Answer:

Our answer is $x=-2+\sqrt{2}$ .

Step-by-step explanation:

To solve for x, we need to isolate the variable. We can do so by subtracting 2 to both sides.

$x+2=\sqrt{2} \\x+2-2=-2+\sqrt{2} \\\\x=-2+\sqrt{2} \\$

Our answer is $x=-2+\sqrt{2}$ .

To find the decimal, calculate with a calculator.

You own 17 CDs. You want to randomly arrange 5 of them in a CD rack. What is the probability that the rack ends up in alphabetic

amid [387]

The probability that all five end up in alphabetical order is; 1/120.

<h3>What is the probability that the rack ends up in alphabetical order?</h3>

To evaluate the given probability; first, the number of possible arrangements is;

17P5 = 742,560 possible arrangements.

However, the chance of an alphabetical order arrangement in each case is; 1 out of 5! possible arrangements.

Hence, we have that the number of possible alphabetical arrangement is; (1/120) × 742,560 = 6188.

Hence, the required probability is; 6188/742,560 = 1/120

A rectangle is constructed with its base on the x-axis and two of its vertices on the parabola yequals25minusxsquared. What are

Karolina [17]

Answer:

The answer is " $\bold{\frac{32}{3}}\\$ "

Step-by-step explanation:

The rectangle should also be symmetrical to it because of the symmetry to the y-axis The pole of the y-axis. Its lower two vertices are (-x,0). it means that

and (-x,0), and (x,0). Therefore the base measurement of the rectangle is 2x. The top vertices on the parabola are as follows:

The calculation of the height of the rectangle also is clearly 16-x^2, (-x,16,-x^2) and (x,16,-x^2).

The area of the rectangle:

$A(x)=(2x)(16-x^2)\\\\A(x)=32x-2x^3$

The local extremes of this function are where the first derivative is 0:

$A'(x)=32-6x^2\\\\32-6x^2=0\\\\x= \pm\sqrt{\frac{32}{6}}\\\\x= \pm\frac{4\sqrt{3}}{3}\\\\$

Simply ignore the negative root because we need a positive length calculation

It wants a maximum, this we want to see if the second derivative's profit at the end is negative.

$A''\frac{4\sqrt{3}}{3} = -12\frac{4\sqrt{3}}{3}$

PLEASE HELP 20 POINTS

Step2247 [10]

Answer:

x = 20

Step-by-step explanation:

If a line is parallel to a side of a triangle and it intersects the other two sides then it divides those sides proportionally.

This is the case here thus

$\frac{11}{121}$ = $\frac{10}{5x + 10}$ ( cross- multiply )

11(5x + 10) = 1210

55x + 110 = 1210 ( subtract 110 from both sides )

55x = 1100 ( divide both sides by 55 )

x = 20

Choose true if the event is independent or false if the event is not independent.

True because it possible in anyway to get 6 and 1 if you roll a dice they not saying two of them they just saying 1 number cube so its a big chance that you can get 1 and 6
