answer

8/25

Step-by-step explanation:

so you would keep the first fraction (2/15) then you would change the symbol then you would flip the other fraction (5/12). then you would multiply 2*12=24 and 15*5=75. then you would simplifie it. it would be 8/25.

Titiknya 10 dan 8<br> ∫x-8)( x-9) (x-10) dx

Sav [38]

$\displaystyle\int_8^{10}(x-8)(x-9)(x-10)\,\mathrm dx$

Consider the substitution,

$y=x-9\implies\begin{cases}y-1=x-10\\y+1=x-8\\\mathrm dy=\mathrm dx\end{cases}$

so that the integral is equivalent to

$\displaystyle\int_{-1}^1y(y+1)(y-1)\,\mathrm dy$

Notice that

$f(y)=y(y+1)(y-1)\implies f(-y)=-y(-y+1)(-y-1)=-y(y-1)(y+1)=-f(y)$

which means $f(y)$ is odd, so

$\implies\displaystyle\int_{-1}^1f(y)\,\mathrm dy=0$

Perhaps more work than necessary, but it does make it easier to see that the original integrand exhibits some symmetry about $x=9$ .

What’s the area of the shape

maxonik [38]

Answer:

19.63

Step-by-step explanation:

To find the area of a circle you can use the formula πr². The diameter (10) is twice the radius. So, the radius is 5. 5² = 25. 25x π =25π. Then you must divide by 4 because the shape is 1/4 a circle.

Hope this helps ;)
