For a project in his Geometry class, Chase uses a mirror on the ground to measure the height of his school's football goalpost. He walks a distance of 7.25 meters from the
goalpost, then places a mirror flat on the ground, marked with an X at the center. He
then walks 6.55 more meters past the mirror, so that when he turns around and looks
down at the mirror, he can see the top of the goalpost clearly marked in the X. His
partner measures the distance from his eyes to the ground to be 1.45 meters. How tall
is the goalpost? Round your answer to the nearest hundredth of a meter.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

i'm not really sure how to answer that

step-by-step explanation:

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,

13 / 13 = 1 mph
