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:
Next use
product rule (I recommend watching videos if you're confused):
Next substitute you x-value (π/2) into your derivative:
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)
So we get our equation:
So our answer is E

With the ocean providing over half the oxygen we breathe and being a major source of food for the world’s population, there is a critical need for action and we all have the ability to make change.
Each year, at least eight million tonnes of plastics flow into the ocean — which is equivalent to dumping the contents of one garbage truck into the ocean every minute. If no action is taken, this is expected to increase to two per minute by 2030 and four per minute by 2050.
It’s sad to look at this picture and NOT look at how hurt sea animals are being hurt, how this WILL affect us in the near future, maybe even affecting us right now and we are too blind to notice. It’s painful to think of these things because sooo much is being lost. I hope people can open there eyes and realize the damage they are causing.
