D) What fraction is equal to 50% of 1/4

An objects motion is described by the equation d= 4sin (pi t) what will the height of the object be at 1.75 seconds?

Sorry guys but as you have a small brain

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
