Draw the graph of n=60/t

See attachment.

Step-by-step explanation:

The n axis is on the left (instead of y) and the t axis is the horizontal (in place of x).  As t approaches zero, n approaches either + infinity or - infinity, depending ion the direction zero is approached.  The graph is undefined as t = o (can't divide by zero).

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
