As the focus is at (0,5) it will be symmetrical about the y axis and will open upwards
General formula is x^2 = 4ay where a is the y coordinate of the focus
So its y = x^2/5*4
y = 1/20 x^2
They would get 3/32 of the cake if they split it evenly
The set when z = -5 is {-27, -9, -5}
<h3>How to determine the set elements?</h3>
The set is given as:
{(4z-7,z-4,z) |z is any real number}
When z=-5, we have:
4z - 7 = 4(-5) - 7 = -27
z - 4 = -5 - 4 = -9
z = -5
So, we have:
{(4z-7,z-4,z) |z is any real number} ⇒ {-27, -9, -5}
Hence, the set when z = -5 is {-27, -9, -5}
