Eli read four more biographies than historical fiction book during the semester. He also read two fewer mysteries than historica

9966 [12]

Answer: Eli read 3 historical fiction books , 7 biographies and 1 mystery book.

Step-by-step explanation:

Let x be the number of historical fiction books Eli read.

Then, Number of biographies he read = x+4

Number of mysteries he read = x-2

If he read a total of eleven books during the semester , then we have the following equation :

$x+x+4+x-2=11$

$\\\\\Rightarrow\ 3x+2=11$

$\\\\\Rightarrow\ 3x=9$ (Subtract 2 from both sides )

$x=3$ (Divide both sides by 3)

Therefore , Number of historical fiction books Eli read = 3

Number of biographies he read = 3+4=7

Number of mysteries he read =3-2=1

Hence, Eli read 3 historical fiction books , 7 biographies and 1 mystery book.

Evaluate the surface integral S F · dS for the given vector field F and the oriented surface S. In other words, find the flux of

zubka84 [21]

V is the 3D region enclosed by S.

div(F)= ∂(x)/∂x + ∂(y)/∂y + ∂(10)/∂z = 2

∫ = ∫∫∫ [V] div(F) dV = 2 ∫∫∫ [V] dV

Using cylindrical coords, ( rcos(θ), y, rsin(θ) ), dV=rdrdθdy

∫ = 2 ∫∫∫ rdrdθdy, [r=0,1], [θ=0,2π], [y=0,7−rcos(θ)] = 14π (easily integrated)
