8.4341
Step-by-step explanation:
ANSWER

EXPLANATION
Since the parabola has the (0, 0) and the directrix at y=2.
The equation is of the form

where (h,k) is the vertex.
The vertex is half way between the directrix and the focus.
The vertex will be at (0,1)
and is the distance from the vertex to the focus which is 1.


Answer:
a = 6
Step-by-step explanation:
(3.14 * 18) * 17.5 = 3.14 * (3a * 17.5)
3.14(3x * 17.5) = (3.14 * 18) * 17.5
3.14(3a * 17.5) = 3.14 * 18 * 17.5
3.14(3a * 17.5) = 989.1
3.14 * 3a * 17.5 * 100 = 989.1 * 100
16485a = 98910
a = 98910/16485
a = 6
Answer:
y - 5 = 1/4 (x - (-1))
Step-by-step explanation:
Since we have a parallelogram, then WX and YZ must be parallel
mathematically, the general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
if two lines are parallel, the value of their slopes is same
for the first line, we have;
y = 1/4x - 6
The slope of the first line is 1/4
this is the slope of the second line too
By using;
y-y1 = m(x-x1)
where (x1,y1) is the point on the line
we have;
y - 5 = 1/4 (x - (-1))
