What times what equals 234, but then if you add them you get 31

1 answer:

6 0

13*18
x*y =234
x+y=31

we know the 2 # have to be double digits and both between 10-20

find 2 values that * to a number that ends in 4. Those are the ones value

1*4 11 and 14
2*2 12 and 12
3*8 13 and 18

only 13 and 18 add up to 31 and multiply to 234

The area of the region in the first quadrant between the graph of y = k*sin(x) and x-axis (where k > 0 ) on the closed interv

astraxan [27]

Note that $0\le k\sin x\le k$ in the given closed interval, so the area is exactly given by the definite integral

$\displaystyle\int_0^\pi k\sin x\,\mathrm dx$

(no absolute values needed!)

Integrating gives

$-k\cos x\bigg|_{x=0}^{x=\pi}=-k(\cos\pi-\cos0)=-k(-1-1)=2k$
