A marine biologist is preparing a deep-sea submersible for a dive. The sub stores breathing air under high pressure in a spherical air tank that measures 60.0 cm wide. The biologist estimates she will need 8100. L of air for the dive. Calculate the pressure to which this volume of air must be compressed in order to fit into the air tank. Write your answer in atmospheres. Be sure your answer has the correct number of significant digits. ? Check

Modeling Exponential Growth and Decay A biologist recorded a count of 360 bacteria present in a culture after 7 minutes and 1200 bacteria present after 20 minutes. a. To the nearest whole number, what was the initial population in the culture? The initial population was around bacteria. b. Rounding to four decimal places, write an exponential equation representing this situation. B(t) = c. To the nearest minute, how long did it take the population to double? The doubling time of...
