Yes because 16 is greater than 15 and it has to be greater or equal to 15
The conversion factor between radians and revolution as measures of angle is 2π rad is equal to 1 revolution. Converting the given angular velocity to rev/s,
(2.8 rad) x (1 rev / 6.28 rad) = 70/157 revolution per second
Dividing the given angle, 20 rev by the velocity,
(20 rev) / (70/157 rev/s) = 44 6/7 s
Thus, the answer is approximately 44.9 seconds.
D
A nonproportional relationship is a linear line that doesn’t go through the origin.
y=3x+0 does go through the origin because the y-intercept (the b) is 0
Y=x/4 also has a y-intercept of 0
Y=7x also has a y-intercept of 0.
y=2/5x+7 does not go through the origin because the line passes the y-axis at (0,7) which is the y-intercept.
