How many 5-letter words that have the letter 'x' are possible? Letters may be repeated, and the words don't have to be meaningfu
aliya0001 [1]

Answer:

2115751

Step-by-step explanation:

Solution:

- The number of 5 letter words that contain x is the number of 5 letter words overall minus the number of 5 letter of words without x.

                  How many 5 letter words are there overall?

- The first letter could be one of 26 letters. The same could be said about the second letter, and the third, and the fourth and the fifth .. so on.

- So the number of 5 letter words overall is:

                        26x26x26x26x26 = 26^5 = 11881376

          How many 5 letter words are there that do not contain x?

- The first letter could be one of 25 letters (it could be one of any of the other 25 letters but not x). The second letter could also be one of 25 letters, and so could the third, and so could the fourth, and so could the fifth.

- So the number of 5 letter words that do not contain x is:

                        25x25x25x25x25 = 25^5 = 9765625

- So the number of 5 letter words that contain x is:

                      26^5 - 25^5 = 11881376 - 9765625 = 2115751.

Megan owns a clothing boutique. The table below represents the profit made, in dollars, every year since 2010, where x represent
sergij07 [2.7K]

Answer:C.  Since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line x = 3.


Step-by-step explanation:

Let the profit made by the boutique is given by the function y(x) then

We can see

Profit made in year 2011=profit made in year 2015

i.e.y(1)=y(5)=$84,000

profit made in year 2012=profit made in year 2014

i.e.y(2)=y(4)=$111,000

And profit made in year 2013 is standing in middle as y(3)=$120,000

which gives the line of symmetry x=3.(with reference to the figure)

Therefore, the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line x = 3.

Line of symmetry is an imaginary line that divides a line or shape making two identical halves.

What is the equation in point-slope form of a line that passes through the points (5, −3)(5, −3) and (−2, 9)(−2, 9) ?
Alina [70]
Point sloe is
y-y1=m(x-x1)
slope=m
a ponint is (x1,y1)

slope=(y2-y1)/(x2-x1)
(x,y)
(5,-3)
(-2,9)
slope=(9-(-3))/(-2-5)=12/-7=-12/7
m=-12/7

a point is (5,-3)
x1=5
y=-3
y-(-3)=-12/7(x-5)
y+3=-12/7(x-5)

John bought a used truck for $4,500. He made an agreement with the dealer to put $1,500 down and make payments of $350 for the n
butalik [34]
The price of the truck is 4500 dollars. 
But he paid it into breakdown:
=> 1500 dollars first payment
=> 350 dollars = 10 months => 350 * 10 = 3500 dollars
=> Total = 3500 + 1500 = 5000 dollars
=> 5000 - 4500 = 500 dollars additional for 10 months
=> 500 / 10 = 50 dollars per month
=> 50 * 12 = 600 dollars for 1 year
=> 600 / 4500 = 13.33% of the yearly interest.
