<h3><u>
Answer:</u></h3>
The number of x-intercepts of the function are:
Two(2)
<h3><u>
Step-by-Step explanation:</u></h3>
The domain of a quadratic function is all real numbers and the range is y ≤ 2.
i.e. the graph of this quadratic polynomial will be a downward parabola whose vertex has y-coordinates less than or equal to 2.
Also we know that any upward or downward facing parabola have two x-intercepts i.e. the parabola crosses the x-axis at two points i.e. the y-coordinates of those two points are zero.
Hence, the number of x-intercepts of the function is:
Two(2)
Answer:
13.76ft²
Step-by-step explanation:
Side of square: d=8ft
Area of board: Sb=d×d=64ft²
Area of circle: Sc=pi×r²=pi×(d/2)²=pi×d²/4=pi×64/4= 16×pi=50.24ft²
Remainin area: Sb-Sc=64-50.24=13.76ft²
