The number -5 is all of the following except
LenaWriter [7]

The correct answer is A. A whole number

Explanation:

In mathematics, whole numbers include numbers that do not include a fraction, for example, the number 4.2 includes a fraction, and therefore it is not a whole number. Moreover, whole numbers include numbers from 0 to infinity but not negative numbers. This means the number -5 is not a whole number because even then this does not include a fraction it is a negative number. According to this, this number is an integer (it does not include fractions), a rational number (it can be expressed as a fraction), and a real number (it can be represented in a line), but not a whole number.

Find the average value of the function g(x) = <img src="https://tex.z-dn.net/?f=%5Cfrac%7Blnx%7D%7Bx%7D" id="TexFormula1" title=
aleksley [76]

Answer:

\displaystyle  average=\frac{1}{2(e-1)}

Step-by-step explanation:

<u>Average Value of a Function</u>

Given a function g(x), we can compute the average value of g in a given interval (a,b) with the equation:

\displaystyle  average=\frac{1}{b-a}\int_{a}^{b} g(x)dx

We use the given data

\displaystyle  average=\frac{1}{e-1}\int_{1}^{e} \frac{lnx}{x}dx

We now compute the indefinite integral with a u-substitution

\displaystyle  I=\int \frac{lnx}{x}dx

We'll use the substitution u=lnx, du=dx/x. Then

\displaystyle  I=\int u.du

Integrating

\displaystyle I=\frac{u^2}{2}

Since u=lnx

\displaystyle I=\frac{ln^2x}{2}

The average value is

\displaystyle  average=\frac{1}{e-1}\left|\frac{ln^2x}{2} \right|_1^e

\displaystyle  average=\frac{1}{e-1}\left(\frac{ln^2e}{2}-\frac{ln^21}{2} \right )

Since lne=1, and ln1=0

\displaystyle  average=\frac{1}{e-1}\left(\frac{1}{2}-0 \right )

\displaystyle  average=\frac{1}{2(e-1)}

A cookie delivery company charges $0.90 per cookie plus a $3 delivery fee. If an
ss7ja [257]

Answer:

9 cookies

Step-by-step explanation:

The equation is 11.1 = 0.9x + 3. First, we need to isolate the variable so we subtract 3 from both sides. 8.1 = 0.9x. Next we divide both sides by 0.9 which gives us 9 = x or x = 9.
