First you have to figure out the area of the pool and the path together:
(20m + 2m)*(16m + 2m) = 22m * 18m = 396m^2
When you now subtract the area of the pool from the whole area, you'll get the area of the path:
396m^2 - (20m * 16m) = 396m^2 - 320m^2 = 76m^2 => area of the path
Next step is to figure out the area of one tile:
0,1m * 0,08m = 0,08m^2
Last step is to figure out, how many tiles fit in 76m^2:
76m^2 / 0,08m^2 = 950
costs: 950 * Rs 5 = Rs 4750
F(5)-f (1)/5-1 gives avg over the interval
We want to find an equation for the given solutions and the multiplicity of each solution.
The equation is:

First, assume that we have a given equation and we know that we have solutions {x₁, x₂, ..., xₙ}, each one with multiplicity {m₁, ..., mₙ}.
The equation, of a polynomial that meets these requirements, is given by:

Where A is the leading coefficient and can be any real number.
Now that we know that, here we have the solutions:
- x = 2 with multiplicity 2
- x = -1 with multiplicity 2
We don't have information about the leading coefficient, so we assume it is equal to 1.
Then the equation is:

Answer:
Step-by-step explanation:
How does y change as x increases over a range?
As x increases from -6 to -4, y decreases from 0 to -7
It is a decreasing function in this range and for ranges less than x = -6 as well as the slope is nearly constant
As x increases from -4 to 0, y increases from -7 to 4
It is an increasing function in this range.
For x increasing from zero, y becomes less and less
It is a decreasing function in the range larger than x = 0
