Calculus
Convert the polar equation to rectangular coordinates: r = 2-cos theta ...and find all points of vertical and horizontal tangency.
Calculus
Find the arc length of the curve described by the parametric equation over the given interval: x=t^(2) + 1 y=2t - 3 ...0 < t < 1
Calculus
On what intervals of t is the curve described by the given parametric equation concave up? Concave down? x=t^2; y=t^(3) + 3t I am a bit confused on how to solve this...any help/explanations are welcome!! (& greatly appreciated!)
Calculus
Convert the curve to an equation in rectangular coordinates: x=(t+2); y=-2sqrt(t)
Parametric Equations
Find the length of the curve over the given interval: x=t+1 y=ln cos(t) for t=0 ---> t=pi/4
calculus
Find the length of the curve over the given interval: x=t+1 y=ln cos(t) for t=0 ---> t=pi/4
Calculus
Convert to a rectangular equation by eliminating the parameter: x=sin(theta) y=(cos theta)^2

The Boeing 757-200 ER airliner carries 200 passengers and has doors with a height of 72 inches. Heights of men are normally distributed with a mean of 69 inches and a standard deviation of 2.8 inches. b) assume that half of the 200 passengers are men, what doorway height satis...
Math- Ms Sue can you help
so the volleyball team had a standard deviation 2.39 and a mean of 68.2 ( I messed up when giving you the numbers, there should have been a comma between 69 &70 not a period-giving 10 numbers) The dance team I got 3.05 standard deviation and a mean of 63 So the should the answ...
