Step-by-step explanation:
Difference is 94400000-9290000=85110000 miles. This distance in feet is 4.468275*(10)^(11)
Who knows, it is weird and impossible
Answer:
C
Step-by-step explanation:
The focus and directrix are equidistant from any point (x, y) on the parabola.
Using the distance formula
= | y - 4 |
= | y - 4 |
Square both sides
x² + (y + 4)² = (y - 4)² ← expand parenthesis on both sides
x² + y² + 8y + 16 = y² - 8y + 16
Subtract y² - 8y + 16 from both sides
x² + 16y = 0 ( subtract x² from both sides )
16y = - x² ( divide both sides by 16 )
y = - x², or
f(x) = - x² → C
