You are given a circle with a center at point (3,4) and a radius of r=4. What is the equation of this circle?
The equation of the circle is (x-3)+(y-4)=16.
You are in class, daydreaming in the middle of a lecture. Are you actually thinking?
Yes, daydreaming is just one example of the ways your brain is in a cognitive state, so even though your mind is on something else other than the lecture, you are still actually thinking.
y=(5x+4)/2. If x=2/3, what does y equal?
y=3.667, or y=11/3
