Step-by-step explanation:
Given
no of houses that can be served by water is directly Proportional to the square of diameter
where k =constant
10 cm diameter can supply 40 houses
-----------1
For d=30 cm Pipe
-------------2
divide 1 & 2
(b)for N=1440 houses
----------------3

I believe it should be at (-5,2)
Let me double check tho one sec
Answer:
Here we have the equation:
y = 4*x^2 - 4*x - 1
And we should have the graph (you can see it below this answer)
Now we want to find the solutions of:
4*x^2 - 4*x - 1 = 0
These solutions will be the two values of x at which the graph of our function intersects the line y = 0, that is the x-axis.
Then we need to find the two values of x at which our graph intersects the x-axis.
In the graph, we can estimate the solutions as:
x = -0.2
x = 1.2
To find the exact solutions we can use the Bhaskara's equation, and we will find that the solutions are given by:
Then the two solutions are:
x = (4 + 5.66)/8 = 11.2075
x = (4 - 5.66)/8 = -0.2075
