Answer:
A: 
Step-by-step explanation:
Acceleration is second derivative of position, velocity is first derivative. Therefore, the velocity is the integral of acceleration.
Integrate:
V(0)=-5:
Therefore, v(t):
not sure but you should use jiskha or photo math. hope this helps
Answer:
1.8 Kg
Step-by-step explanation:
a week- 3kg rice
every day-0.6 kg rice
therefore, multiply 3 kg by 0.6kg
3kg x 0.6kg =1.8 kg
he will have 1.8 kg rice after 4 days
have a great day !
You did not provide us with equations to select.
Find the slope m.
m = (1 - 2)/(3 - (-1))
m = -1/(3 + 1)
m = -1/4
Use the slope and one of the points and plug into the point-slope formula.
y - 1 = (-1/4)(x - 3)
Isolate y.
y - 1 = (-1/4)x + (3/4)
y = (-1/4)x + (3/4) + 1
y = (-1/4)x + (7/4)
