Distance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(-5,8)(10,-7)
d = sqrt (10 - (-5)^2 + (-7 - 8)^2
d = sqrt (10 + 5)^2 + (- 15^2)
d = sqrt (15^2) + (-15^2)
d = sqrt 225 + 225
d = sqrt 450
d = 21.21
Answer:
3/2
Step-by-step explanation:
Let it be
C (5;4) , A (2;1) ; B(7;6)
Suppose that C divide the line AB in ratio m/n from point A (AC is m, CB is n)
Use the formula xc=(m*xb+n*xa)/ (m+n)
5=(m*7+2n)/(m+n)
5m+5n= 7m+2n
2m=3n
m/n=3/2
Answer:
4 songs: $3.96 8 songs: $7.92
Step-by-step explanation:
- Divide to find out how much it costs for 1 song.
5.94 / 6 = 0.99 <u>Each song costs $0.99</u>
- Now multiply $0.99 by (number of songs)
- 0.99 x 4 = 3.96
- 0.99 x 8 = 7.92
