Answer:
The diameter is 6 yards.
Step-by-step explanation:
2pir=18.84
pir=9.42
r=3(nearest whole number)
d=2r
d=2*3
d=6
Therefore, the diameter is 6 yards.
(If It's a number like this: 8/9 then it's a fraction)
Answer:
<h2><em><u>
9. -2/6</u></em></h2><h2><em><u>
10. -6/-10</u></em></h2><h2><em><u>
11. 3/4</u></em></h2>
Step-by-step explanation:
Yay, I love doing these!
9.} 6 - 8 and 4- -2= -2/6
10.} 3 - 9 and -1 - 9= -6/-10
11.} -1 - -7 and 5 - -3= 6/8 simplify it by 2= 3/4
Answer:
![(x+4)^2=28(y-3)](https://tex.z-dn.net/?f=%28x%2B4%29%5E2%3D28%28y-3%29)
Step-by-step explanation:
The directrix of the parabola is the horizontal line with the eqaution
The focus of the parabola is at point (-4,10), than the axis of symmetry of the parabola is the perpendicular line to the directrix passing through the focus. Its equation is
The distance between the directrix and the focus is
so
and the vertex is at point ![\left(-4,10-\dfrac{14}{2}\right)\rightarrow (-4,3)](https://tex.z-dn.net/?f=%5Cleft%28-4%2C10-%5Cdfrac%7B14%7D%7B2%7D%5Cright%29%5Crightarrow%20%28-4%2C3%29)
Parabola goes in positive y-direction, hence its equation is
![(x-x_0)^2=2p(y-y_0),](https://tex.z-dn.net/?f=%28x-x_0%29%5E2%3D2p%28y-y_0%29%2C)
where
is the vertex, so the equation of this parabola is
![(x+4)^2=28(y-3)](https://tex.z-dn.net/?f=%28x%2B4%29%5E2%3D28%28y-3%29)
