B is not proportional because it does not go thru the origin
Answer:
The vertex would be (-1, -5).
Step-by-step explanation:
In order to find this, first find the x-coordinate of the vertex. You can do this by calculating out -b/2a in which a is the coefficient of x^2 and b is the coefficient of x.
-b/2a
-(-2)/2(-1)
2/-2
-1
So we know the x-coordinate to be -1. Now we plug that into the equation and find the y value.
-x^2 - 2x - 6
-(-1)^2 - 2(-1) - 6
-(1) + 2 - 6
-5
Answer:
18 feet
Step-by-step explanation:
Use Pyth Theorem
10^2 + 15^2 = c^2
100 + 225 = c^2
325 = c^2
18.027 = c
