Step-by-step explanation:
Line l is bisector of MO... (given)
![\therefore NO + NO = MO..[From \:(1)]](https://tex.z-dn.net/?f=%20%5Ctherefore%20NO%20%2B%20NO%20%3D%20MO..%5BFrom%20%5C%3A%281%29%5D%20)
Thus Proved
F+g(x) = f(x) + g(x) = 3x-1 + x+2 = 4x+1
<span>As the age of the U-235 sample is 2.631 billion years, and the half-life of U-235 is 713 million years, the sample has undergone 2.361 X 1,000,000,000 / 713 X 1,000,000 = 3.69 half lives. In each half-life the sample reduces to half its original weight according to the radioactive Half-Life Formula:
ln (Nt /N0) = -kt, where N0 = mass of the original weight of radioactive material, Nt = mass of radioactive material at time t, k = decay constant and t = time interval . We have to put Nt/N0 = 1/2 for time interval = half-life.</span>
1/5 of a foot
Simply subtract the height of Pancho’s sandcastle (3/5 of a foot) minus the height of his sister’s sandcastle (2/5 of a foot) to find a difference of 1/5 of a foot, meaning Pancho’s sandcastle was 1/5 of a foot taller than his sister’s sandcastle.
