What at 25 equations that equal 36

1 answer:

7 0

Equations don't equal numbers.

Sometimes their solutions, if they have one, do.

Here are three equations whose solutions are 36 :

x + 15 = 51

x/3 = 12

x² - 72x + 1,296 = 0

Insert three arithmetic means between 4 and 10.

Bumek [7]

Answer:

5.5, 7, 8.5

Step-by-step explanation:

Find the mean of 4 and 10, that is

$\frac{4+10}{2}$ = $\frac{14}{2}$ = 7

Now repeat with 4 and 7 and 7 and 10

$\frac{4+7}{2}$ = $\frac{11}{2}$ = 5.5

$\frac{7+10}{2}$ = $\frac{17}{2}$ = 8.5

Hence

4, 5.5, 7, 8.5, 10 ← is an arithmetic sequence with d = 1.5

Determine whether the given differential equation is Exact or not exact. If it is exact, solve it directly. If it not exact, sol

MatroZZZ [7]

Answer:

lets take a differential equation

$xy^3dx+(x^2y^2+1)dy=0\\let\\M= xy^3\\and\\N=(x^2y^2+1)$

taking derivative of M w.r.t y and N w.r.t x

$dM/dy=3xy^2\\dN/dx=2xy^2\\so\\dM/dy\neq dN/dx$

so this is an in exact equation we will find integrating factor and make it exact equation

$U=e^\int\limits^_{(-dN/dx-dM/dy)} \,/ M\\\\=e^\int\limits^ {2xy^2-3xy^2} \, /xy^3\\=e^\int\limits^ {-xy^2} /xy^3\\=e^\int\limits^{-1/y} \\=e^-^l^n^y\\=1/y$
