Consider the following. x = sinh(t), y = cosh(t) (a) eliminate the parameter to find a cartesian equation of the curve. (b) sketch the curve and indicate with an arrow the direction in which the curve is traced as the parameter increases.

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.

17,000 is the correct answer.
