Answer:
<h3>1kg</h3>
Step-by-step explanation:
According to Newton's second law
Force = mass * acceleration
Given
Force = 2N
acceleration = 2m/s^2
Mass =Force/Acceleration
Mass = 2/2
Mass =1kg
Hence the mass of the ball is 1kg
Answer:
Height
Step-by-step explanation:
A=2πrh+2πr2
Step-by-step explanation:
step 1 .simply N/6 equation at the end of step 1 is (7+n/6)-1=0
step 2. rewrite the whole as an equivalent fraction 7=7/1=7.6/6
Answer:
Im pretty sure it's the 2nd one
Answer:
{-infinity, infinity}
no solution
Step-by-step explanation:
|x| +15≥4
Subtract 15 from each side
|x| +15-15≥4-15
|x| ≥-11
This is always true so x can be and real number
{-infinity, infinity}
-2|5x+3| = 8
Divide by -2
-2/-2|5x+3| = 8/-2
|5x+3| = -4
This can never happen because absolute values are zero or greater
no solution
