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.
Answer:
90 dancers
Step-by-step explanation:
150/5=30
30x3=90
Answer:
9) p = 48
10) a = 3.6
Step-by-step explanation:
9) p/8 + 3 = 9
p/8 = 6
p = 48
10) 12a/4 + 18/3 = 20.4
4a + 6 = 20.4
4a = 14.4
a = 3.6
