Consider the surface z = x 2+4y 2+1. Suppose you are walking on this surface directly above a curve C in the xy-plane, where the
Bess [88]

With x(t)=\cos t and y(t)=\sin t, we have

z(t)=x(t)^2+4y(t)^2+1

z(t)=\cos^2t+4\sin^2t+1

z(t)=3\sin^2t+2

Then z(t) has critical points where

\dfrac{\mathrm dz}{\mathrm dt}=6\sin t\cos t=3\sin2t=0

\implies\sin2t=0\implies2t=n\pi\implies t=\dfrac{n\pi}2

where n is any integer.

z(t) is increasing wherever \sin2t>0, which happens for

\dfrac{2n\pi}2

\boxed{n\pi

Valentin [98]

Answer:

The correct answer is 7.

Step-by-step explanation:

Let there be x number of candies in each bag filled by Ken and Mali.

Both Ken and Mali started with equal number of candies and put same number of candies in each bag.

Ken filled nine bags and had three candies left. Therefore total number of candies Ken had = 9x + 3.

Mali filled eight bags and had ten candies left. Therefore total number of candies Mali had = 8x + 10.

As both had equal number of candies in the beginning,

9x + 3 = 8x + 10

⇒ x  = 10 - 3 = 7

Thus each bag contained 7 candies.
