The value of the directrix is -5/4.
According to the statement
we have given that the equation of parabola is y2 = 5x. And we have to find that the which equation represents the directrix.
We know that the general equation of parabola is
(y - k)2 = 4a(x - h) -(1)
and given parabola equation is
y2 = 5x. -(2)
After comparing the both equations we get k=0 and h=0
And the formula to find the directrix is
x = h - a
Substitute the values of h and a in it then
x = 0-5/4
x = -5/4.
Here the directrix is -5/4.
So, The value of the directrix is -5/4.

Answer:
1.75 meters² or 175 centimeters²
Step-by-step explanation:
Step 1: Find Area of the Base.
- Base is a square with dimensions of 7cm by 7cm
Step 2: Find the Area of the Triangles.
- Each triangle has a base of 7cm and a height of 9cm.
- 7 x 9 = 63, and 63/2 = 31.5
- 31.5 x 4 = 126 cm²
Step 3: Add the areas together.
- 175 cm²
Thus, the surface area is 1.75 m^2 or 175 cm^2.
