Best is to draw a sketch of the three points.
Next step is to find the distances BC, CD, DB.
The perimeter is the sum of the three distances.
The distances are found using the distance formula:
D=sqrt((y2-y1)^2+(x2-x1)^2)
order of (x1,y1), (x2,y2) is not important.
BC=sqrt((3- -3)^2+(5-3)^2)=sqrt(6^2+2^2)=sqrt(40)=5.324
CD=sqrt((-1-3)^2+(0-5)^2)=sqrt(4^2+5^2)=sqrt(41)=6.403
DB=sqrt((-3- -1)^2+(3-0)^2)=sqrt(2^2+3^2)=sqrt(13)=3.606
So perimeter = BC+CD+DB=16.333 (approximately)
Answer:
7.854
Step-by-step explanation:
Answer:
651,641 more people live in Nashville.
Step-by-step explanation:
Since more people live in Nashville, we subtract the population of Nashville by the population of Spring Hill to get:
691,243 - 39,602
= 651,641
Answer:
Step-by-step explanation:
Let the numbers be x and y
<u>Three times the first number minus two times the second number equals -7:</u>
<u>The second number equals one less than negative three times the first number:</u>
<u>Substitute y in the first equation and solve for x:</u>
- 3x - 2(-3x - 1) = -7
- 3x + 6x + 2 = -7
- 9x = -9
- x = -1
<u>Find the value of y:</u>
- y = -3(-1) - 1
- y = 3 - 1
- y = 2
The numbers are -1 and 2
