Differentiate. (assume k is a . y = 1 / (p + ke^p). i tried using the quotient (f/g)' = (gf' - fg') / g^2. and ended up with . (1-pke^(p-1)) / (p+ke^p)^2. which is apparently wrong.

Two cyclists 84 miles apart start riding toward each other at the same. one cycles 2 times as fast as the other. if they meet 4 hours later, what is the speed (in mi/h) of the faster cyclist?

Find cot x if sin x cot x csc x = √2

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
