Answer:
the temperature is 10 degrees F at 7 pm, and -2 degrees F at 7 am the next morning. How much did the temperature change between 7 pm and 7 am
Answer:
A. 3 < t < 9
Step-by-step explanation:
When the particle is moving to the right, the velocity is positive.
To find the velocity, take the derivative of s(t) with respect to t.
s(t) = -t³/3 + 13t²/2 − 30t
s'(t) = -t² + 13t − 30
Find when the velocity is 0.
0 = -t² + 13t − 30
0 = t² − 13t + 30
0 = (t − 3) (t − 10)
t = 3, 10
Check the sign of s'(t) in each interval.
0 < t < 3, s'(t) < 0
3 < t < 9, s'(t) > 0
The particle moves to the right when 3 < t < 9.
Simple...there'a a LOT of combinations...
so to simply solve this;there is 5 appetizers, 7 entrees and 3 desserts....
Just take 5*7=35
and
35*3=105
Thu,s there is 105 combinations possible to make.
Thus, your answer, D.
