Answer:
Step-by-step explanation:
Given:
Focus of parabola: (-4, 6)
Directrix: y = 2
Required:
Equation for the parabola
<h2>
<u>SOLUTION:</u></h2>
Using the formula, 
, the equation for the parabola can be derived.
Where,
a = -4
b = 6
k = 2
Plug these values into the equation formula
Answer:
62.8319 mi²
Step-by-step explanation:
The volume formula here is V = (area of base)(height),
If we fill in the given measurements, we get:
V = π(2 mi)²(5 mi) = 62.8319 mi²
Y - 5 = m[ x - ( - 2 ) ] is <span>the "point-slope" form of your staright - line equations;
y - 5 = m( x + 2 ) ;
But, your line is parallel to y = ( 2 / 3 )x + 1;
m = 2 / 3;
Finally, y - 5 = ( 2 / 3)( x + 2);
y = 5 + ( 2 / 3)x + 4 / 3;
y = ( 2 / 3 )x + 15 / 3 + 4 / 3 ;
y = ( 2 / 3 )x + 19 / 3.

Answer:
k=10
Step-by-step explanation:
4k + 12= 52
minus 12 on both sides
4k=40
now divide by 4
k=10
178 - (-395)
178 + 395 = 573
the distance between -395 and 178 is 573
hope this helps
