Answer:
2√2
Step-by-step explanation:
r(t) = (2t, t²)
v(t) = dr/dt
v(t) = (2, 2t)
v(1) = (2, 2)
|v(1)| = √(2² + 2²)
|v(1)| = 2√2
2x+ y = -4 5x + 3y = -6
y= -4 -2x
substitute y=-4-2x into 5x+3y=-6
5x + 3(-4-2x) = -6
5x -12 -6x =-6
-x=6
x=-6
sub x=-6 into 2x+y=-4
-12 + y = -4
y=8
x=-6 and y=8
Answer:
3x +2x-5+(-7x+8)=
-2x+3

7. Incomplete/ Before the race began....
You would set up equations for both the member and the non-member.
The member's equation would be: 384+8x (x being the number of rounds)
The non-member's equation would be: 48x+24x
then you would set them equal to each other and then solve:
384+8x=48x+24x
384=64x
384/64=x
x=6
they would have to play 6 rounds in order to pay the same amount.
