Answer:

756 ways

Step-by-step explanation:

Given

[tex]Counters = 28[/tex]

[tex]Selection = 2[/tex]

Required

Determine the number of ways

The first counter can be selected in 28 ways

The second can be selected in (28 - 1) ways

The number of selection is:

[tex]Selection = 28 * (28 -1)[/tex]

[tex]Selection = 28 * 27[/tex]

[tex]Selection = 756[/tex]

Hence, number of possible selection is 756

There 650 million CDs were sold in 2006 if there were 800 million  CDs sold in 2002, and there were 700 million  CDs in 2005 option (D) is correct.

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

From the graph:

(2002, 800) and (2005, 700)

We can draw a line for the best fit as follows:

[tex]\rm (y-800) = \frac{700-800}{2005-2002}(x-2002)[/tex]

[tex]\rm (y-800) = 33.33(x-2002)[/tex]

When x = 2006

[tex]\rm (y-800) = -33.33(2006-2002)\\[/tex]

y = 666.68

Which is near 650 million

Thus, there 650 million  CDs were sold in 2006 if there were 800 million  CDs sold in 2002, and there were 700 million  CDs in 2005 option (D) is correct.

Answer:

-4,-3,-2,-1,0,1

Step-by-step explanation:

First, doublepound and simplify it.

-15<3n

3n<6

Solve:

-5<n

n<2

Compound:

-5<n<2.

So the values are -4,-3,-2,-1,0,1

Hope this helps plz hit the crown :D

Answer:

The values of 'n' such that -15 < 3n ≤ 6 will be:

[tex]-5<n\le \:2[/tex]

[tex]-5<n\le \:2[/tex] can also be represented as: -4, -3, -2, -1, 0, 1, 2

Hence, the values of integer n will be:

Thus,

[tex]-15<3n\le \:6\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-5<n\le \:2\:\\ \:\mathrm{Interval\:Notation:}&\:(-5,\:2]\end{bmatrix}[/tex]

The line graph is also attached below.

Step-by-step explanation:

Given the expression

-15 < 3n ≤ 6

Lets us solve the inequality for n

[tex]-15<\:3n\le \:6[/tex]

Divide all parts by n

[tex]\:-\frac{15}{3}<\frac{3n}{3}\le \frac{6}{3}[/tex]

simplify

[tex]-5<n\le \:2[/tex]

Therefore, the values of 'n' such that -15 < 3n ≤ 6 will be:

[tex]-5<n\le \:2[/tex]

[tex]-5<n\le \:2[/tex] can also be represented as: -4, -3, -2, -1, 0, 1, 2

Hence, the values of integer n will be:

Thus,

[tex]-15<3n\le \:6\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-5<n\le \:2\:\\ \:\mathrm{Interval\:Notation:}&\:(-5,\:2]\end{bmatrix}[/tex]

Answer:

x = 1[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

As you can see, the two angles are supplementary as they lie on the same straight line so they should add up to 180°.

100 + 30x + 30x = 180

Evaluate like terms.

60x + 100 = 180

Isolate 60x.

60x = 180 - 100

       = 80

Find x.

x = 80 ÷ 60

x = 1[tex]\frac{1}{3}[/tex]

Answer:

y= (-7/8)x +7.5

Step-by-step explanation:

We know that the form for the equation of a line is

y= mx+b, with m being the slope, so our equation is

y=(-7/8)x+b. As b should be a constant, we need to find b. Plugging (12,-3) in, we have -3 = (-7/8)(12)+b =  -10.5+b. Adding 10.5 to both sides, we get b= 7.5, making our equation

y= (-7/8)x +7.5

Answer:

E

Step-by-step explanation:

We are given:

[tex]\ln(xy)=x-y[/tex]

And we want to find the second derivative at the point (1, 1).

