The first graph is the answer
Answer:
Step-by-step explanation:
<u>The vertices are:</u>
- K(-12,2), L(-7,12), J(3,-10)
<u>Find the sides using distance formula:</u>
- KL =
≈ 11.18 - LJ =
≈ 24.17 - KJ =
≈ 19.21
<u>Find perimeter:</u>
- P = KL + LJ + KJ
- P = 11.18 + 24.17 + 19.21 = 54.56 units
Step-by-step explanation:
5. Let the equation of the line be y = mx + c
m = (6-15)/(2-(-1)) = -3
sub (2, 6) and m = -3:
6 = -3(2) + c
c = 12
Equation of the line: y = -3x + 12
6. Let the equation of the line be y = mx + c
y-intercept of 7 means c = 7
y = mx + 7
x-intercept: value of x when y = 0
therefore, sub (4, 0):
0 = m(4) + 7
m = -7/4
Equation of the line: y = -7/4x + 7

5 multiplied by (2 multiplied by 2) multiplied by 3 multiplied by 2 = 120
Sorry that I'm writing the word multiplied but I don't have the sign on my keyboard. :D
Answer:
choose B. 54 meters/second, it is closest to my calculation of 55 meters/sec
Step-by-step explanation:
To find average speed between 3 and 8 seconds, find the total distance traveled during that time.
650 meters at 3 seconds
to 375 meters at 8 seconds
then average speed = ( 650 - 375 ) / (8 - 3) = 275 /5 = 55 meters /sec
