F(1)=3
f(n)=f(n−1)+5.5
f(3)=

f(3) = 14

Step-by-step explanation:

Using the recursive formula and f(1) = 3 , then

f(2) = f(1) + 5.5 = 3 + 5.5 = 8.5

f(3) = f(2) + 5.5 = 8.5 + 5.5 = 14

14

Step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
