrt( x^2 + y^2)
r = sqrt( (-1)^2 + sqrt(3)^2)
r = sqrt(1+3)
r= sqrt(4)
r =2
The next step is finding the angle
theta = arctan (y/x)
theta = arctan (sqrt(3)/-1))
theta = arctan (-sqrt(3))
theta = -60
The point (-1, sqrt(3)) is in the 2nd quadrant, but our angle is in the 4th quadrant, so we add 180 degrees
theta = -60 + 180 = 120
theta = 120 degrees
Answer:
= 10x+35
Step-by-step explanation:
(5)(2x+7)
(5)(2x)+(5)(7)
=10x+35
Answer:
Relative frequency method
Step-by-step explanation:
Relative Frequency is a classical approach to probability. It is the ratio of the occurrence of a singular event to the total number of outcomes. This is a tool that is often used after data collection.
In relative frequency, a single part of the data can be compared to the total amount of data collected. This is cleearly observed in the given question.
