4x2 + y2 = 36 Obtener dominio

Mathematics
1 answer:
Veronika [31]3 years ago
3 0

<em>Answer:</em>

<em>[-3,3]</em>

<em>Step-by-step explanation:</em>

<em>Write the problem as a mathematical expression.</em>

<em>4x^2+y^2=36</em>

<em>Subtract 4x^2 from both sides of the equation.</em>

<em>y^2=36-4x^2</em>

<em>Take the square root of both sides of the equation to eliminate the exponent on the left side.</em>

<em>y= + and - </em>\sqrt{36-4x^2}<em />

<em>The complete solution is the result of both the positive and negative portions of the solution.</em>

<em>y= </em>2\sqrt{(3+x)(3-x)<em />

<em />y= -2\sqrt{(3+x)(3-x)}<em />

<em>Set the radicand in </em>\sqrt{(3+x)(3-x)} \geq 0<em> greater than or equal to 0 to find where the expression is defined.</em>

<em />(3+x)(3-x)\geq 0<em />

<em>So your answer would be [-3,3]</em>

What is 39.79949748 rounded to the nearest hundredth?
Rufina [12.5K]

Answer:

Number = 39.80

Step-by-step explanation:

Given

Number = 39.79949748

Required

Approximate (to the nearest 100th)

This means that, we approximate at the second digit after the decimal.

So:

i.e,

Number = 39.79  [Begin  approximation] 949748

The first digit after [Begin approximation] is then approximated using the following rule:

0 - 4 \approx 0

5 - 9 \approx 1\\

Since 9 falls in 5 - 9 \approx 1\\ category, the number becomes:

Number = 39.[79+1]

Number = 39.80

Doss [256]

Answer:

\frac{1}{ {n}   +   {2}}

Step-by-step explanation:

\frac{n - 2}{ {n}^{2}  - 4}  \\  \\  =  \frac{n - 2}{ {n}^{2}  -  {2}^{2} } \\  \\  = \frac{n - 2}{ ({n}   +   {2})({n}  -  {2})} \\  \\  =  \frac{1}{ {n}   +   {2}} \\
