densk [106]

Answer:

90 minutes or 1.30 hours

Step-by-step explanation:

In 72 minutes, Sue ran 12 miles per hour

In 1 minute, Sue ran 12/72 miles per hour

In 60 minutes, Sue ran (12/72)*60 miles per hour

= 10 miles per hour

Remaining miles after completing 12 miles in 72 minutes = (24-12) = 12 miles.

If the mileage decreases to 2 miles per hour, he will now run = (10 - 2) = 8 miles per hour.

Now,

1 hour = 60 minutes

Sue can run 8 miles in 60 minutes

Sue can run 1 miles in 60/8 minutes

Sue can run 12 miles in (60/8)*12 minutes

= 90 minutes or 1.30 hours

Find DY divided by DX by implicit differentiation y=sinxy

amm1812

Answer:

Step-by-step explanation:

$y = sin(xy)\\\frac{d}{dx}y=cos(xy)(\frac{d}{dx}(xy))\\ \frac{d}{dx}y = cos(xy)(y + x*\frac{d}{dx}y)\\ write \: \frac{d}{dx}y \: as\:y'\\y' = cos(xy)(y+xy')\\y' = ycos(xy) + xy'cos(xy) \\y'-xy'cos(xy) = ycos(xy)\\y'(1-xcos(xy)) = ycos(xy)\\\\y' = \frac{ycos(xy)}{1-xcos(xy)}$
