The amazing Larry is a human cannonball. He reaches a maximum height of 30 feet off the ground when he is 40 feet from the cannon. When he is shot from the cannon he is 12 feet above the ground. A) write an equation representing the height of the amazing Larry (in feet) ,y in terms of his distance (in feet) from the cannon x.

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
