    Quadratic equation solving with constraint.

    Thanks so much! This is exactly what was messing me up. Dono why I didn't think of that. Thanks again!
  2. Q

    Quadratic equation solving with constraint.

    Homework Statement So I've worked this problem for awhile. Its a several page of math problem with optimization, legrangians, cramers rule, etc to get to this point. All I need to do now is by hand solve this equation for x and y with the constraint. Homework Equations -0.03x^2 + 40x...

    A REDICULOUSLY hard questions about building a temperature model

    Im majorly confused. I have attached a sheet of my calculations. If you could just point out my error I would like to fix it.
  4. Q

    A REDICULOUSLY hard questions about building a temperature model

    How would you integrate the p^2 since there is no variable for that integration?
  5. Q

    A REDICULOUSLY hard questions about building a temperature model

    The same ones I used for part one? 2pi over 0 and pi over 0?
  6. Q

    A REDICULOUSLY hard questions about building a temperature model

    I do not believe so. I am totally lost for parts 3, 4, & 5.

    A REDICULOUSLY hard questions about building a temperature model

    I am having difficulty figuring out both unfortunately.
  9. Q

    A REDICULOUSLY hard questions about building a temperature model

    Please help. I need this answered by tomorrow morning. The question is: Compute the average temperature over the Earth's surface given the fact that the Earth is a sphere with radius a=p. The temperature model is given by the linear transformation T=2(deg)+85sin(φ), with a 90deg rotation...

    How to Calculate M in a Simple Math Equation

    Please break down how this solution was reached for me. -3.2=-M(5)e^-((0.025)(.8))[377cos(377*0.08)-(0.025)sin(377*0.8)] M=1.73 Thank you soo much!
  11. Q

    Simple math im not understanding

    Shouldn't it be 220*10^-3/(6/4.9)=x lnx=lne^... lne^/lnx =ans??
  12. Q

    Simple math im not understanding

    When I divide 220*10^-3 I don't get the same answer.
  13. Q

    Simple math im not understanding

    Heres the solution I have: 220*10^-3=(6/4.9)(1-e^((-t*4.9)/(140*10^-3)) e^(-4.9t/(140*10^-3))=08203 t=5.658 Could somebody expand this more for me please so I can see the mathematical operations to get to this solution?
