Answer:
![\large\boxed{(x+5)^2+y^2=64}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%28x%2B5%29%5E2%2By%5E2%3D64%7D)
Step-by-step explanation:
The standard form of an equation of a circle:
![(x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
(h, k) - center
r - radius
We have the center (-5, 0) and the radius r = 8. Substitute:
![(x-(-5))^2+(y-0)^2=8^2\\\\(x+5)^2+y^2=64](https://tex.z-dn.net/?f=%28x-%28-5%29%29%5E2%2B%28y-0%29%5E2%3D8%5E2%5C%5C%5C%5C%28x%2B5%29%5E2%2By%5E2%3D64)
3/4 = 0.75
1/2 = 0.5
Area = l * w
100.75 * 75.5 = 7,606.625
Answer = 7,606.625 ft
Answer:
21 times
Step-by-step explanation:
Given
![P(3) = 50 \%](https://tex.z-dn.net/?f=P%283%29%20%3D%2050%20%5C%25)
![n =42](https://tex.z-dn.net/?f=n%20%3D42)
Required
The least number of times to land on 3
This is calculated using:
![Least = n * P(3)](https://tex.z-dn.net/?f=Least%20%3D%20n%20%2A%20P%283%29)
![Least = 42 * 50\%](https://tex.z-dn.net/?f=Least%20%3D%2042%20%2A%2050%5C%25)
![Least = 21](https://tex.z-dn.net/?f=Least%20%3D%2021)
