Answer:
Identity property of Division (OR Identity property of one)
Step-by-step explanation:
The Identity property tells us that any number mutiplied by or divided by one is the same number.
Examples:
4 * 1 = 4
4/1 = 4
Answer:
0N
Step-by-step explanation:
Force = mass * acceleration
Given
Mass = 5kg
velocity = 19m/s
IF the velocity of the body is constant, then the acceleration will be zero.
Force = 5 * 0
Force = 0N
Hence the net force on the rock is 0N
Answer:
sqrt(80)
sqrt(18)
sqrt(12)
Step-by-step explanation:
sqrt(196) = 14 which is rational.
7/18 is a fraction. There is nothing the matter with it. It is rational.
sqrt(80) = sqrt(16 * 5) = sqrt(4*4* 5) = 4 sqrt(5) which is irrational.
sqrt(18) = sqrt(9*2) = sqrt(3*3*2) = 3*sqrt(2) which is irrational.
sqrt(12) = 2sqrt(3) which is irrational
Rule: if there is anything left under the root sign then the starting number is irrational.
