ANSWER
EXPLANATION
The given logarithmic expression is:
Recall and use the product rule of logarithm
We apply this rule to obtain,
We multiply out the argument to get;
The correct answer is
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.
Answer:
It is undefined
Step-by-step explanation:
Answer:
Black is 3.57%
Green is 96.43%
Step-by-step explanation:
Since 27 green than black
Let the black car be b
So green cars which 27 more than black means 27b
So to calculate the percentage of green we will have
27b/27b+b ×100
27b/28b ×100
Let's eliminate the b
27/28×100
2700/28
96.43%
So let's calculate for Black
b/27b+b ×100
b/28b ×100
Eliminate b
1/28 ×100
100/28
3.57%
Therefore the percentage for Black is 3.57% and for green is 96.43%
