Given the directrix of y = -1 and focus of (0, 3), which is the equation of the parabola?

guajiro [1.7K]

Answer:

$y=\dfrac{1}{8}x^2+1$

Step-by-step explanation:

Since the vertex is right between the vertex and the directrix, the y value of the vertex must be (3+(-1))/2=1. The x coordinate will just be the same as that of the focus, or in this case 0. This means that the vertex will be at (0,1). Since the graph opens toward the focus, it will be opening up, and since its vertex is at (0,1), it will have an equation of:

$y=\dfrac{1}{8}x^2+1$

Hope this helps!

An art class is planning to paint a rectangular mural with an area of 60 square feet. It has to be at least 4 feet high but no m

Strike441 [17]

Hello!

There are three possible lengths.

We need to keep in mind that the total area cant exceed $60 ft^{2}$ , so, knowing that, we just need to find numbers that can be multiplied giving as result 60.

First combination:

$4ft(height)X15ft(width)=60 ft^{2}$

Second combination:

$5ft(height)X12ft(width)=60 ft^{2}$

Third combination:

$6ft(height)X10ft(width)=60 ft^{2}$

Have a nice day!
