Answer: Yea at least brainly deleting them when they catch them
Step-by-step explanation:
Given:
The focus of the parabola is at (6,-4).
Directrix at y=-7.
To find:
The equation of the parabola.
Solution:
The general equation of a parabola is:
...(i)
Where, (h,k) is vertex, (h,k+p) is the focus and y=k-p is the directrix.
The focus of the parabola is at (6,-4).

On comparing both sides, we get

...(ii)
Directrix at y=-7. So,
...(iii)
Adding (ii) and (iii), we get



Putting
in (ii), we get



Putting
in (i), we get


Therefore, the equation of the parabola is
.
Given Information
The radius is 3.
Circumference
To find the circumference, use 2πr.
2*3.14*3=18.84
The circumference is 18.84 cm^2.
Area
To find the area, use πr^2.
3.14*3^2=28.26
The area is 28.26 cm^2.
Ok well check it out work out how long it took to hose 1/7 the of the lawn which is 2/5 hours. Times that by 7 to get the whole lawn: 7 x 2/5 = 2.8 hours hope that helps
Answer: The maximum revenue is $1,000,000.
The function that is given is a quadratic equation and the graph would be an upside down parabola.
Therefore, the maximum revenue would be at the vertex of the parabola.
To find the vertex, we can use the expression -b/2a to find the x-value.
It would be -4000/2(-4) = 500
Now, input 500 for p and you will get a revenue of 1,000,000.
