Answer:
![p(5) = - 5 \\ p(0) = 5 \\ p( - \frac{1}{2} ) = 6](https://tex.z-dn.net/?f=p%285%29%20%3D%20%20-%205%20%5C%5C%20p%280%29%20%3D%205%20%5C%5C%20p%28%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%29%20%3D%206)
Step-by-step explanation:
![p(x) = - 2x + 5](https://tex.z-dn.net/?f=p%28x%29%20%3D%20%20-%202x%20%2B%205)
We substitute x = 5,0 and - 1/2 in the equation.
![p(5) = - 2(5) + 5 \\ p(5) = - 10 + 5 \\ p(5) = - 5](https://tex.z-dn.net/?f=p%285%29%20%3D%20%20-%202%285%29%20%2B%205%20%5C%5C%20p%285%29%20%3D%20%20-%2010%20%2B%205%20%5C%5C%20p%285%29%20%3D%20%20-%205)
![p(0) = - 2(0) + 5 \\ p(0) = 0 + 5 \\ p(0) = 5](https://tex.z-dn.net/?f=p%280%29%20%3D%20%20-%202%280%29%20%2B%205%20%5C%5C%20p%280%29%20%3D%200%20%2B%205%20%20%5C%5C%20p%280%29%20%3D%205)
![p( - \frac{1}{2} ) = - 2( - \frac{1}{2} ) + 5 \\ p( - \frac{1}{2} ) = 1 + 5 \\ p( - \frac{1}{2} ) = 6](https://tex.z-dn.net/?f=p%28%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%29%20%3D%20%20-%202%28%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%29%20%2B%205%20%5C%5C%20p%28%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%29%20%3D%201%20%2B%205%20%5C%5C%20p%28%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%29%20%3D%206)

Answer:
5√(7)m or 13.23m its D
Step-by-step explanation:
use pythagorean theorem
a²+b²=c²
c=20
b=15
a²+225=400
a²=175
√(175) = 5√(7) = 13.23
