(12/30)x100 is 40%
This is percent of incorrect answers. The total percent must be 100% so subtract 100-40=60%.
60% answers were answered correctly.
Answer:
tita = 0 , 180, 270, 360. ( tita = 0 ≤ x ≤ 360).
Step-by-step explanation:
sin tita + sin ^2 tita = 0
sin tita( sin tita + 1) = 0
sin tita = 0, - 1.
For angles between 0 and 360 inclusive sin = 0 gives 0, 180 and 360 degrees. The angle whose sine is -1 is 270 degrees.
tita = 0 , 180, 270, 360.
Answer:
Step-by-step explanation:
To find out what's the weight missing we must subtract the expected weight from the actual weight.
The expected weight is 140kg, the actual weight is 132kg and 9 hectograms, remember that 1 hectogram 0.1kg, then 9 hectogram is 0.9. Then the actual weight is 132.9kg.
The weight of the missing equipment will be
The weight of the missing equipment is 7.1 kg
Answer:
m^2+m+1
Step-by-step explanation:
- m^3 - 1= (m-1)(m^2+m+1)
- m^4 + m^2 + 1= m^4+2m^2+1 - m^2= (m^2+1)^2 -m^2= (m^2+m+1)(m^2-m+1)
- m^2+ m + 1
HCF= m^2+m+1 which is the factor of all three polynomials
