Answer:
see explanation
Step-by-step explanation:
(a)
To find the x- intercepts , let y = 0 , that is
6x - x² = 0 ← factor out x from each term
x(6 - x) = 0
Equate each factor to zero and solve for x
x = 0
6 - x = 0 ⇒ x = 6
Coordinates of P (6, 0 )
(b)
The axis of symmetry is a vertical line, positioned at the midpoint of the zeros
x = 
= 
= 3
Equation of axis of symmetry is x = 3
(c)
Given a parabola in standard form y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
= - 
y = 6x - x² = - x² + 6x ← is in standard form
with a = - 1, b = 6 , then
= - 
= 3
Substitute x = 3 into y = 6x - x² for y- coordinate
y = 6(3) - 3² = 18 - 9 = 9
coordinates of maximum point = (3, 9 )

Answer:
17.0 in
Step-by-step explanation:
The arc RS is calculated as
RS = circumference of circle × fraction of circle
= 2πr × 
= 2 × 3.14 × 6.48 × 
≈ 17.0 in ( to the nearest tenth )
You have to move the decimal point all the way to behind the 9.
You move it eleven places to the right.
The answer is
9.3 x 10^-11
367 it’s also equivalent to 338
