Answer:

10, 12, 14

Step-by-step explanation:

x-2, x, x+2

3x = 2 x ((x - 2) + (x + 2)) -12

3x = 4x - 12

x = 12

x-2 = 10

x+2 = 14

check: (10 + 14) x 2 - 12 = 48 - 12 = 36 = 3 x 12

The Better Baby Buggy Co. has just come out with a new model, the Turbo. The market research department predicts that the demand
andreyandreev [35.5K]
In this question, <span>q is the number of buggies the company can sell in a month if the price is $p per buggy. The revenue should be number of buggies sold(q) multiplied by the price(p). The equation would be:

revenue= p * q
revenue= p * (-4p + 616)= -4p^2 + 616p

The maximum revenue should be in the peak of the graph. The calculation would be:
</span>-4p^2 + 616p
-4*2 p^2-1 + 616*1 p^1-1=0
<span>-8p + 616=0
8p= 616
p=77

Put p=77 in the revenue equation would result
</span>revenue= -4p^2 + 616p
revenue= -4(77^2) + 616(77) = -23716 + 47432= $23716

Angle 8 = 84 degrees because Angle 2 and Angle 8 are inside opposite which makes them equivalent.

Angle 5 = 96 degrees because 180-84=96

Evaluate the surface integral. s x ds, s is the part of the plane 6x + 3y + z = 6 that lies in the first octant.
Musya8 [376]
The plane has intercepts at (1, 0, 0), (0, 2, 0), and (0, 0, 6), so we can parameterize the surface \mathcal S by

\mathbf r(u,v)=((1,0,0)(1-u)+(0,2,0)u)(1-v)+(0,0,6)v
\mathbf r(u,v)=((1-u)(1-v),2u(1-v),6v)

where 0\le u\le1 and 0\le v\le1. Now

\|\mathbf r_u\times\mathbf r_v\|=2\sqrt{46}(1-v)

so the surface integral reduces to

\displaystyle\iint_{\mathcal S}x\,\mathrm dS=2\sqrt{46}\int_{v=0}^{v=1}\int_{u=0}^{u=1}(1-u)(1-v)^2\,\mathrm du\,\mathrm dv=\frac{\sqrt{46}}3
