Answer:
Area= 615 ft²
Step-by-step explanation:
Apply the formula for area of a circle to find the area watered when a sprinkler covers a full circle
Area of a circle= 
r= 14ft
Area= 3.14 × 14²
Area=615.44 ft²
Area= 615 ft²
The form of quadratic representing the roots can be expressed as,

Where p and q are the roots of the equation.
The form which represents the zeroes of function h is,

Where 2 and -2 are the roots of the function h(x).
Thus, option (B) is correct.
Answer:
Area of the triangle is 10 square units
Step-by-step explanation:
Recall that the formula for the area of a triangle is: "base x height / 2", and in this case, we can consider the triangle's base as the segment that joins the vertices (5, 4) and (5, 8) which gives a segment length of 4 units. The height of the triangle is then the distance between the third vertex (0,7) and the base, which is exactly 5 units. Then the area becomes:
Area = 4 x 5 / 2 = 10 square units.
Y=14x+9 the values x=1,2,3
