The formula for volume of a prism is V = Bh.

Misha Larkins [42]

Hello, 3Coli here!

Here is the answer to your question:

The variable B stands for the area of the base.

In this prism, B equals 38.5 in.^2

The variable H stands for height.

In this prism, h is 9 in.

The volume of the prism is 346.5 in.^3

Hopefully, this helps! :D

Good luck with your assignment.

Use completing the square to determine which of the following gives the solutions to 3x2 - 24x + 40 = 28.

jeka94

Answer:

$x=4+2\sqrt{3}$

$x=4-2\sqrt{3}$

Step-by-step explanation:

<u>Completing the square</u>

when $ax^2+bx+c=0$

Given equation:

$3x^2-24x+40=28$

Subtract 40 from both sides:

$\implies 3x^2-24x=-12$

Divide both sides by 3:

$\implies x^2-8x=-4$

Add the square of half the coefficient of $x$ to both sides:

$(\frac{b}{2})^2=(\frac{-8}{2})^2=16$

$\implies x^2-8x+16=-4+16$

Factor the left side and simplify the right side:

$\implies (x-4)^2=12$

Square root both sides:

$\implies x-4=\pm\sqrt{12}$

Add 4 to both sides and simplify the radical:

$\implies x=4\pm\sqrt{4 \cdot 3}$

$\implies x=4\pm\sqrt{4}\sqrt{3}$

$\implies x=4\pm2\sqrt{3}$

Use the remainder Theorem to find the remainder for the given division. (16z^4-1)/(z+1)

Mice21 [21]

Remainder Theorem: when a polynomial <em>P(x) </em>is divided <em>by (x - a), </em>the remainder is <em>P(a).</em>

<em />

Given expression:

$\frac{16z^{4}-1}{z+1}$

In this case:

$P(z)=16z^4-1$ $z=-1$

To know the reminder, we have to plug in the value of <em>z </em>in the polynomial:

$P(-1)=16(-1)^4-1$

Simplifying:

$P(-1)=16(1)^{}-1$ $P(-1)=16^{}-1$ $P(-1)=15$

Answer: The remainder is 15.
