(-5x^5)(a) = 25x^7 + 100x^5
<u>+5x^5 +5x^5</u>
a = 25x^7
The answer would be 13/15

Answer:
1/2 or 50% of the population has heard the rumor when it is spreading fastest.
Step-by-step explanation:
We need to take the derivative with respect to y from the r(y) = dy/dt = 2y(1-y) and equal to zero. At this condition we maximize the function and will get the maximum of the rumor spreading.

Therefore we just need to find y:

So 1/2 or 50% of the population has heard the rumor when it is spreading fastest.

Answer:
x = 6
Step-by-step explanation:
The equation to solve is:

We can convert it to exponential form and find the answer. Below we show log to exponential form formula:

Now, we convert the log to exponential:

We now solve for "x",

We know the base number of log cannot be negative, so we disregard x = -6 and take x = 6 as our answer
