Answer:
1. y = 9(x+1/2)^2 -13/4
Step-by-step explanation:
y = 9x^2 + 9x – 1
first isolate the x terms
y = 9(x^2 +x) -1
then add 1/4 inside the brackets to make it a perfect square trinomial (half of the coefficient of the x term squared is how we get 1/4)
since we just added 1/4 we need to subtract what we just added to balance the equation. so 1/4 times 9 is 9/4 ( the number we just added to the equation). then you subtract 9/4 outside of the brackets.
y = 9(x^2 +x +1/4) -1 -9/4
then simplify
y = 9(x+1/2)^2 -13/4
To find the cost of labor for one worker, you multiply the wage by the number of hours worked.
40 * 8 = 320
Because there are two workers, now you double it.
320 * 2 = 640
To find the percentage of the revenue that this is, you do the labor cost divided by the revenue.
640 / 2000 = 0.32
Move the decimal two places to the right to get the percentage.
0.32 = 32%
The labor cost is 32% of the revenue.
