Step-by-step explanation:
In general, let denote the center of a given circle. Let
denote the radius of that circle. The standard equation for that circle would be:
.
The circle in this question is centered at .
is the
-coordinate of the center of this circle.
.
is the
-coordinate of the center of this circle.
.
The radius of this circle is . Therefore,
.
Hence, the standard equation for this circle would be:
.
The equation becomes y =-0.7x²+5.4x+6 if the person who is 6 feet tall throws a ball into the air option first is correct.
<h3>What is a quadratic equation ?</h3>Any equation of the form Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
The standard form of a quadratic equation:
Plug x = 0 and y = 6
6 = c ...(1)
Plug x = 1, and y = 10.7
10.7 = a + b + c ...(2)
Plug x = 2 and y = 14
14 = 4a + 2b + c ...(3)
After solving equation (1), (2) and (3) we get:
a = -0.7
b = 5.4
c = 6
Thus, the equation becomes y =-0.7x²+5.4x+6 if the person who is 6 feet tall throws a ball into the air option first is correct.
