If he made 25 percent profit, the selling price (1200 naira) is 125 percent.
If 125% is equal to 1200 naira
100 percent (the original) will be 100 × 1200 divided by 125
Which is 120000 ÷ 125
Therefore, the cost price is 960 naira
Answer:
The equation
represents the equation of the parabola with focus (-3, 3) and directrix y = 7.
Step-by-step explanation:
To find the equation of the parabola with focus (-3, 3) and directrix y = 7. We start by assuming a general point on the parabola (x, y).
Using the distance formula
, we find that the distance between (x, y) is

and the distance between (x, y) and the directrix y = 7 is
.
On the parabola, these distances are equal so, we solve for y:

Properties can help you divide because if you didn't follow them we would have incorrect answers and would be very held back in science and mathematics
Basically you multiply the original length by the scale factor. So let's say there's a side length of 10 and the scale factor is .5, then you multiply 10 by .5 and get 5, that's all scale factor is . It can get larger/smaller, just depends on the number.
