Three times the sum of a number and two is equal to -9.

Suppose that So, S1, S2,... is a sequence of subsets of N the following sets is guaranteed to be different from all sets in the sequence is S = {n² | n² & Sn}.

Subsets are a part of the mathematical concept of sets. A set is anything that is wrapped in curly braces, such as "a,b,c,d." If set A is a collection of even integers and set B is composed of the numbers 2, 4, and 6, then set A is the superset of set B and set B is said to be a subset of set A. Review Sets Subset and Superset for further details.

Set A is referred to as a subset of Set B if each element of Set A is also present in Set B. In other words, Set B includes Set A.

As an illustration, if set A has the elements X, Y, and set B contains the elements X, Y, and Z, then set A is the subset of set B.

Answer:

Health and Disability

Step-by-step explanation:

I just took the test and I got this question right.

The values are x = 2 and NS = 3.5.

Given is a circle with center S, we need to find the missing measure,

K = 16, MP = 8, LP = 2x+4, and PS = 3.5, we need to find the measures of x and NS.

We know that the perpendicular drawn from the center of a circle bisect the chords into two halves,

And the perpendiculars are congruent.

Therefore,

MP = PL

2x+4 = 8

x+2 = 4

x = 2

Also,

NS = PS

So, NS = 3.5

Hence the values are x = 2 and NS = 3.5.

Answer:

2,3,4,5,6 is the domain

4,6,8,10,12 is the range

Step-by-step explanation:

Answer:

The domain is {2,3,4,5,6} and the range is {4,6,8,10,12}.

Step-by-step explanation:

For part (a), we need to find the derivative of the supply equation with respect to the number of units, x.

The supply equation is given by:

S(x) = 30 + 90p * In(4x + 5)

To find the derivative of S(x) with respect to x, we can use the chain rule:

\(\frac{dS(x)}{dx} =\frac{dS(x)}{dp}*\frac{dp}{dx}\)

Since the derivative of S(x) with respect to p is 90 * In(4x + 5), we can substitute this into the equation above:

\(\frac{dS}{dx}=(90*ln(4x+5))*(\frac{dp}{dx} )\)

This gives us the expression for the rate of change of supply price with respect to the number of units supplied.

For part (b), we need to find the rate of change of supply price when the number of units is 30. Substituting x = 30 into the equation above gives us:

\(\frac{Ds(30)}{dx} = (90*ln(4*30+5))*\frac{dp}{dx}\)

For part (c), we need to approximate the price increase associated with the number of units supplied changing from 30 to 31. To do this, we can use the equation from part (a) to find the rate of change of supply price with respect to the number of units supplied and then multiply this rate by the change in the number of units (from 30 to 31).

The approximate price increase is given by:

\(\frac{dS(x)}{dx} *(x2-x1)=\frac{dS(x)}{dx}*(31-30)\)

Substituting the appropriate values into this equation will give us the approximate price increase associated with the number of units changing from 30 to 31.

Answer:

Area of one side of mini DVD = 15π or 47.12 cm²

Step-by-step explanation:

The radius of the mini DVD is;r = 4cm.

Area of a circle = πr²

Thus, Area of mini DVD = π × 4² = 16π

Now,we are told the mini DVD has a hole with a radius of 1 cm.

Area of hole = π × 1² = π

To find the area of one side of the mini DVD, we have to subtract the area of the hole from the area of the DVD.

Thus;

Area of one side of mini DVD = 16π - π

= 15π = 47.12 cm²

A ={(4), (5)}

Step-by-step explanation:

Given that:

Among the three copies, (1,2,3) are the first printings, and (4,5) are the second printings.

A student who examines these books in random order stops when a second printing has been selected.

Thus, we can compute the sample space associated with these experiments as:

S = { (4), (5), (1,4), (1,5), (2,4), (2,5), (3,4), (3,5), (1,2,3,4), (1,2,3,5), (2,1,3,4) (2,1,3,5), (3,1,2,4), (3,1,2,5) }

Suppose A represents the event that we must examine exactly one book.

