Answer:

3\sqrt{2}

Step-by-step explanation:

We need to find the absolute value of the complex number -4 -√2i

to find absolute value of any complex number we use formula

|a+bi| = \sqrt{a^2+b^2}

-4 -√2i , here a=-4  and b=-sqrt(2)

|-4-\sqrt{2}i|} =\sqrt{(-4)^2+(-\sqrt{2})^2}

= \sqrt{16+2}

= \sqrt{18}

=  3\sqrt{2}

The perimeter of a stop sign has a perimeter of 16x2 - 80x. What is the length of one side?
uranmaximum [27]
Since a stop sign is an octagon it has eight sides.  So the perimeter will be:

p=8x,  p=perimeter and x=side length.  We are told that the perimeter is equal to:

16x^2-80x so we can say:

16x^2-80x=8x subtract 8x from both sides

16x^2-88x=0  factor out 8x

8x(2x-11), since we know x>0

x=11/2

x=5.5 units

A grocer bought n eggs at $x each. He marked up the price of each egg by $y and sold all of them. Find the sales amount, express
Alex777 [14]

Answer:

Sales = n \times ($x + $y)

Step-by-step explanation:

The basic simple sales equation is

Quantity \times Price = Sales

Here in the given question,

Total quantity of sales = n

Price = Cost + markup

(Markup refers to the profit added to cost)

Thus price = $x (cost) + $y (markup)

Sales = n \times ($x + $y)

Sales amount is the total amount received from sales of products, total quantity at some price provided.

expeople1 [14]
F(x)=5/x
g(x)=2(x^2)+5x
f(x) has a domain of all real numbers excluding zero
g(x) has a domain of all real numbers
fog(x)=5/(2(x^2)+5x)
fog(x)=5/(x(2x+5))
fog(x) has a domain that excludes both zero and -5/2
