The quadratic function shown graphed below has the form $(x)=(x+h)? +k. Determine the values of h and k.

Two fire-lookout stations are 190 miles apart, with station a directly south of station b. both stations spot a fire. the bearing of the fire from station a is upper n 55 degrees upper e and the bearing of the fire from station b is upper s 60 degrees e. how far, to the nearest tenth of a mile, is the fire from each lookout station?

You can find the constant of proportionality by finding the ratio of

Average acceleration: i have no idea how to do this.
