The minimum or the vertex is -2
by using the rule -b/2a
-8/4=-2
Answer:
64
Step-by-step explanation:
![(6+1/3x)^2](https://tex.z-dn.net/?f=%286%2B1%2F3x%29%5E2)
Lets first substitute x into the equation:
![(6+1/3[6])^2](https://tex.z-dn.net/?f=%286%2B1%2F3%5B6%5D%29%5E2)
1/3 times 6 = 2
![(6+2)^{2}](https://tex.z-dn.net/?f=%286%2B2%29%5E%7B2%7D)
![8^{2}](https://tex.z-dn.net/?f=8%5E%7B2%7D)
Which equals 64
You would just do the area which is L*W so 9*13 = 117 ft squared
The answer is 2,16 i’m pretty sure
Answer:
d ≈ 21.26 units
Step-by-step explanation:
calculate the distance d using the distance formula
d = ![\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E2%2B%28y_%7B2%7D-y_%7B1%7D%29%5E2%20%20%20%20%7D)
with (x₁, y₁ ) = (- 3, 8 ) and (x₂, y₂ ) = (13 - 6 )
d = ![\sqrt{13-(-3))^2+(-6-8)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B13-%28-3%29%29%5E2%2B%28-6-8%29%5E2%7D)
= ![\sqrt{(13+3)^2+(-14)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%2813%2B3%29%5E2%2B%28-14%29%5E2%7D)
= ![\sqrt{16^2+196}](https://tex.z-dn.net/?f=%5Csqrt%7B16%5E2%2B196%7D)
= ![\sqrt{256+196}](https://tex.z-dn.net/?f=%5Csqrt%7B256%2B196%7D)
= ![\sqrt{452}](https://tex.z-dn.net/?f=%5Csqrt%7B452%7D)
≈ 21.26 units ( to 2 dec. places )
