Answer:
An individual angle is equal to 90°and is also called a right angle
Answer:

Step-by-step explanation:
we are given a quadratic equation
we know that quadratic equation is same as equation of parabola
so, we can use formula

Focus is

now, we can compare it with given focus
=(8,-8)
we get


Directrix is

we are given directrix =-6

we got two equations as


now, we can add both equations
and we get




now, we can find 'a'


now, we can plug back all values
and we get
So, equation of parabola is

By taking c(x)=28,900+100x+0.01x2, we arrive at x=1445000/50c-5001; c≠5001/50
We can determine that 1,445,000 can be produced and it will cost $50.00
