Find the perimeter of a quadrilateral with vertices at C (2, 4), D (1, 1), E (5, 0), and F (3, 4). Round your answer to the nearest hundredth when necessary. 12.76 units 16.25 units 20.12 units 24.85 units

Step-by-step explanation:

Perimeter of the quadrilateral will be the all of all the sides of the quadrilateral.

To get the sides of the quadrilateral, we will use the formula for calculating the distance between two points given as:

D = √(x2-x1)²+(y2-y1)²

For |CD|

C = (2,4), D = (1,1)

|CD| = √(1-2)²+(1-4)²

|CD| = √1²+3²

|CD| = √10

For |DE|

D = (1,1), E = (5,0)

|DE| = √(5-1)²+(0-1)²

|DE| = √4²+1²

|DE| = √17

For |EF|

E = (5,0), F = (3,4)

|EF| = √(3-5)²+(4-0)²

|EF| = √2²+4²

|EF| = √20

For side |CF|

C (2,4) and F(3,4)

|CF| = √(3-2)²+(4-4)²

|CF| = √1²

|CF| = 1

perimeter of the quadrilateral = |CD|+|DE|+|EF|+|CF|

= √10+√17+√20+1

= 12.76units (to nearest hundredth)

Step-by-step explanation:

Took the test

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
