Remember that for a function of the form

, a parabola, the focus will be:

.
We know that the vertex of the parabola is (0,0), and the sun is the focus of the parabola; we also know that the focus is in the positive y-axis and when the comet is as its vertex, the distance between them is 60'000.000 km; therefore the focus of our parabola is (0, 60'000.000).
Now that we know the focus, we can find

using the focus of the parabola:




Now, the only thing left is replacing the value of

in our equation

:

We can conclude that the equation that represents the path of the comet is
Answer:
y=-15, y=-2, x=10,x=-5
Step-by-step explanation:
Answer:
4 11/16 m²
Step-by-step explanation:
The formula for the area of a rectangle = Length × Width
From the question:
Length = 1 1/4 m
Width = 3 3/4m
Area of the rectangle =
1 1/4 m × 3 3/4 m
= 5/4 m × 15/4 m
= 75/16 m²
= 4 11/16 m²
Area of the rectangle = 4 11/16 m²
Eight and 2 have different place values in the numbers
