Answer:

$\huge f( - 9) = 1$

Step-by-step explanation:

$f(x) = \frac{x}{3} + 4 \\$

To find f(-9) , substitute the value of x that's - 9 into f(x) , that's for every x in f(x) replace it with - 9

We have

$f( - 9) = - \frac{9}{3} + 4 \\ = - 3 +4$

We have the final answer as

$f( - 9) = 1$

Hope this helps you

The Excel file Store and Regional Sales Database provides sales data for computers and peripherals showing the store identificat

zhannawk [14.2K]

Answer:

Total sales revenue use excel function : ( SUMIF. =sumif(range, criteria, [sum_range] )

For each of the stores: Use excel function: For Store 1: =sumif(B4:B99,1,I4:I99) then repeat same for Store 2 to store 8

Step-by-step explanation:

To modify the spreadsheet to calculate the total sales revenue we will add a column " sales revenue "

multiply values of column : ( unit sold * unit price ) to get Total sales revenue. then use excel function : ( SUMIF. =sumif(range, criteria, [sum_range] ) to find Total sales revenue

calculate the total revenue for each of the 8 stores using a pivot table using "store identification number" in row and " sales revenue " in values field

To get the sales revenue ; replace " store identification value" with sales region " column

Which answer is equivalent to<br> ??? Help please

grigory [225]

Answer:

$\large\boxed{\dfrac{36}{25}}$

Step-by-step explanation:

$\text{Use}\ a^{-n}=\dfrac{1}{a^n}\\\\\dfrac{5^{-2}\cdot9}{2^4\cdot4^{-3}}=(5^{-2}\cdot9):(2^4\cdot4^{-3})=\left(\dfrac{1}{5^2}\cdot9\right):\left(2^4\cdot(2^2)^{-3}\right)\\\\\text{use}\ (a^n)^m=a^{nm}\\\\=\left(\dfrac{1}{25}\cdot9\right):(2^4\cdot2^{-6})\\\\\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=\dfrac{9}{25}:2^{4+(-6)}=\dfrac{9}{25}:2^{-2}=\dfrac{9}{25}:\dfrac{1}{2^2}=\dfrac{9}{25}:\dfrac{1}{4}=\dfrac{9}{25}\cdot\dfrac{4}{1}=\dfrac{36}{25}$

50 Is a(n) ________of 10 because 5×10 = 50

Svet_ta [14]

Answer:

50 Is a multiple of 10 because 5×10 = 50

Step-by-step explanation:

We want to fill in the gap in :

50 Is a(n) ________of 10 because 5×10 = 50

Recall that multiples of a number are obtained by multiplying the number by natural counting numbers.

In this case one multiple of 10 is 50.

The reason is that, we obtain 50 by multiplying 5 by 10 to get;

$5 \times 10 = 50$

Therefore the best complete is multiple.

Use the Rational Zeros Theorem to write a list of all possible rational zeros of the function.f(x) = 3x3 + 39x2 + 39x + 27

kramer

First, we can factor this to make it easier to solve:

3(x^3 + 13x^2 + 13x + 9)

Now, we can use the rational root theorem like so:

List factors of 9:

1, 3, 9.

List factors of 1:

Because of this, we know our possible rational roots are:

+/-1, +/-3, +/-9

If none of these zeros fit using the remainder theorem, then we know our roots will be irrational.
