to translate a graph up you need to add the amount you want to move it to the end of the equation, not to the variable.
The answer would be y = sin x + π
For the given vectors 
and 
The dot product of vectors a and b is defined as = 
So, 
= -16+12
= -4
Answer:
Wait wait wait this makes no sense?
Step-by-step explanation:
Multiply each term by a^2b^2:-
b^2y^2 + a^2x^2 = a^2b^2
subtract a^2x^2 from both sides
b^2y^2 = a^2b^2 - a^2x^2
Now divide both sides by b^2
y^2 = a^2 - a^2x^2 / b^2 = a^2 (1 - x^2/b^2)
take positive square root ( because y > 0)
y = a sqrt(1 - x^2/b^2)
