Hello, the answer for your question is<span> 12.7.</span>
Separate into two groups
y^3(5y+4) + 5(5y+4)
(y^3 + 5)(5y + 4)
(2,-4) is new reflected coordinates
Well there has to be a right angle in there somewhere as the pole must be perpendicular to the ground.
Using the sine rule:
sinA/a = sinB/b where a = 10, A = 90, b = 5√3, B = B
Re-arrange for B, B = arcsin (b(sinA)/a)
B = arcsin(5√3(sin90)/10)
B = 60 degrees.
Answer is C
Answer:
When two atoms have shared electrons, it is not distinguishable from what atom they are because they are shared in the same orbit, it is called a covalent bond.
Step-by-step explanation:
Atoms in a covalent bond share one or more electrons in the last of their orbitals, the number of electrons in the last orbital will depend on the element in question.