Then the outcomes of A are:

Step-by-step explanation:

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

\(y=\stackrel{\stackrel{m}{\downarrow }}{-13}x+8\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill\)

\(\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{ -13 \implies \cfrac{-13}{1}} ~\hfill \stackrel{reciprocal}{\cfrac{1}{-13}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{1}{-13} \implies \cfrac{1}{ 13 }}}\)

so we're really looking for the equation of a line whose slope is 1/13 and it passes through (3 , 8)

\((\stackrel{x_1}{3}~,~\stackrel{y_1}{8})\hspace{10em} \stackrel{slope}{m} ~=~ \cfrac{1}{13} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{8}=\stackrel{m}{ \cfrac{1}{13}}(x-\stackrel{x_1}{3}) \\\\\\ y-8=\cfrac{1}{13}x-\cfrac{3}{13}\implies y=\cfrac{1}{13}x-\cfrac{3}{13}+8\implies {\Large \begin{array}{llll} y=\cfrac{1}{13}x+\cfrac{101}{13} \end{array}}\)

The average ticket cost for each concert is given as follows:

The ticket costs are obtained by a system of equations, for which the variables are given as follows:

It cost a total of $1707 to purchase six tickets for concert A and six tickets for concert B, hence:

6a + 6b = 1707

a + b = 284.5.

Three tickets for concert B cost a total of $687, hence the cost for concert B is of:

3b = 687

b = 287/3

b = $95.67.

Replacing into the first equation, the cost for concert A is given as follows;

a = 284.5 - 95.67

a = $188.83.

Answer:

5^125 ways

Step-by-step explanation:

We proceed as follows

Let us label the five printers as A,B,C,D and E

Each printer can print any number of pages since there are no restrictions

Therefore for every page to be printed , there are 5 printer options available

Page 1 = 5 options

Page 2 = 5 options and so on till page 125

So total number of ways to assign 125 pages to five printer = 5*5*5*......*5 (125times)

So total ways = 5^125 ways

Using the Fundamental Counting Theorem, it is found that there are \(5^{125}\) ways for the 125 pages to be assigned to the five printers.

Fundamental counting theorem:

States that if there are n things, each with  ways to be done, each thing independent of the other, the number of ways they can be done is:

\(N = n_1 \times n_2 \times \cdots \times n_n\)

In this problem:

\(N = n_1 \times n_2 \times \cdots \times n_{125}\)

5 is multiplied by itself 125 times, hence:

\(N = 5^{125}\)

There are \(5^{125}\) ways for the 125 pages to be assigned to the five printers.

Two expressions with equal sign is called as equation.

We need to change the sentence "The sum of five times a number and seven is equal to twelve" to equation.

In the equation, times represent multiplication and sum represents addition.

five times a number=5n

The sum of five times a number and seven= 5n+7

The sum of five times a number and seven is equal to twelve=5n+7=12.

The appropriate symbols of inequality are:

a. If x < -3, then 4x < -12.

b. If x > -6, then -2x > 12.

We have,

a.

If x is less than -3, it means that x is a value that is smaller than -3.

To determine the relationship between 4x and -12, we can substitute a value smaller than -3 for x.

Let's take x = -4 as an example.

When x = -4, 4x = 4(-4) = -16.

Since -16 is indeed less than -12, we can conclude that if x < -3, then

4x < -12.

Therefore, the appropriate symbol to complete the statement is <.

b.

In statement b, if x is greater than -6, it means that x is a value that is larger than -6.

To determine the relationship between -2x and 12, we can substitute a value larger than -6 for x.

Let's take x = -5 as an example.

When x = -5, -2x = -2(-5) = 10.

Since 10 is greater than 12, we can conclude that if x > -6, then -2x is not greater than 12.

Therefore, the appropriate symbol to complete the statement is not >, which can be represented as either < or =.

Thus,

The appropriate symbols of inequality are:

a. If x < -3, then 4x < -12.

The length AC in the kite is 8.7 cm.

A kite is a quadrilateral that has two pairs of consecutive equal sides and

perpendicular diagonals. Therefore, let's find the length AC in the kite.

Hence, using Pythagoras's theorem, let's find CE.

Therefore,

7² - 4² = CE²

CE = √49 - 16

CE = √33

CE = √33

Let's find AE as follows:

5²- 4² = AE²

AE = √25 - 16

AE = √9

AE = 3 units

Therefore,

AC = √33 + 3

AC = 5.74456264654 + 3
