Answer:
29
Step-by-step explanation:
2 solutions. This is because the parabola will cross the x axis twice. We know this because -5 means the vertex will be 5 units below the x axis. and the parabola opens upwards because the first coefficient is positive. Hope this helped :)

the lateral area of the hat is
.
<u>Step-by-step explanation:</u>
Here we have , George made a conical hat that has a slant height of 14 inches and a radius of 4 inches. The cone is open at one end. We need to find the nearest square unit , the lateral area of the hat . Let's find out:
We know that , Lateral area of cone =
⇒ ![Area = \pi rl](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20rl)
⇒ ![Area = \pi rl \left \{ {{r=4} \atop {l=14}} \right.](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20rl%20%5Cleft%20%5C%7B%20%7B%7Br%3D4%7D%20%5Catop%20%7Bl%3D14%7D%7D%20%5Cright.)
⇒ ![Area = \pi 4(14)](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20%204%2814%29)
⇒ ![Area = 56\pi](https://tex.z-dn.net/?f=Area%20%3D%2056%5Cpi)
⇒ ![Area = 56(3.14)](https://tex.z-dn.net/?f=Area%20%3D%2056%283.14%29)
⇒ ![Area = 175.84in^3](https://tex.z-dn.net/?f=Area%20%3D%20175.84in%5E3)
Therefore , the lateral area of the hat is
.
