Answer:

Heat will flow from the tea into the air in the room.

Explanation:

Since the temperature in the room it is almost impossible that the cup of tea would warm up the room, and the heat from the tea cup will only flow from the tea cup to the air in the room that is at 24º, actually making almost no difference on the temperature of the room, and making it just slightly hotter. But with no considerable change on the room´s temperature.

The equations of the tangent to the curve y=xsinx at the point (pi/2,pi/2) is

never [62]

The first thing you have to realize is that tangent is the slope of a curve on a given point. You can solve for the slope by finding the derivative of the given function. So:

$\frac{d}{dx} xsin(x)$

Next use product rule (I recommend watching videos if you're confused):

$= [sin(x)] + [x*cos(x)]$

Next substitute you x-value (π/2) into your derivative:

$= [sin( \frac{ \pi}{2} )] +[ \frac{\pi}{2}*cos( \frac{\pi}{2})]$
$= 1 + \frac{\pi}{2} *0$
$= 1$

So our slope at π/2 is 1. Next we use our slope-form and substitute our given value and solve for y-intercept (algebra-stuff)

$( \frac{\pi}{2}) = 1( \frac{\pi}{2}) + b$
$b = 0$

So we get our equation:

$y = x$

So our answer is E
