.44444444
Step-by-step explanation:
πr²=full circumference
18/π(9)²=x/2π
the numbers are 30x ,like 30*2=60
Range is ouput
testing limints
basically see the vertices
y=a(x-h)^2+k
(h,k) is vertex
also, when a is negative, graph opens down
when a is positive, graph opens up
y<u><</u>5
k musbe 5
eliminate last 2
since less than, must open down
negative a
second one
f(x)=-(x-4)^2+5 is ansre
