Answer:
0,3,4,-11
Step-by-step explanation:
Considering the parabolic equation, the equation for the directrix is given by x = 4.9375.
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a horizontal quadratic function, of vertex (h,k), is given by:
(y - k)^2 = 4p(x - h)
The directrix is given by:
x = h - p.
In this problem, the equation is given by:
(y - 2)² = 0.25(x - 5).
Hence h = 5, p = 0.25/4 = 0.0625, hence the directrix is:
x = h - p = 5 - 0.0625 = 4.9375.

Answer:
A. The ability to do something well without wasted time or effort.
<span>In this case, use variables to represent the numbers, Fortunately, they are all in terms of the smaller number. So. let....
x = small number
(x+3) = middle number
2x = large number
If the sum is 75, then all of the numbers added together must equal this. So......
x + (x+3) + 2x = 75
4x + 3 = 75
4x = 72
x = 18
After we find x, we can conclude that..
Smaller number = 18
Middle number = 21
Large number = 36</span>
