2 Write the equation of the line that goes

FromTheMoon [43]

if the twi lines are parallel , they have the same slope.

So slope is 1/2.

equation of a line is : mx +p

The line goes throught (-2 ; 4)

We have 1/2 ( -2) + p = 4

- 2/2 +p = 4

-1 +p = 4

p = 4+1

p = 5

equation of the line is y = 1/2x +5

On the graph of f(x)=cos x and the interval [0,2π), for what value of x does f(x) achieve a minimum?

Mariulka [41]

Answer:

$cos(\pi)=-1$

Step-by-step explanation:

$f(x)=cos (x)$

State that the values where cos x is minimum:

$x=\pi +2\pi n, n\in \mathbb{Z}$

$cos(0)=1\\$

$cos\left(\frac{\pi}{4} \right)=\frac{\sqrt{2} }{2}$

$cos\left(\frac{\pi}{2} \right)=0$

$cos(\pi)=-1$

$cos\left(\frac{3\pi}{2} \right)=0$

Describe how to transform

$\bf ~\hspace{7em}\textit{rational exponents} \\\\ a^{\frac{ n}{ m}} \implies \sqrt[ m]{a^ n} ~\hspace{10em} a^{-\frac{ n}{ m}} \implies \cfrac{1}{a^{\frac{ n}{ m}}} \implies \cfrac{1}{\sqrt[ m]{a^ n}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \left( \sqrt[6]{x^5} \right)^7\implies \sqrt[6]{(x^5)^7}\implies \sqrt[6]{x^{5\cdot 7}}\implies \sqrt[6]{x^{35}}\implies x^{\frac{35}{6}}$

June is 16 less than 11 times the average number of tornado's in december

Lyrx [107]

Answer:

The average number of tornado's in December is 22 and the average number of tornado's in June is 226

Step-by-step explanation:

<u><em>The complete question is</em></u>

The average number of tornado's in June is 16 less than 11 times the average number of tornado's in December. If the difference between the average number of tornado's in June and December is 204,determine the average number of tornado's in December and June.

Let

x ----> the average number of tornado's in June

y ----> the average number of tornado's in December

we know that

$x=11y-16$ ---> equation A
