The distance formula states that distance (d) is equal to the product of rate (r) and time (t). Which equation could be used to solve the problem?

A train traveled at a constant rate of 100 kmph. How many hours did the train take to travel 525 km?

t=525·100r

t=525100

t=100525

t=100·525

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

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.
