Math
Okay, that seems really confusing. So in essence, I really just want to know how to find the equivalent expression using the related acute angle, tan110

Math
How would you figure it out using a Cartesian plane? And assuming you didn't know the answer was tan290, how would you get tan290 (because I'm supposed to arrive at the answer without knowing the answer..)?? Because the question is just asking for the equivalent expres...

Math
Use the rated acute angle to state an equivalent expression Tan110 The answer is tan290. Why isn't it 70? Please explain

psychology and the pursuit of happiness
Write a 700- to 900-word paper explaining the cultural and historical factors that contribute to this perspective. Contrast the traditional American perspective on happiness with the traditional Asian perspective on happiness. Format your paper consistent with APA guidelines.

physics
a child bounces a superball on the sidewalk. The velocity change of the superball is from 23m/s downward to 14m/s upward. if the contact time with the sidewalk is 1/800s, what is the magnitude of the average force exerted on the superball by the sidewalk?

Math
Ohh! Oh my goodness, thank you! I was subtracting it from the initial value (28000) this whole time and couldn't figure out what I was doing wrong. Thank you!!

Math
The value of a car after it is purchased depreciates according to the formula v(n)=28000(0.875)^n where v(n) is the car's value in the nth year since it was purchased. How much value does it lose in its fifth year? The answer is \$2052 but I don't see how; please explai...

Chemistry
A mixture of C3H8 and C2H2 has a mass of 2.0g . It is burned in excess O2 to form a mixture of water and carbon dioxide that contains 1.6 times as many moles of CO2 as of water. Find the mass of C2H2 in the original mixture.
