Malik analyzed three samples to test which element was a metalloid. The table shows his results. A 7-column table with 3 rows. The first column titled element has entries A, B, C. The second column titled lustrous has entries yes, no, yes. The third column titled brittle has entries no, yes, yes. The fourth column titled how it reacts has entries base, acid, acid or base. The fifth column titled boiling point (degrees C) has entries not observed, negative 34. 04, not observed. The sixth column titled melting point (degrees C) has entries 97. 72, not observed, 1413. 85. The seventh column titled electrical conductivity has entries high, very low, medium. Which element (A, B, or C) is most likely a metalloid?.

The biologist has a second culture to examine. she knows that the population of the culture doubles every 15 minutes. after 1 hour and 15 minutes, her assistant found that 80,000 bacteria were present. a) what was the size of the initial population? b) predict the size of the culture at t=3 hours. what was the size of the population at 40 minutes? explain and justify your answers. c) create a graph of the population as a function of time. find an equation that can be used to predict the size of the population at any time t. d) examine the rate at which the bacteria culture is growing. how fast is the culture growing after 1 hour? after 1.5 hours? after 2 hours? use a time interval of h = 0.01 hours to estimate these rates. interpret these rates in terms of the context of the problem situation. how do these three rates compare?
