Answer:
a. y^2 = 8x.
Step-by-step explanation:
The general equation for this type of parabola is y^2 = 4ax where a is the distance between the vertex and the focus. The focal width = 4a.
So the answer to this is y^2 = 8x.
Answer:
x = 10
Step-by-step explanation:
The 2 chords are equal in length so
7x + 5 = 9x - 15
2x = 20
x = 10
Using proportions, it is found that the minimum payment the hospital will accept from the patient is of $50.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
15% of the balance of $350.00 is given by:
B = 0.15 x 350 = $52.5.
Which is a higher amount than $50, hence the minimum payment the hospital will accept from the patient is of $50.
