3
may be I'm ryt confirm wih some others
Answer:
Length: 16
Width: 8
Step-by-step explanation:
W + W + L + L = P
8 + 8 + 16 + 16 = 48
48 = 48

![f(x) = -x^2-7x-6](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-x%5E2-7x-6)
As
,
.
This can be easily verified by looking at the graph (graph of a quadratic equation).
30.
The growth of a population is not linear, it's exponential.
31.
Exponential growth > polynomial, so
.

![V(t) = 30\cdot (25)^{\frac{t}{20}}](https://tex.z-dn.net/?f=V%28t%29%20%3D%2030%5Ccdot%20%2825%29%5E%7B%5Cfrac%7Bt%7D%7B20%7D%7D)
The question is asking V(t) for t = 40.
![V(40) = 30\cdot (25)^{\frac{40}{20}} \\~\\V(40) = 30\cdot 25^2 \\~\\V(40) = 30\cdot 625 \\~\\V(40) = 18750](https://tex.z-dn.net/?f=V%2840%29%20%3D%2030%5Ccdot%20%2825%29%5E%7B%5Cfrac%7B40%7D%7B20%7D%7D%20%5C%5C~%5C%5CV%2840%29%20%3D%2030%5Ccdot%2025%5E2%20%5C%5C~%5C%5CV%2840%29%20%3D%2030%5Ccdot%20625%20%5C%5C~%5C%5CV%2840%29%20%3D%2018750)

The point of symmetry of a quadratic equation
is at its vertice:
![V_x = \dfrac{-b}{2a}](https://tex.z-dn.net/?f=V_x%20%3D%20%5Cdfrac%7B-b%7D%7B2a%7D)
![V_x = \dfrac{6}{2}](https://tex.z-dn.net/?f=V_x%20%3D%20%5Cdfrac%7B6%7D%7B2%7D)
![V_x = 3](https://tex.z-dn.net/?f=V_x%20%3D%203)
The line is x= 3.
It's three to the power of four sevenths square inches.
Hope this will help you!