So, we will take the derivative of both sides with respect to x:

[tex]\displaystyle \frac{d}{dx}\big[\ln(xy)\big]=\frac{d}{dx}\big[x-y\big][/tex]

Implicitly differentiate. The left will require the chain rule. Hence:

[tex]\displaystyle \frac{1}{xy}\cdot \frac{d}{dx}\big[xy\big]=1-\frac{dy}{dx}[/tex]

Differentiate:

[tex]\displaystyle \frac{1}{xy}\cdot \big( y+x \frac{dy}{dx} \big) =1-\frac{dy}{dx}[/tex]

Distribute:

[tex]\displaystyle \frac{1}{x}+\frac{1}{y}\frac{dy}{dx}=1-\frac{dy}{dx}[/tex]

Isolate the derivative term:

[tex]\displaystyle \frac{dy}{dx}\big(\frac{1}{y}+1\big)=1-\frac{1}{x}[/tex]

Divide:

[tex]\displaystyle \frac{dy}{dx}=\frac{1-\frac{1}{x}}{\frac{1}{y}+1}}[/tex]

Simplify. We can multiply both layers by xy. Hence:

[tex]\displaystyle\begin{aligned} \frac{dy}{dx}&=\frac{1-\frac{1}{x}}{\frac{1}{y}+1}}\cdot\frac{xy}{xy} \\ &=\frac{xy-y}{x+xy} \end{aligned}[/tex]

We can factor. Hence, our derivative is:

[tex]\displaystyle \frac{dy}{dx}=\frac{y(x-1)}{x(y+1)}[/tex]

Differentiate once more to find the second derivative:

[tex]\displaystyle \frac{d^2y}{dx^2}=\frac{d}{dx}\Big[\frac{y(x-1)}{x(y+1)}\Big][/tex]

Quotient rule:

[tex]\displaystyle \frac{d^2y}{dx^2}=\frac{\frac{d}{dx}[y(x-1)](x(y+1))-y(x-1)\frac{d}{dx}[x(y+1)]}{(x(y+1))^2}[/tex]

Differentiate using the product rule:

[tex]\displaystyle \frac{d^2y}{dx^2}=\frac{ \big[\frac{dy}{dx}(x-1)+y\big](x(y+1))-y(x-1)\big[(y+1)+x\frac{dy}{dx}\big] }{(x(y+1))^2 }[/tex]

You may choose to simplify, but this is not necessary, as we are only interested in the second derivative at (1, 1).

First, since first derivatives exist in our second derivative, we will find them first. Recall that the first derivative is given by:

[tex]\displaystyle \frac{dy}{dx}=\frac{y(x-1)}{x(y+1)}[/tex]

Therefore, at (1, 1), the first derivative is:

[tex]\displaystyle \frac{dy}{dx}_{(1, 1)}=\frac{1(1-1)}{1(1+1)}=\frac{1(0)}{1(2)}=0[/tex]

So, we will substitute 0 for every dy/dx for our second derivative. Thus:

[tex]\displaystyle \frac{d^2y}{dx^2}=\frac{ \big[(0)(x-1)+y\big](x(y+1))-y(x-1)\big[(y+1)+x(0)\big] }{(x(y+1))^2 }[/tex]

Simplify:

[tex]\displaystyle \frac{d^2y}{dx^2}=\frac{ y(x(y+1))-y(x-1)\big[(y+1)\big] }{(x(y+1))^2 }[/tex]

So, at the point (1, 1), our second derivative is:

[tex]\displaystyle \frac{d^2y}{dx^2}_{(1, 1)}=\frac{1(1(1+1))-1(1-1)(1+1)}{(1(1+1))^2}=\frac{2-0}{4}=\frac{1}{2}[/tex]

Hence, our final answer is E.

Answer:

he equation of the line is parallel to the given line and passing through the point C( 1,4) is        x - 8 y + 31=0

slope intercept form

                     [tex]y = \frac{x}{8} + \frac{31}{8}[/tex]

Step-by-step explanation:

Explanation:-

Given equation of the line  

                                y = 1/8x-4

                               8 y = x - 32

                         x - 8 y -32=0

The equation of the line is parallel to the given line a x + b y + k=0

                                                                                   x - 8 y + k=0

This line is passing through the point ( 1,4)

             x - 8 y + k=0

             1 - 32 + k =0

                  k = 31

The equation of the line is parallel to the given line and passing through the point C( 1,4) is        x - 8 y + 31=0

slope intercept form

                         8 y = x + 31

                          [tex]y = \frac{x}{8} + \frac{31}{8}[/tex]
