HELP In a certain stretch of a train trip, rain falls vertically and the drops have a velocity of 8 m / s in relation to the ground. In this case, water marks are observed on the glass of one of the windows, tilted 37 ° vertically.

(additional information in the image)

According to the figure, the train moves at a speed of:

6 m/s, to the left

8 m/s, to the left

10 m/s, to the left

6 m/s, to the right

10 m/s, to the right

the answer is 31.27mph

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

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:
