Aplane flies at a speed of 300 mph how many miles does it fly in 5 hours

1500 miles

Step-by-step explanation:

We know that :

The formula we use to find the distance :

We are given ,

Speed of plane = 300 mph

Time taken to fly = 5 hours

Then, the distance covered by plane will be :-

Hence, the distance covered by plane = 1500 miles

if x = 1, then the answer is 3.5

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.
