I know the correct answers but I need you to answer my math questions first
It would be -(-31) because a negative and negative is a positive
Answer:
3.2 gallons
Step-by-step explanation:
2640 / 825 = 3.2
Answer:
21 bushels of sweet corm weight 735 pounds.
Step-by-step explanation:
Given:
Weight of 21 bushels of sweet corn is obtained by multiplying the unit weight to the number of bushels required.
Unit weight of sweet corn is the weight of 1 bushel of sweet corn.
Weight of 1 bushel of sweet corn = 35 pounds
So, weight of 21 bushels of sweet corns = 
pounds.
Therefore, 21 bushels of sweet corn weigh 735 pounds.
<span>the particle's initial position is at t=0, x = 0 - 0 + 4 = 4m
velocity is rate of change of displacement = dx/dt = d(t^3 - 9t^2 +4)/dt
= 3t^2 - 18t
acceleration is rate of change of velocity = d(3t^2 -18t)/dt
= 6t - 18
</span><span>the particle is stationary when velocity = 0, so 3t^2 - 18t =0
</span>3t*(t - 6) = 0
t = 0 or t = 6s
acceleration = 6t - 18 = 0
t = 3s
at t = 3s, velocity = 3(3^2) -18*3 = -27m/s
displacement = 3^3 - 9*3^2 +4 = -50m
