Answer:
I'm going to write both of these because maybe you have a fill in the blank question. I don't know.
![(x-4)^2+(y-5)^2=9^2](https://tex.z-dn.net/?f=%28x-4%29%5E2%2B%28y-5%29%5E2%3D9%5E2)
Simplify:
![(x-4)^2+(y-5)^2=81](https://tex.z-dn.net/?f=%28x-4%29%5E2%2B%28y-5%29%5E2%3D81)
Step-by-step explanation:
is the equation of a circle with center (h,k) and radius r.
You are given (h,k)=(4,5) because that is the center.
You are given r=9 because it says radius 9.
Let's plug this in.
![(x-4)^2+(y-5)^2=9^2](https://tex.z-dn.net/?f=%28x-4%29%5E2%2B%28y-5%29%5E2%3D9%5E2)
Simplify:
![(x-4)^2+(y-5)^2=81](https://tex.z-dn.net/?f=%28x-4%29%5E2%2B%28y-5%29%5E2%3D81)
The only ways i thought of was 0.7, 0.70, and 0.700 .
Answer:
Q1) (x+7)² = 9
x = -10, -4
Q2) (x-8)² = 144
x = -4, 20
Q3) (x-1)² = 81
x = -8, 10
Step-by-step explanation:
Q1) x² + 14x + 49 = 9
x² + 2(x)(7) + 7² = 9
(x + 7)² = 9
x + 7 = +/- sqrt(9)
x + 7 = 3
x = -4
x + 7 = -3
x = -10
Q2) x² - 16x + 64 = 144
x² - 2(x)(8) + 8² = 144
(x - 8)² = 144
x - 8 = +/- sqrt(144)
x - 8 = 12
x = 20
x - 8 = -12
x = -4
Q3) x² - 2x + 1 = 81
x² - 2(x)(1) + 1² = 81
(x - 1)² = 81
x - 1 =+/- sqrt(81)
x - 1 = 9
x = 10
x - 1 = -9
x = -8
Given
![h=P(t)=-16t^2+1450](https://tex.z-dn.net/?f=h%3DP%28t%29%3D-16t%5E2%2B1450)
Evaluate P(5), as shown below
![\begin{gathered} P(5)=-16*5^2+1450 \\ \Rightarrow P(5)=-400+1450=1050 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20P%285%29%3D-16%2A5%5E2%2B1450%20%5C%5C%20%5CRightarrow%20P%285%29%3D-400%2B1450%3D1050%20%5Cend%7Bgathered%7D)
Therefore, the answer is 1050ft.
