Find the general solution of (x+3)y’=2y

Answers

Answer:

[tex]y=C(x+3)^2[/tex]

Step-by-step explanation:

We are given:

[tex]\displaystyle (x+3)y^\prime=2y[/tex]

Separation of Variables:

[tex]\displaystyle \frac{1}{y}\frac{dy}{dx}=\frac{2}{x+3}[/tex]

So:

[tex]\displaystyle \frac{dy}{y}=\frac{2}{x+3} \, dx[/tex]

Integrate:

[tex]\displaystyle \int\frac{dy}{y}=\int\frac{2}{x+3}\, dx[/tex]

Integrate:

[tex]\displaystyle \ln|y|=2\ln|x+3|+C[/tex]

Raise both sides to e:

[tex]|y|=e^{2\ln|x+3|+C}[/tex]

Simplify:

[tex]|y|=(e^{\ln|x+3|})^2\cdot e^C[/tex]

So:

[tex]|y|=C|x+3|^2[/tex]

Simplify:

[tex]y=\pm C(x+3)^2=C(x+3)^2[/tex]

Megan’s TV had a base price of $189 and the sales tax was 6.88%. Over the next four years, the TV consumed an average of $0.06 of electricity every day. It also needed repairs twice, costing $29 each time. After four years, Megan got a new TV. What was the lifetime cost of Megan’s TV? (Remember that one in every four years is a leap year.)

a.
$357.68
b.
$318.66
c.
$347.66
d.
$351.65

Answers

Answer:

Step-by-step explanation:

price of tv and sales tax = 1.0688×$189 = $202.0032 ≅ $202.00

4 years = 3×365 days + 366 days = 1461 days

cost of electricity = 1461 days × $0.06/day = $87.66

lifetime cost = purchase price + electricity + repairs

= $202.00 + $87.66 + 2·$29

= $347.66

Answer:

347.66 is your answer

What is the average rate of change of the function g(x) = 4 from x = 1 to x = 5? Show your work.​

Answers

9514 1404 393

Answer:

  0

Step-by-step explanation:

The average rate of change of function g on the interval [a, b] is ...

  m = (g(b) -g(a))/(b -a)

For g(x) = 4, the average rate of change on the interval [1, 5] is ...

  m = (g(5) -g(1))/(5 -1) = (4 -4)/(5 -1) = 0/4 = 0

The average rate of change is zero.

__

The function describes a horizontal line, which has a slope of 0 everywhere. Its average rate of change will be 0 on any interval.

Else purchased a prepaid phone card for $15. Long distance calls cost 6 cents a minute using this card. Elsa used her card only once to make a long distance
cal. If the remaining credit on her card is $13.50, how many minutes did her call last?

Answers

Answer:

25 minutes

Step-by-step explanation:

First you subtract the original amount on the card from the remaining amount left.

So you can get the amount of money spent on that call.

$15 - $13.50 = $1.50

Then you divide that number by how much it cost per minute.

$1.50 ÷ 6 = 0.25

Then you get your answer!

Find the unit rate. Enter your answer as a mixed number. A fertilizer covers 5/6 square foot in 1/2 hour

Answers

Answer:

1.67square foot/hr

Step-by-step explanation:

If a fertilizer covers 5/6 square foot in 1/2 hour, then;

5/6 square foot  = 1/2 hour

To determine the unit rate, we will say;

x square foot = 1 hr

Divide both expressions

5/6x = 1/2

5 * 2 = 6x

10 = 6x

x = 10/6

x = 1.67square foot/hr

Hence the unit rate is 1.67square foot/hr
