Answer:

Step-by-step explanation:

2y + 100 +6x-10=180(in a cyclic quadrilateral opposite angles are supplementary)

2y+6x+90 =180

2y + 6x = 90

dividing each side by 2

y+3x = 45 ........1

7x+1+2y+74 =180 ( same reason)

7x + 2y =105 ............2

multiplying 1 by 2

2y +6x =90........ 3

subtracting 3 from 2

7x+2y-2y-6x = 105-90

x = 15

substituting x=15 in 1

y+45 =45

y= 0

please mark me as the brainliest

Evaluate the integral using integration by parts with the indicated choices of u and dv. (Use C for the constant of integration.

Aleksandr-060686 [28]

Take

$u=\ln x\implies\mathrm du=\dfrac{\mathrm dx}x$

$\mathrm dv=4x^2\,\mathrm dx\implies v=\dfrac43x^3$

Then

$\displaystyle\int4x^2\ln x\,\mathrm dx=\frac43x^3\ln x-\frac43\int x^2\,\mathrm dx=\frac43x^3\ln x-\frac49x^3+C$

$=\boxed{\dfrac49x^3(3\ln x-1)+C}$
