PLS HELP ME d + 7 2d-5 10d+ 1 Write and simplify an expression

tester [92]

answer: D = 1

Isolate the variable by dividing each side by factors that don't contain the variable. 7 (2d - 1) + 5 (2 - 3d) = 2d

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

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