$200/5 lamps= $40 per lamp
Final answer: $40
If the equation is
then rewrite the equation as
Divide boths sides by 7:
Since , we can factorize this as
Now solve for <em>x </em>:
where <em>n</em> is any integer.
If you meant sin(2<em>x</em>) instead, I'm not sure there's a simple way to get a solution...
Answer:
y = (x + 8)² + 6
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
add/subtract (half the coefficient of the x- term )² to x² + 16x
y = x² + 2(8)x + 64 - 64 + 70
= (x + 8)² + 6 ← in vertex form
