Answer:

5(P - 1.00) + 3(P - 0.75)

Step-by-step explanation:

Cost of a package in store A = $P

Discount offered at store A = $1.00

Price paid per package at store A = Cost of a package in store A - Discount offered at store A

= P - 1.00

Cost of a package in store B = $P

Discount offered at store B = $0.75

Price paid per package at store B = Cost of a package in store B - Discount offered at store B

= P - 0.75

Total cost of 5 packages at store A and 3 packages at store B = 5(P - 1.00) + 3(P - 0.75)

Find the area of the surface correct to four decimal places by expressing the area in terms of a single integral and using your

love history [14]

If we substitute $x=r\cos\theta$ and $y=r\sin\theta$ , we get $r^2=x^2+y^2$ , so that

$z=\cos(x^2+y^2)=\cos(r^2)$

which is independent of $\theta$ , which in turn means the surface can be treated like a surface of revolution.

Consider the function $f(t)=\cos(t^2)$ defined over $0\le t\le1$ . Revolve the curve $C$ described by $f(t)$ about the line $t=0$ . The area of the surface obtained in this way is then

$\displaystyle2\pi\int_C\mathrm dS=2\pi\int_0^1\sqrt{1+f'(t)^2}\,\mathrm dt$

$=\displaystyle2\pi\int_0^1\sqrt{1+(-2t\sin(t^2))^2}\,\mathrm dt$

$=\displaystyle2\pi\int_0^1\sqrt{1+4t^2\sin^2(t^2)}\,\mathrm dt\approx7.4144$
