ANSWER
Vertex form:
Vertex
V(-4,-11)
EXPLANATION
The given expression is
We complete the square to get the vertex form.
Add and subtract half the square of the coefficient of x.
The vertex is
V(-4,-11)
The only way to make a decimal out of either of those numbers is to write a decimal point with some zeros after it.
500,000 = 500,000.000
60,000,000 = 60,000,000.00000
etc.
the assumption being that "x" is a plain variable whilst "y" is a function, that matters because the chain rule would be needed for a function, not so for a plain variable.
now, we know that y(5) = -23, which is another way of saying that when x = 5, y = -23, but we already knew that, we can get that by simply plugging it into the equation hmmm y'(5), well
The solution is <span>B. π/12+nπ
</span>proof
sinx cosx = 1/4 is equivalent to 2 <span>sinx cosx = 1/2 or sin2x =1/2
so 2x = arcsin(1/2) = </span>π/6 + 2nπ, so x = π/12+nπ
Answer:
x = 6
Step-by-step explanation:
All triangle angles add up to 180 so:
90 + 5x + 6 + 54 = 180
5x + 150 = 180
5x = 30
x = 6
