Answer:
-4y = x², or y = - x²/4, or y = -(1/4)x²
Step-by-step explanation:
Because the focus is beneath the directrix, this vertical parabola opens down. The general formula is 4py = x².
Because the distance between focus and directrix is 2 units, p = -1 here. The negative sign shows that the parabola opens down.
4py = x² becomes 4(-1)y = x², or -4y = x², or y = - x²/4
The answer is he will make $300 commission for 25 TV sets sold. The first thing you need to do is find out how much commission he makes on each TV. So we take $120 and divide by 10% and that gives us $12. So $12 is the amount of commission per TV. Then we just need to multiply the $12 by 25 TV sets. That gives us the answer of $300 commission total.
A second way to solve this problem is by taking the $120 and multiplying that by the 25 TV sets. That gives you $3,000 total for the 25 TV sets. Then you just divide the 10% commission Mike will make. That also gives you the answer of $300 commission.
