An obtuse because a 40• angle is acute and 90• angle is regular so it is obtuse

It would be obtuse because an obtuse angle is anything over 90 degrees.  90+40=130.  Therefore, since 130 is greater than 90, it is an obtuse angle

Evaluate the triple integral. 5x dv, where e is bounded by the paraboloid x = 7y2 + 7z2 and the plane x = 7. e
Mrac [35]

Convert to cylindrical coordinates:

x=x

y=r\cos\theta

z=r\sin\theta

Then E is the set of points (r,\theta,x) such that 0\le r\le1, 0\le\theta\le2\pi, and 7y^2+7z^2\le x\le7 or 7r^2\le x\le7.

Now

\displaystyle\iiint_E5x\,\mathrm dV=5\int_0^{2\pi}\int_0^1\int_{7r^2}^7xr\,\mathrm dx\,\mathrm dr\,\mathrm d\theta=\boxed{\frac{245\pi}3}

PLEASE HELP ME WITH THIS!!

Answer:

86.9 cm squared

Step-by-step explanation:

The surface area of a rectangular prism is denoted by: A=2lw+2lh+2wh, where l is the length, w is the width, and h is the height.

Here, the length is l = 5.3, the width is w = 2, and the height is h = 4.5. So, plug in these values:

A=2lw+2lh+2wh=2*5.3*2+2*5.3*4.5+2*2*4.5=86.9

Thus, the surface area is 86.9 cm squared.

Hope this helps!
