storchak [24]

Answer:

3.7001 × 10 to the power of 4 is the answer for #1

aalyn [17]
For every 3 girls, there are 4 boys. if there are nine girls, that expands to three extra boys, because for every three theres an extra one. so there are 12 boys (9+3.) the final ratio, boys to girls, is 12:9.

If C is the line segment from 7 3 to 0 0 find the value of the line integral C 4y2i xj dr
saul85 [17]
Parameterize C by

\mathbf r(t)=(x(t),y(t))=(1-t)(7,3)+t(0,0)=(7-7t,3-3t)

where 0\le t\le1. Then

\mathrm d\mathbf r=(-7\,\mathbf i-3\,\mathbf j)\,\mathrm dt

and the line integral is equivalent to

\displaystyle\int_C(4y^2\,\mathbf i+x\,\mathbf j)\cdot\mathrm d\mathbf r=\int_0^1(4(3-3t)^2\,\mathbf i+(7-7t)\,\mathbf j)\cdot(-7\,\mathbf i-3\,\mathbf j)\,\mathrm dt
\displaystyle=\int_0^1(-252t^2+525t-273)\,\mathrm dt=-\dfrac{189}2
