Answer:
I need the graph
Step-by-step explanation:
According to the vertex and the directrix of the given parabola, the equation is:
![y = \frac{3}{4}(x - 1)^2 + 4](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B3%7D%7B4%7D%28x%20-%201%29%5E2%20%2B%204)
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:
![y = a(x - h)^2 + k](https://tex.z-dn.net/?f=y%20%3D%20a%28x%20-%20h%29%5E2%20%2B%20k)
In which a is the leading coefficient.
The directrix is at y = k + 4a.
In this problem, the vertex is (1,4), hence:
![h = 1, k = 4](https://tex.z-dn.net/?f=h%20%3D%201%2C%20k%20%3D%204)
The directrix is at y = 7, hence:
![4 + 4a = 7](https://tex.z-dn.net/?f=4%20%2B%204a%20%3D%207)
![a = \frac{3}{4}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B3%7D%7B4%7D)
Hence, the equation is:
![y = a(x - h)^2 + k](https://tex.z-dn.net/?f=y%20%3D%20a%28x%20-%20h%29%5E2%20%2B%20k)
![y = \frac{3}{4}(x - 1)^2 + 4](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B3%7D%7B4%7D%28x%20-%201%29%5E2%20%2B%204)

Answer:
x = y + z
=> z = y - x

Hope u understand
Answer:
B and D
Step-by-step explanation:
A difference of squares has the form a² - b²
4p² - 9 = (2p)² - 3² ← is a difference of squares
q² - 36 = q² - 6² ← is a difference of squares
To start with, convert 52 feet into metres
1 Feet= 0.3048
52 feet= ?
The number of meters= 52*0.3048
The number of meters= 15.8496 metres
The school need to add a further 1.8496 metres
