The population of a city is modeled by the equation P(t) = 253,195e0.25t where t is measured in years. If the city continues to grow at this rate, in approximately how many years will it take for the population to reach one million? (Round your answer to two decimal places.) yr

When a skydiver jumps from an airplane, his downward velocity, in feet per second, before he opens his parachute is given by  v = 176(1 − 0.834t ),  where t is the number of seconds that have elapsed since he jumped from the airplane. What is the velocity after 6 seconds? (Round your answer to two decimal places.) ft/s

The air in a room 15 ft by 12 ft by 12 ft is 3% carbon monoxide. Starting at t=0, fresh air containing no carbon monoxide is blown into the room at a rate of 300 ft/min. If air in the room flows out through a vent at the same rate, when will the air in the room be 0.01% carbon monoxide? The air in the room will be 0.01% carbon monoxide after (Round to two decimal places as needed.) minutes.

Suppose that Tammy's blood pressure can be modeled by the following function. p (t) = 91 + 24 cos (89 nt) 同 Tammy's blood pressure increases each time her heart beats, and it decreases as her heart rests in between beats. In this equation, p(t) is the blood pressure 00 in mmHg (millimeters of mercury), and t is the time in minutes. 民 Find the following. If necessary, round to the nearest hundredth. Amplitude of p : mmHg Number of heartbeats per minute: Period of p : minutes Save For Later Submit Assignment Check 2021 McGraw-Hili Ecucation. AlI Rights Reserved. Terms of Use Privacy Accessibility
