Which equation can be used to represent six added to twice the sum of a numbee and four is equal to one half of the difference o

Ronch [10]

Answer: $6 + 2 (x+4)$ = $\frac{3}{2}$ $(3-x)$

Step-by-step explanation:

let the number be x , then :

six added to twice the sum of a number and four means :

$6 + 2 (x+4)$

one half of the difference of three and the number means :

$\frac{3}{2}$ $(3-x)$

combining the two , we have

$6 + 2 (x+4)$ = $\frac{3}{2}$ $(3-x)$

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

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