yulyashka [42]

Let G be the granola we need (in pound)

Let N be the nut we need (in pound)

Trail mix cost $5.00 per pound---> cost for 7 pound = 5 x 7 = $ 35

4.5G+7N= 35

G+ N = 7

Therefore G = 5.6 N=1.4, we would need 5.6 pound granola & 1.4 pound nut

18/X=2.4/28 find X plz help
yulyashka [42]
Cross multiply

18 / X = 2.4 / 28
so
18 * 28 = X (2.4)
and that becomes
504 = X * 2.4
then divide by 2.4
X = 210

SOLVE. integration of (1-v) /(1+v^2)
Nutka1998 [239]
\displaystyle\int\frac{1-v}{1+v^2}\,\mathrm dv=\int\frac{\mathrm dv}{1+v^2}-\int\frac v{1+v^2}\,\mathrm dv

The first integral is already standard and has an antiderivative in terms of \arctan v. For the second integral, take w=1+v^2 so that \dfrac{\mathrm dw}2=v\,\mathrm dv. Then

\displaystyle\int\frac{\mathrm dv}{1+v^2}-\int\frac v{1+v^2}\,\mathrm dv=\arctan v-\frac12\int\frac{\mathrm dw}w
=\arctan v-\dfrac12\ln|w|+C
=\arctan v-\dfrac12\ln(1+v^2)+C
