That answer looks the best to me because Hitler killed the Jews in the Holocaust due to their race and that is what the document is mainly about. He believed they were a problem and caused Germany to lose World War I.

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:

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

A series of coral reefs is located near a coastline. In 3–5 sentences, construct an argument about how people can help prevent e

Soloha48 [4]

Answer:

People can help prevent erosion to the coastline by limiting the construction of seawalls and sandbags that lead to beach erosion. Communities should preserve natural sand dunes, as they protect the coastlines from erosion. Man-made sand dunes actually do the opposite. It is important to consider that natural sand dunes are made of layers of different types of sand, which enables the wind to gather sand in a specific spot instead of reducing it, while also allowing vegetation to grow deeper and protect the coastline.

Hope this helps

Need opinions on this plzzz.

Is this comprehensive writing?

I must say if it is, it's great writing!

If not, is this your experience?

{And if it is, am so sorry. I can't say I understand what you're passing through but know that you and your siblings plus your mom are worth it. All the male parent figures that were supposed to be there and fufill their duties and didn't just know that what awaits them is God's payment. Trusting in God's Way will never let us down. Though life might look bleary and you said so that you don't know the future but that's the beauty of life only God knows. Therefore, pray without ceasing and trust in God and remember there are a lot of things to be thankful for your life, your mom, your siblings, your education, your bf.

(God is always saying something)

Much love to you. I pray everything gets better for you. The best is always yet to come.}

All the best! :)
