The equation of the parabola whose focus is at (0, 5) and directrix at y = -5 is:~ y = (1/20)x²
~ y = -(1/20)x²
~ x = (1/20)y²

Answers

The equation of parabola will be y=(1/20)x² .

Given,

Focus : (0, 5)

Directrix : y = -5

Now,

The standard equation of parabola is : x² = 4ay or y² = 4ax .

Focus is above directrix, it opens up

x²=4ay

a is distance from directrix to vertex

Since it opens up, a is positive

from -5 to 0 is 5 units

x²=4(5)y

x²=20y

solve for y

divide both sides by 20

y=(1/20)x²

for a parabola at vertex (0,0)
we see that we have to go up and down
therfor it opens up or down

since focus is above directix, it opens up
x^2=4Py
p is distance from directix to vertex
since it opens up, P is positive
from -5 to 0 is 5 units
x^2=4(5)y
x^2=20y
solve for y
divide both sides by 20
y=(1/20)x^2

A yard is equal in length to three feet. The function f(x) takes a measurement in yards (as input) and returns a measurement in feet (as output).

Answers

Answer:  Choice A

36.6

====================================

Work Shown:

f(x) = 3x

f(12.2) = 3*12.2

f(12.2) = 36.6

x is the length in yards, and f(x) is the length in feet.

12.2 yards = 36.6 feet

To convert from yards to feet, we multiply by 3. That explains how

  • 1 yard = 3 feet
  • 2 yards = 6 feet

as shown in the screenshot.
