Question

the expression 200 -16t^2 models the height in feet of an object that falls from an initial height of 200 feet t seconds after being dropped. Find the height of the object after 2.5 seconds.


In chemistry, Charles law states that if the pressure remains constant, the volume of an ideal gas varies directly with the temperature in degrees kelvin. suppose a gas has a volume of 100mL at 250 * K. which proportion could you use to find the volume V of the gas if the temperature decreases to 150*K?

Answer 1

first one, just plug in 2.5 for t and solve

2nd one, charles law is
\[\frac{V}{T}=\frac{V}{T}\]

Answer 2

t^2 not t
