A patient weighing 150 pounds requires a dose of 850 milligrams, while a patient weighing 300 lbs requires a dose of 1700 milligrams. Lab experiments have indicated that the concentration level C, in micrograms per milliliter (mcg/ml), of the medication in the a patient’s bloodstream as a function of the amount of time t, in hours, since the medication is administered is given by the quadratic function: C(t)= -1.152t^2 + 8.064t + 4.288. For a drug to have a beneficial effect, its concentration in the bloodstream must exceed a certain value, called the minimum therapeutic level. The minimum therapeutic level of Chloramphenicol is 8 mcg/ml.

Next Belle draws the question card, “ Of the four even numbers, how many different even numbers do you see?” She answers, “Three,” because she sees the 4, 6, and 8 on Andy and Dan's head. From this, Dan can conclude he has two even cards, since he can only see a 6 and Belle sees two more. http://www.jiskha.com/display.cgi?id=1322707099 http://www.jiskha.com/display.cgi?id=1322707003 We have figured out answer 1 BUT we cant figure out the steps to get it During gym class, the teacher gave students a number as they stood in line she counted 1, 2 and 3 then 1, 2 and 3 ......

At standard atmospheric pressure, the solid form of carbon dioxide called “dry ice” undergoes a phase change not to a liquid but straight to a gas. This process is called sublimation, and like other phase transitions heat energy is required. In this case it is the latent heat of sublimation, which for carbon dioxide is 573 kJ/kg at the sublimation temperature of ­78.5 °C. If 118 g of dry ice is dropped into 0.51 liters water at room temperature (20 °C), how much of the water will turn to ice by the time all the dry ice has sublimated? Note that when the dry ice becomes a gas, the gas bubbles out of the system. http://www.jiskha.com/display.cgi?id=1322704205 http://www.jiskha.com/display.cgi?id=1322704017 How do the senate and the house of representatives work together to pass bills into laws? http://www.jiskha.com/display.cgi?id=1322704017 http://www.jiskha.com/display.cgi?id=1322703972 Name the compound (CH3)2CHCCCH3 1. 2-methyl-3-pentyne 2. 3-methyl-1-pentyne 3. 5-methyl-2-pentyne 4. 4-methyl-2-pentyne 5. 3-methyl-2-hexane 6. 4-methyl-2-pentene Can you also explain how to draw the structure?
