Answer:
<h3> (x-8)²+(y-3)² = 81</h3>
Step-by-step explanation:
The general equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the centre of the circle
r is the radius
Given the centre (8, 3) and the radius of 9, the equation of the circle will be;
(x-a)²+(y-b)² = r²
(x-8)²+(y-3)² = 9²
(x-8)²+(y-3)² = 81
hence the required equation is (x-8)²+(y-3)² = 81
Answer:
f(5) = 136.71875
Step-by-step explanation:
f(5) if f(1)=3.5 and f(x+1)=5\2 f(x)
f(2) = (5/2)* f(1) = (5/2)* 3.5 = 8.75
f(3) = (5/3)*f(2) =(5/2) * 8.75
f(4) = (5/3)*f(3) =(5/2)*(5/2) * 8.75
f(5) = (5/3)*f(4) = (5/3)*(5/2)*(5/2) * 8.75
f(5) = (5/2)^4 * 3.5 = (625/16) * 3.5 = 136.71875
f(5) = 136.71875
Answer:
9
Step-by-step explanation:
Exterior sides = 180 - 140 = 40
number of sides = 360 / 40 = 9 sides
The formula for axis of symmetry is -b/2a.
For f(x):
0/2(4)
0/8
Axis of symmetry= 0
For g(x)
-(-8)/2(1)
8/2
Axis of symmetry= 4
For h(x)
-(-12)/2(-3)
12/-6
Axis of symmetry= -2
Order from least to greatest: -2, 0, 4
Final answer: h(x), f(x), g(x)
