Answer:
Answer:
a = - 1.1
Step-by-step explanation:
Condition for a single variable function f(x) to be decreasing is f'(x) < 0.
So, in our case, .
Then, differentiating with respect to x on both sides we get,
⇒
⇒
{Dividing both sides with - 1 and hence the inequality sign changes}
⇒
⇒ 8 > - 6x³ {Multiplying both sides with x³}
⇒ 6x³ > - 8 {Interchanging the sides}
⇒
⇒ x > - 1.1
Therefore, a = - 1.1. (Answer)

Answer:
25 Months
Step-by-step explanation:
Let's make the equations first,
Plan A: 70x Plan B: 50x+500...
Now we make it into an equivalent equation:
70x=50x+500...
Then we solve:
70x=50x+500-50x -50x20x=500...
÷20 ÷20x=25...
To check if it's correct, we just plug it in:
70(25)=50(25)+500...
1750=1750...
