Answer by JKismyhusbandbae: (Answer is in picture)
Cos(x)=0.5
x=pi/3
since cos is postive in the fourth quadrant and first quadrant
x=pi/3+2*pi*k where k is an integer
fourth quadrant
x=(-pi/3)+2*pi*k where k is an integer
the first 3 values of K in the first quadrant are
pi/3,7*pi/3,13*pi/3
the first three postive values for the fourth quadrant are
5*pi/3,11*pi/3,19*pi/3
so the smallest three are
pi/3,5*pi/3,7*pi/3,11*pi/3
Answer:
yes it is and its also a coordinate
Step-by-step explanation:
a rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers. The denominator in a rational number cannot be zero. ... In other words, most numbers are rational numbers.
Using the equation of best fit provided:
y=0.216x + 32.575
The slope is the number with the x, so the slope is 0.216 and the y- intercept is the number added at the end. The y intercept is 32.575
