Any help with this greatly appreciated.
Anestetic [448]

Put the equation in standard linear form.

x'(t) + \dfrac{x(t)}{t + 5} = 5e^{5t}

Find the integrating factor.

\mu = \exp\left(\displaystyle \int \frac{dt}{t+5}\right) = e^{\ln|t+5|} = t+5

Multiply both sides by \mu.

(t+5) x'(t) + x(t) = 5(t+5)e^{5t}

Now the left side the derivative of a product,

\bigg((t+5) x(t)\bigg)' = 5(t+5)e^{5t}

Integrate both sides.

(t+5) x(t) = \displaystyle 5 \int (t+5) e^{5t} \, dt

On the right side, integrate by parts.

(t+5) x(t) = \dfrac15 (5t+24) e^{5t} + C

Solve for x(t).

\boxed{x(t) = \dfrac{5t+24}{5t+25} e^{5t} + \dfrac C{t+5}}

How to simplify 20/10
Andreyy89

In order to get the answer to this question you will have to find the common factor and then divide the numerator and denominator by the common factor to get the answer.

\frac{20}{10}

CF=10

20\div10=2

10\div10=1

\frac{2}{1} =2

= \frac{2}{1} or2

Therefore the answer is "2."

Hope this helps.

15 1/4 acres of land are to be divided into lots of at least 2/3 acres each What is the maximum number of lots that can be creat
Sholpan [36]
Well, if you want the maximum number of splits, then you want to make
each individual split as small as possible. 
That's 2/3 acre.  How many will that give you ?

                  (15 and 1/4) divided by (2/3)

             =      (15.25)  /  (0.666...)  =  22.875 pieces .

The maximum number of 2/3-acre lots you can sell is 22 lots.

Then you have 58.3% of an acre of land left over that you can't sell
because it's less than 2/3 acre.  Sadly, that 58.3% of an acre is just
about the size of the lot that I've been living n for almost 30 years. 
You really know how to rub it in, dontcha !

1.<br> Write a polynomial function in factored form with zeros at -2, 5, and 6.
Hatshy [7]

Answer:

f(x) = (x + 2) (x − 5) (x − 6)

Step-by-step explanation:

f(x) = (x − (-2)) (x − 5) (x − 6)

f(x) = (x + 2) (x − 5) (x − 6)

How can you decompose the composite figure to determine its area?
Anna007 [38]

For this case the first thing you should do is observe that the diameter of the four semicircles is the same.

Therefore, we can decompose the figure as follows:


1) We draw the diameters of the four semicircles to form a square.


2) We divide the figure into a square and four semicircles


3) The total area is the sum of the area of the square, plus the area of the 4 semicircles.


Answer:

c)as a square and four semicircles
