Answer:
40 units
Step-by-step explanation:
i took the test
Answer: The factors of 60. 1,2,3,4,5,6,10,12,15,20,30,60, Related Links : Is 60 a rational number?
7.
I: when no unit, assume radians
II: hmm, 0 to pi/2 radians is 1st quadrant, pi/2 to pi is 2nd, pi to 3pi/2 is 3rd and 3pi/2 to 2pi is 4th
pi/2<1.57<pi so it is in 2st quadrant
III:
cos is negative here because cos is the x axis
IV. no because the value of cos(1.75rad) should be negative
8.
I: from 0 to 90 is 1st
from 90 to 180 is 2nd
from 180 to 270 is 3rd
from 270 to 360 is 4th
so it is in 2nd quadrant
II: sin is positive here because sin is the y axis
III: sin should be positive here so a negative value is not reasonable
IV: maybe she put 125 without putting the degrees and the calculator thought that it was radians
