pentagon [3]

A parabola with focus of (3, 4) and a directrix of y = 0 has the equation of the parabola as

  • y = 1/8(x - 3)²  + 2

<h3>How to write the equation of parabola </h3>

Quadratic equation is equal to  parabolic equation, when the directrix is at y direction is of the form:

(x - h)² =  4P (y - k)

OR

standard vertex form, y = a(x - h)² + k    

where a = 1/4p

The focus

F (h, k + p) = (3, 4)

h = 3

k + p = 4

P in this problem, is the midpoint between the focus and the directrix

P = (4 - 0) / 2 =  2

p = 2

the vertex

v(h, k)

h = 3

k + p = 4, k = 2

v(h, k) = v(3, 2)

substitution of the values into the equation gives

(x - h)² =  4P (y - k)

(x - 3)² =  4 * 2 (y - 2)

(x - 3)² =  8 (y - 2)

y = 1/8(x - 3)²  + 2

The quadratic equation is of the form y = 1/8(x - 3)²  + 2

valina [46]

Answer:

Step-by-step explanation:

As we know that in an hour there are 3600 seconds so

1.8 x 3600 = 6480

 6480 / 1609 = 4.02 miles / hr

  4.02 - 2.5 = 1.5( by substracting the speed)

so correct option is D which is

 Talia swims about 1.5 miles per hour faster than Alina

The area of the following rectangle is 30 square units. What is the value of x?
Pepsi [2]
Hello!

To find the area of a rectangle you do length * width

You can plug in the values you know

(x - 2) * 5 = 30

Divide both sides by 5

x - 2 = 6

Add 2 to both sides

x = 8

The answer is 8

Hope this helps!
