Answer:
radius is 7.16
Step-by-step explanation:
The equation to find the radius of a circle is r=C/2 with C being the circumference, r being the radius
First, list known values
Second, plug into equation
- r= 45/2
Third, Solve
- r= 7.16
- (Rounded to the hundredths)
I hope this helped and have a great day!
Answer:
i believe its 3 but i could be wrong
Step-by-step explanation:
sorry if i am..
no it is not, 590 millimeters = 59 centimeters
Ok
so the focus is on the opening side of the parabola
so for a vertex of (h,k)
opening up and down
(x-h)²=4p(y-k)
p is the distance from vertex to focus
it is also the distance from the vertex to the closes point on directix
2p=distance from focus to directix
p is positive if the focus is above the directix
ok
y=9 and (7,6)
9>6
directix is above the vertex
p is negative
find distance
from 9 to 6 is 3
3=2p
1.5=p
p is negative
and the vertex will be 1.5 above the focus and 1.5 below the directix
vertex is (7,7.5)
(x-7)²=4(-1.5)(y-7.5) is de equation
