Answer:
Option B. MN/MO
Step-by-step explanation:
In a right angle triangle cosine of any acute angle = Base/ Hypotenuse
In the ∠ NMO Hypotenuse is MO and base of the triangle is MN.
Therefore cos (M) = Base / Hypotenuse = MN / MO
Therefore option B is the right answer.
Answer:8
Step-by-step explan:
(a.b)^2 equals a^2 + 2ab + b^2
The answer to the question is B (the second option 4:2)
The equation is separable, so solving it is trivial:

Integrating both sides gives

Given
and
, we find


so the answer is E.
