V'(t)=a(t)

deriviive of the velocity is the acceleration

easy peasy
dy/dx v(t)=6t-4
v'(t)=a(t)=6t-4

at=t=3
a(3)=6(3)-4
a(3)=18-4
a(3)=14 ft per second squared

Acceleration is the rate of change of velocity.
So take the derivative of the velocity which would be a =6t-4.  When t=3, a=14 ft/sec^2

Answer:

703.36

Step-by-step explanation:

the formula is v=b×h×pi

pi = 3.14

length: 28

base:8

So base (8) times length (28) times pi (3.14)

8×28×3.14 = 703.36

Jim is selling hot dogs at a ball game. It cost Jim $250 to purchase everything to make the hot dogs. Jim sells hot dogs for $2.
Olegator [25]
So since he is wasting money to purchase everything you won't be gaining but loosing so 250-2h= P bc it's $2 for every hot dog and you are losing again
