physics
Ab = V²/2x = -88²/(2*146) = -26.52 ft/sec² Aa = 2x/t² = 2(5280/4)/19.9² = 6.666 ft/sec² V = √[2ax] = √[2*6.666*5280/4] = 132.658 ft/sec = 90.4 mph t = √[2x/a] = √[2*5280/(4*26.52)] = 9.98 sec

but one of those false true trues are wrong, just don't know which one

Math: partial derivative
z=u(v+w)^(1/2) find ∂^3z/(∂u∂v∂w) what partial derivative am I suppose to be finding exactly? Do I take the derivative of z three times? Please help. Thank you.

math 12
While training for a race, a runner increases her distance by 10% each day. If she runs 2km on the first day, what will her total distance for 26 days of training?

statistics
Considering that a researcher can test at the <p = .05 (95%), p = .01 (99%), or p = .001 (99.9%) level for statistical significance, how would you use these three levels in relationship to risk to patients in implementing the decisions of your research?

Math
Determine whether the given conditions are sufficient to prove that ∆PQR ∆MNO.Justify your answers. PQ≅MN,PR≅MO,QR≅NO I have no idea how to do this! Can anyone help me. Thank you
