A mom buys a jersey and a water bottle for each of the ten players on the dodgeball team. Each water bottle cost $11.60. The mom

spends a total of $464 For jerseys and water bottles.
Enter an equation that models the situation with u, the cost of one jersey?

464 = 10w + 10u

464 = 10(11.60) + 10u

464 = 116 + 10u

384 = 10u

38.4 per jersey

Evaluate the surface integral. s (x + y + z) ds, s is the parallelogram with parametric equations x = u + v, y = u − v, z = 1 +

Stolb23 [73]

$S$ is given to be parameterized by

$\mathbf r(u,v)=\langle x(u,v),y(u,v),z(u,v)\rangle=\langle u+v,u-v,1+2u+v\rangle$

with $0\le u\le3$ and $0\le v\le2$ . We have

$\mathbf r_u=\langle1,1,2\rangle$
$\mathbf r_v=\langle1,-1,1\rangle$
$\mathbf r_u\times\mathbf r_v=\langle3,1,-2\rangle$
$\left\|\mathbf r_u\times\mathbf r_v\right\|=\sqrt{14}$

The surface integral is then

$\displaystyle\iint_S(x+y+z)\,\mathrm dS=\iint_S(x(u,v)+y(u,v)+z(u,v))\left\|\mathbf r_u\times\mathbf r_v\right\|\,\mathrm du\,\mathrm dv$
$=\displaystyle\sqrt{14}\int_{u=0}^{u=3}\int_{v=0}^{v=2}((u+v)+(u-v)+(1+2u+v))\,\mathrm dv\,\mathrm du$
$=\displaystyle\sqrt{14}\int_{u=0}^{u=3}\int_{v=0}^{v=2}(4u+v+1)\,\mathrm dv\,\mathrm du$
$=\displaystyle\sqrt{14}\left(8\int_{u=0}^{u=3}u\,\mathrm du+3\int_{v=0}^{v=2}v\,\mathrm dv+6\right)$
$=\displaystyle\sqrt{14}\left(8\int_{u=0}^{u=3}u\,\mathrm du+3\int_{v=0}^{v=2}v\,\mathrm dv+6\right)$
$=48\sqrt{14}$

Calcola l'area di un rombo sapendo che il perimetro è 160 cm è la sua altezza misura 38,4 cm

AURORKA [14]

Answer:

41,6 cm

Step-by-step explanation:

Formula for Perimeter of a rhombus: P = 2L + 2H (H is the height, L the length)

Perimeter: 160 cm = 2L + 2(38,4 cm), or

160 cm + 76.8 cm + 2L, or

83.2 cm = 2L

and so the height (altezza) is H = 83.2 cm / 2 = 41,6 cm

4x + 2y = 4<br> Is y a function of x?

Lisa [10]

Yes y is a function of x.

Rewrite the function using algebra to get this:

y = -x + 2

That forms an equation of a line whose slope is -2 and whose y-intercept is 2
