Acurve is defined by the parametric equations below. x = t cos(u) u du 1 y = t sin(u) u du 1 find the length of the arc of the curve from the origin to the nearest point where there is a vertical tangent line.

What are the related frequencies to the nearest hundredth of the columns of the two way table? group 1: a-102 b-34group 2: a-18 b-14edited: i don’t have all day to be waiting for an answer. i figured it out.

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Evaluate the expression for the given value of the variable. ∣-4b-8∣+∣-1-b^2 ∣+2b^3 ; b=-2
