A solid oblique pyramid has a square base with edges measuring x cm. The height of the pyramid is (x + 2) cm. Which expression r

zavuch27 [327]

we know that

the volume of a solid oblique pyramid is equal to

$V=\frac{1}{3}*B*h$

where

B is the area of the base

h is the height of the pyramid

in this problem we have that

B is a square

$B=b^{2}$

where

$b=x\ cm$

$B=x^{2}\ cm^{2}$

$h=(x+2)\ cm$

substitute in the formula of volume

$V=\frac{1}{3}*x^{2}*(x+2)\\ \\V=\frac{1}{3}*[x^{3} +2x^{2}]\ cm^{3}$

therefore

the answer is

$V=\frac{1}{3}*[x^{3} +2x^{2}]\ cm^{3}$

Calculate the line integral of the vector field F = xy i + (x − y) j along C, the triangle composed of three segments. C1 is

Ksivusya [100]

Thank you for posting your question here at brianly. I hope the answer will help you. Below is the solution:

or segment from (4,0) to (-4,0), y is always zero because straight segment.
in that case x*y=x*0=0 
and x+y=x+0=x 
if you choose x=4-t where t goes from 0 to 8 you should get 
r(t)=0i+(4-t)j
