1 Q Use basic identities to simplify 51:13 3 + {3052 $ slum. Enclose arguments of functions in parentheses. For example, Sl [2$]. Remember that writing sin(x) to the fourth power as 31114 [m] is just a mathematical shorthand. You should write it as (5111 (M) 4, which is what Mobius expects. sin3 a + cos.2 a sinm 2 IE E Rewrite sin in terms of sin and cosa. Enclose arguments of functions in parentheses. For example, sin (2x). sin =l 2 The volume V of an ideal gas varies directly with the temperature T and inversely with the pressure P. A cylinder contains oxygen at a temperature of 310 degrees K and a pressure of 18 atmospheres in a volume of 120 liters. Find the pressure if the volume is decreased to 100 liters and the temperature is increased to 330' degrees K. Round your answer to two decimal places. The pressure is atmospheres
