Janie receives an allowance of $3 per week. In addition, she can earn $2 for each chore she does. This week, she wants to earn e

olasank [31]

Hi there! The answer is 5.

As you mentioned in the question, the amount of chores Janie does is represented by c.

When we know this we can set up an expression which represents the total amount of money Janie earns.

She always receives $3.

She also receives
$2 × the amount of chores
$2 × c = 2c

The expression which represents Janie's total earnings is 3 + 2c.

Now we can start solving.
$3 + 2c = 13$

Subtract 3 from both sides.
$2c = 10$

Divide both sides by 2.
$c = \frac{10}{2} = 5$

Hence, Janie must do 5 chores to earn enough money to buy a CD.

use the differential equation given by dy/dx=xy/3, y > 0. Find the particular solution y = f(x) to the given differential equ

Ahat [919]

<span>dy/dx=xy/3, y > 0 can be rewritten in terms of only one variable (x or y) each:

3 dy
----- = x*dx (first term is all in y; second term all in x).
y
x^2
Integrating, 3 ln y = ------- + ln C, Then ln y^3 = (1/2)x^2 + ln C.
2

Combining the log terms:

ln y^3-ln C = (1/2)x^2.

Given: if x=0, y=4. Subst. these v alues into the equation in y given above:
4^3
ln 4^3 - ln C = (1/2)(0)^2 = 0. Then ln ------- = 0, which tells us that
C

4^3 = C. Thus, the solution is </span>ln y^3 = (1/2)x^2 + ln (4/3).

There are other ways in which you could write this same expression. You could, for example, solve for either y^3 or y alone.
