Multiply 9 books by 55% by doing

9 x .55 = 4.95

We can't have 4.95 books, though so it rounds down to 4 because you can't just add another .05.

The percent decrease in the music revenue is 60.2%

<h3>How to calculate the percent decrease ?</h3>

Percent decrease can be described as the reduction in the value of a number.

In 1999, the revenue of the company was $14.1 billion

In 2014, the revenue of the company was $5.6 billion

The percent decrease can be calculated as follows

= 14.1 - 5.6/14.1 × 100

= 8.5/14.1 × 100

= 0.602 × 100

= 60.2 %

Hence the percent decrease is 60.2%

A one-parameter family of solutions of the de p' = p(1 − p) is given below.

Answer:

A solution curve pass through the point (0,4) when $c_{1} = -\frac{4}{3}$ .

There is not a solution curve passing through the point(0,1).

Step-by-step explanation:

We have the following solution:

$P(t) = \frac{c_{1}e^{t}}{1 + c_{1}e^{t}}$

Does any solution curve pass through the point (0, 4)?

We have to see if P = 4 when t = 0.

$P(t) = \frac{c_{1}e^{t}}{1 + c_{1}e^{t}}$

$4 = \frac{c_{1}}{1 + c_{1}}$

$4 + 4c_{1} = c_{1}$

$c_{1} = -\frac{4}{3}$

A solution curve pass through the point (0,4) when $c_{1} = -\frac{4}{3}$ .

Through the point (0, 1)?

Same thing as above

$P(t) = \frac{c_{1}e^{t}}{1 + c_{1}e^{t}}$

$1 = \frac{c_{1}}{1 + c_{1}}$

$1 + c_{1} = c_{1}$

$0c_{1} = 1$

No solution.

So there is not a solution curve passing through the point(0,1).
