Hi,

Please help with the following:

1)

Use basic identities to simplify sinks + cos'ssins. Enclose arguments of functions in parentheses. For example, sin (2x). Remember that writing sin(x) to the fourth power as she (2) is just a mathematical shorthand. You should write it as (sin (x)). which is what Mobius expects. sina + co- rains =Rewrite sin in terms of sins and cos r. Enclose arguments of functions in parentheses. For example, sin (2x). sinThe volume V of an ideal gas varies directly with the temperature ?" 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 95 liters and the temperature is increased to 320 degrees K Round your answer to two decimal places. The pressure is Number atmospheres.If a loading ramp is placed next to a truck, at a height of 3 feet, and the ramp is 23 feet long, what angle does the ramp make with the ground? Round your answer to one decimal place. The ramp makes an angle of Number degrees with the ground
