Use a calculator to determine angle x, rounded to the nearest degree. csc x = 1.25

A variant on the carousel at a theme park is the swing ride. Swings are suspeneded from a rotating platform and move outward to form an angle x with the vertical as the ride rotates. The angle is related to the radial distance,r, in metres, from the centr...

Solve the equation. Check for extraneous roots. 4^2x-4^x-20=0

Solve and check for extraneous roots. log_2x+log_2(x+2)=3 * _2 is a subscript and (x+2) isn't a superscript*

Calculate the energy released per gram of propane when it is burned in a combustion reaction. The chemical formula for propane is C3H8.

The question is asking to calculate the overall energy change in the combustion of ethane (C2H6). This is what I have done: The balanced equation: C2H6 + 6 O2 --> 2 CO2 + 3 H2O (6) 411 + 346 + (6) 494 --> (2) 799 + (3) 459 2466 + 346 + 2964 --> 1598 + 137...
