Let they be x.

Cost of textbooks + laptops cant greater than total amount.

(cost of 1 textbooks * number of textbooks) + (cost of 1 laptop * number of laptops ≤ 6500

(30*116) + (x*439) ≤ 6500

3480 + 439x ≤ 6500

439x ≤ 3020

x ≤ 6.8(approx)

Last natural number is 6, says, they can buy 6 laptops at max.

Evaluate integral_S integral (x - 2y + z) dS. S: z = 16, x^2 + y^2 le 1

vovikov84 [41]

$S$ is the disk of radius 1 parallel to the $x,y$ -plane and lying in the plane $z=16$ . Parameterize this surface by

$\vec r(u,v)=u\cos v\,\vec\imath+u\sin v\,\vec\jmath+16\,\vec k$

with $0\le u\le1$ and $0\le v\le2\pi$ . Take the normal vector to $S$ to be

$\vec r_u\times\vec r_v=u\,\vec k$

(the orientation doesn't matter because this is a scalar surface integral)

Then

$\displaystyle\iint_S(x-2y+z)\,\mathrm dS=\iint_S(u\cos v-2u\sin v+16)\|u\,\vec k\|\,\mathrm du\,\mathrm dv$

$=\displaystyle\int_0^{2\pi}\int_0^1(u^2(\cos v-2\sin v)+16u)\,\mathrm du\,\mathrm dv=\boxed{16\pi}$

Anastasy [175]

Answer:

- 46

Step-by-step explanation:

evaluate g(- 2) then substitute the result into f(x) , that is

g(- 2) = (- 2)² + 5 = 4 + 5 = 9 , then

f(9) = - 5(9) - 1 = - 45 - 1 = - 46
