Completing the squares, the correct statements regarding the equation of the circle are given by:
- The radius of the circle is 3 units
- The center of the circle lies on the x-axis.
- The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
<h3>What is the equation of a circle?</h3>
The equation of a circle of center and radius r is given by:
In this problem, the equation is given by:
x² + y² - 2x - 8 = 0.
Completing the squares:
(x - 1)² + y² = 8 + 1²
(x - 1)² + y² = 9.
Hence the center is (1,0), the radius is 3, and the correct statements are:
- The radius of the circle is 3 units
- The center of the circle lies on the x-axis.
- The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

Answer:
h(x) = -16 xx + 64 x + 8 , in Standard Form
Vertex at (2, 72) maximum height at 72 feet
Step-by-step explanation:
We have: h(x) = −16(x − 2)2 + 72
this function is in Vertex form.
the Standard form is when we expand out the expression.
h(x) = -16 *( x*x - 4x + 4) + 72
h(x) = -16 xx + 64 x - 64 + 72
h(x) = -16 xx + 64 x + 8
Vertex at (2, 72) maximum height at 72 feet
