The water level in a glass decreases 0.4 cm each hour due to evaporation. At the beginning of the experiment, the water level is 12.6 cm.
Let z represent time in hours, elapsed since the beginning of the experiment and let y represent the water level, in
centimeters.

20 points! asap! a is known to be 6,500 feet above sea level; ab = 600 feet. the angle at a looking up at p is 20°. the angle at b looking up at p is 35°. how far above sea level is the peak p? find the height of the mountain peak to the nearest foot. height above sea level =

8000 + 8800 + 8000 + 8 million + 80 trillion + another a katrillion equals

What are the coordinates of the point that is 1/3 of the way from a to b? a (2,-3) b (2,6)
