For this case we have the following function:
f (t) = -16t2 + 32t + 384
By definition we have to:
The average rate of change:
AVR = (f (t2) - f (t1)) / (t2 - t1)
Where,
For t1 = 4
f (4) = -16 * (4) ^ 2 + 32 * (4) + 384
f (4) = 256
For t2 = 6
f (6) = -16 * (6) ^ 2 + 32 * (6) + 384
f (6) = 0
Substituting values we have:
AVR = (0 - 256) / (6 - 4)
AVR = -128
Answer:
The average rate of change of f (t) from t = 4 seconds to t = 6 seconds is -128 feet per second.
The factors of 30 are 1,2,3,5,6,10,15,30
we notice that 3+6=9
Answer:
Step-by-step explanation:
3(x +6 ) = -18
Divide both sides by 3
3(x+6)/3= -18/3
x +6 = - 6
Subtract 6 from both sides
x + 6 - 6 = - 6 - 6
x = - 12
Whats the question? there should be more to it.
