Answer:
x=60.56, x=-82.56
Step-by-step explanation:
Solve using quadratic formula
Formula is
0.05x^2 + 1.1x = 250
Subtract 250 on both sides
0.05x^2 + 1.1x - 250=0
a= 0.05, b=1.1 , c=-250
Plug in the values in the formula
Now make two equations , one with + and one with -
then we solve for x
x=60.56
x=-82.56
Answer:
The sprinkler can spread water 18 feet away.
Step-by-step explanation:
We are given the following in the question:
Area formed by watering pattern = 1,017.36 square feet
We have to find the how far the sprinkler spread the water.
The sprinkler covers a circular area. We need to find the radius of this circular area to find the how far the sprinkler spread the water.
Area of circle =
where r is the radius of the circle.
Putting values, we get,
Thus, the sprinkler can spread water 18 feet away.
