Please help me too in if sin w=-0.5 and w is a degree measure in the third quadrant, find w.
MissTica
Do you remember your unit circle? If sin ω = was -1/2, then it would be 7<span>π/6. If you're unfamiliar with the unit circle, we can derive it.

So, you know that sin is OPPOSITE/HYPOTENUSE, and it's in the third quadrant, where x and y would be negative. If sin </span>ω = -1/2, that means that ω = 1/sin*(-1/2), or sin^(-1)*(-1/2). Let's ignore the negative for now and plug sin^(-1)*(-1/2) into your calculator in radians. You get (1/6)π. But that's in Quadrant 1. We want it in Quadrant 3.

In one complete revolution, or 360°, there are 2π radians. That means, if you want to rotate it 180°, you need to add π to what you originally got.
π+(1/6)π=(7/6)π.

I highly recommend you memorize the unit circle if you haven't already, because you'll need it from Precalculus on.

The attached graph is the drawn graph of given data

i) A teenager would spend exercising in one day if they spent 0.25 hours on social media.

0.9 hours

According to the graph if you locate the 0.25 hour on x-axis and draw perpendicular the will intersect the line on the value of y-axis is = 0.9 hours

ii) if they spent 1.38 hours on social media the corresponding value of exercising per day is approx  0

iii)   Yes it has the best fit value of corresponding values between two.  which is also reasonable in the all cases.  the nature of line is pure liner.
