Furkat [3]

Answer:

a) 676, 1296

b) 17576, 46656

c) 456976, 1679616

Step-by-step explanation:

firstly we know that there are 26 letters in the alphabet.

there are 26 ways of choosing the first character and 26 ways choosing the second character,

Therefore, the possible number of domains with two leeter is;

n = 26²

= 26 × 26

= 676

now when the digits are allowed, there are 26 + 10 = 36 characters to be used in total

therefore the possible number of domains with two characters is;

n = 36²

= 36 × 36

= 1296

b)

there are 26 ways of choosing each character

therefore, the possible number of domains with three letters is

n = 26³

= 26 × 26 × 26

= 17576

when the digits are allowed, there are 26 + 10 = 36 characters to be used in total

therefore , the possible number of domains with three characters is;

n = 36³

= 36 × 36 × 36

= 46656

c)

there are 26 ways of choosing each character, therefore the possible number of domains with four letters is;

n = 26⁴

n = 26 × 26 × 26 × 26

n = 456976

when the digits are allowed, there are 26 + 10 = 36 characters to be used in total

therefore, the possible number of domains with four characters is;

n = 36⁴

n = 36 × 36 × 36 × 36

= 1679616

Which of the following is NOT true of a perpendicular bisector?
kodGreya [7K]

To construct a perpendicular bisector, we have to draw two arcs using each of the endpoints as centers

<h3>What is a perpendicular bisector?</h3>

A perpendicular bisector is said to be a line that intersects the segment of another line perpendicularly and also divides it into two equal parts.

The properties of a perpendicular bisector include:

  • It divides a line segment into two equal parts
  • It makes right angles with the line segment.
  • Points in the perpendicular bisector are equal from the line of the segment.

Hence, all the mentioned properties are correct except that to construct it, we have to draw two arcs using each of the endpoints as centers.

leva [86]

Answer:

0.25D^2 π in^2.

Step-by-step explanation:

The cross section is a circle of diameter D inches, so its radius is 0.5D inches.

The area of cross section is  πr^2

= (0.5D)^2 π

= 0.25D^2 π in^2.

PLEASE HELP ASAPPPP!!!!!!!!
Lisa [10]

Answer:

slope: 1.25

Part B: The order in which the points are given does not change the value of the slope

Step-by-step explanation:

Part A. Given two points we can find slope using the slope formula

m = \frac{y_2-y_1}{x_2-x_1}

Given the points ( -6, 1/2) and ( -4,3 )

We plug in the y values and x values (starting with the last point give )

m=\frac{3-.5}{-4-(-6)} \\3-\frac{1}{2} =2.5\\-4-(-6)=2\\\frac{2.5}{2} =1.25\\

so we can conclude that the slope of a line that passes through the points ( -6, 1/2) and ( -4,3 ) is 1.25

Part B. The order in which the points are given does not change the value of the slope

Observe -

* flip the order in which the points are given *

given (-4,3) and (-6,1/2)

we use the same formula

*plug in the y and x values starting with the last point*

m=\frac{.5-3}{-6-(-4)} \\.5 - 3=-2.5\\-6-(-4)=-2\\\frac{-2.5}{-2} =1.25

The slope still equals 1.25 meaning that the order in which the points are given does not matter.
