The graph of x^2=-2+y+5cosy is shown for y=11

erik [133]

(a)

We have been given an equation $x^{2}=-2+y+5cosy$ . Upon taking derivative of this equation with respect to x on both the sides, we get:

$2x=0+\frac{dy}{dx}+5(-siny)\frac{dy}{dx}\\2x=(1-5siny)\frac{dy}{dx}\Rightarrow \frac{dy}{dx}=\frac{2x}{1-5siny}$

(b)

In order to write the equation of tangent line, we need to find the slope of the line. We know that point (3,11) lies on the graph. Therefore, we write the slope of the tangent as:

$\text{Slope}=\frac{dy}{dx}=\frac{2(3)}{1-5sin(11)}=1$

Therefore, equation of tangent line is:

$y-y_{1}=m(x-x_{1})\Rightarrow y-11=1(x-3)\\y-11=x-3\\y=x+8$

(c)

We know that slope of tangent is given as $\frac{dy}{dx}=\frac{2x}{1-5siny}$ . The tangent will be vertical when denominator of slope is zero, that is:

$1-5siny=0\Rightarrow siny=\frac{1}{5}\Rightarrow y=arcsin(\frac{1}{5})\\y=1.732,1.525, 3.063 \text{ etc.}$

Why is productivity important to countries? Productivity matters because it produces a higher standard of living. Greater produc

NeX [460]

Well to understand productivity you must understand how humans started working for the benefit of themselves and community.
A long time ago there ware 4 simple roles a farmer, hunter or gatherer and solider all of which ware needed for basic survival. Then there was a revolution and these basic jobs became more and more unpopular and new jobs ware appearing through new discoveries. Now to make a simple meal we don't need to be a farmer and know hunter and gatherer we just go to store buy it and cook it. What is productivity? Productivity is a number of products made by a single person or bigger communities like country in certain amount of time. What that basically means is that we spend less time to produce. You might say this degrades the quality of products but it certainly increases each individual efficiency.

Zina [86]

Answer:

Explanation:

I pack carefully

( 1 ) While I’m on my way to pull over, I can signal and drive at the same speed I was before to avoid any collision.

I prepare to show everything

(2) After pulling over, I could turn on hazard lights, make sure I’m not in anyone’s way, prove that I’m not hiding anything by showing both my hands, and answering to everything the police officer says.

3) I roll down my window
