Answer:
Step-by-step explanation:
We have been given an equation . We are asked to find the solutions of our given equation.
First of all, we will cross multiply our given equation as:
Subtract from both sides:
Now we will factor out .
Now we will factor by splitting the middle term.
Now we will use zero product property and solve for x as:
Now, we will check for extraneous solutions.
We can see that will make both denominators zero because our function is not defined at
.
Therefore, the solution for our given equation is .
We will need to find the area of the circle. We will use this formula:
A =
* radius^2
The question says we will use 3.14 for.
And we know radius is equal to 22.
A = 3.14 * 22^2
A = 3.14 * 484
A = 1519.76
Round to the nearest tenth.
A = 1519.8
So, the maximum area the sprinkler can water is <span>1519.8</span> ft squared.
