Answer:

C. -7x

Step-by-step explanation:

Only one of the offered choices passes the horizontal line test: at most one point of intersection with any horizontal line.

A: a parabola opening upward, so will have two points of intersection with a general horizontal line (only one at the vertex).

B: a horizontal line, so will have an infinite number of points of intersection with a horizontal line.

D. A "V-shaped" graph that will generally have two points of intersection with a horizontal line (only one at the vertex).

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area f

myrzilka [38]

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 =

$A = \pi r^2$

where r is the radius of the circle.

Putting values, we get,

$1017.36 = 3.14 r^2\\\\r^2 = \dfrac{1017.36}{3.14}\\\\r^2 = 324\\r = \sqrt{324} = 18\text{ feet}$

Thus, the sprinkler can spread water 18 feet away.
