Hey there! Let's figure this question out for you!

A math conjugate, is formed by changing the sign between two terms in a binomial.

An example would be:

4+7x would become 4 - 7x.

I hope this helps!

Suppose a right cylinder was bent into a U-shape and was compared to another right cylinder. What can be said about their volume

xenn [34]

Answer:

The volume of the U-shape will be<u> half </u>the volume of the original right cylinder.

Step-by-step explanation:

If we are given a right cylinder and it was bent into a U shaped then this U-shaped figure could also be considered as a half cylinder.

We could see from the figure attached how this shape looks like.

and now the volume of this half cylinder will be half the volume of the actual right cylinder.

Answer:

-2040

Step-by-step explanation:

$S_n=a_1\dfrac{r^n-1}{r-1} \qquad\text{for first term $a_1$ and common ratio r}\\\\S_8=-8\dfrac{2^8-1}{2-1}=-2040$

The sum of the first 8 terms is -2040.

Perform the specified operations on the polynomials: Subtract 2x2−3xy+4y2from 3x2−5xy−6y2

tankabanditka [31]

Answer:

Solution to the given expression is $(x^2 -10y^2 -2xy)$

Step-by-step explanation:

Here, the given expression are:

$P(x) = 2x^2- 3xy+4y^2\\Q(x) = 3x^2 - 5xy-6y^2$

To Solve for : Q(x) - P(x)

Now substitute the value of P(x) and Q(x) , we get:

$Q(x) - P(x) = P(x) = (3x^2 - 5xy-6y^2) - (2x^2- 3xy+4y^2)\\= 3x^2 - 5xy-6y^2 - 2x^2+3xy-4y^2\\=x^2-10y^2-2xy\\\implies Q(x) - P(x) = (x^2-10y^2-2xy)$

Hence solution to the given expression is $(x^2 -10y^2 -2xy)$
