Answer:

So the correct answer is"none of the above".

Step-by-step explanation:

z+(z+6)=z+z+6=2z+6. \\ \\ (z+z)+(z+6)=z+z+z+6=3z+6. \\ \\ (z+6)+6=z+12 \\ \\

Given that ABCD is a rhombus, what is the value of x?

Sphinxa [80]

Answer:

x is 29

Step-by-step explanation:

In a rhombus diagonals bisect perpendicularly.

let the centre point of the rhombus be O.

By seeing the diagram we can say that Angle DBC is congruent to angle ADB.

We can say they are congruent because they are symmetric about the diagonals and also by the principle of parallel lines.

Also ADB is a right angled triangle so ,

$x+(3x-26)=90$

$4x=116\\ x=29$

Hence the value of x is 29.

Use the shell method to find the volume of the solid generated by revolving the regions bounded by the curves and lines about th

RSB [31]

Answer:

The volume of the solid is:

$\displaystyle\frac{19\pi}{6}$

Step-by-step explanation:

See the graph of the region attached.

To find the intersection between the line and the parabola we set the equation equal to each other, and solve that quadratic equation by factorization:

$x^2=9-8x\\x^2+8x-9=0\\(x+9)(x-1)=0\\x=-9,x=1$

Since the region is the one for $x\ge 0$ then the intersection we are interested on is x=1 as it can also be seen in the graph.

Then we set the integral using shell method for revolving about the y-axis:

$\displaystyle\int_a^b 2\pi\,x\,h(x)\,dx$

Where h(x) is the height of the shell which here is the distance between the parabola and the line, so $8x-9-x^2$ (since the line is on the top we subtract from it the parabola)
