You have to plug in 0 to each variable and solve to get each axis intercepts giving you. (0,-3) (6/5,0)
Answer:
The incorrect statement is <em>A. Alpha and beta particles pose little or no hazard to human health.</em>
Step-by-step explanation:
Alpha particle - the nucleus of a helium atom, made up of two neutrons and two protons with a charge of +2. Certain radioactive nuclei emit alpha particles. Alpha particles generally carry more energy than gamma or beta particles, and deposit that energy very quickly while passing through tissue. Alpha particles can be stopped by a thin layer of light material, such as a sheet of paper, and cannot penetrate the outer, dead layer of skin. Therefore, they do not damage living tissue when outside the body. When alpha-emitting atoms are inhaled or swallowed, however, they are especially damaging because they transfer relatively large amounts of ionising energy to living cell.
Beta particles - electrons ejected from the nucleus of a decaying atom. Although they can be stopped by a thin sheet of aluminium, beta particles can penetrate the dead skin layer, potentially causing burns. They can pose a serious direct or external radiation threat and can be lethal depending on the amount received. They also pose a serious internal radiation threat if beta-emitting atoms are ingested or inhaled.
Therefore, <em>alpha and beta particles do pose affect the health of human beings.</em>
Answer:
8 pieces of candy
Step-by-step explanation:
Take the original amount of candy in the bowl to be 
.
It says that 20 pieces of candy were added, therefore there are 
pieces of candy in the bowl.
Half of the candy is gone, therefore 
pieces of candy are left in the bowl.
After half of the candy is gone, there are 14 pieces left, so we can say that
