The area of the circle should be 201.06
7.8456 x 10^(-4)
this means you move the decimal place to the left 4 places to get the actual value
Answer:
800
Step-by-step explanation:
8*10*10=
8*10=
80*10=
800cm.
i broke up the problem. hope this helps!
The min or max of a parabola/quadratic function is the vertex
for
y=a(x-h)²+k
the vertex is (h,k)
so
vertex/min is at (-1,2)
h=-1
k=2
y=a(x-(-1))²+2
y=a(x+1)²+2
find a
given, (2,20) is on the graph
20=a(2+1)²+2
20=a(3)²+2
20=9a+2
minus 2 both sides
18=9a
divide by 9
2=a
y=2(x+1)²+2 is da equation
3rd one
f(x)=2(x+1)²+2
What r the options so i can get an idea
