Mathematics

Tom [10]4 years ago
5 0

Answer:

x = -3, 2, 3.

Step-by-step explanation:

f(x )= x^3 - 2x^2 - 9x + 18      We factor this by grouping:

f(x) = x^2(x - 2) - 9(x - 2)

f(x) = (x ^2- 9)(x - 2)

f(x) = (x - 3)(x + 3)(x - 2).

The zeroes of the function are:

x = -3, 2, 3.

Volume of this prism ​
Lyrx [107]

The volume is (area of cross-section) x (length) .

-- The cross-section is a triangle.  The area of a triangle is

Area = (1/2) (base) (height) .

In this one, the base is 9/4 m and the height is 3-1/3 m .

Area = (1/2) (9/4 m) (3-1/3 m)

Area = (1/2) (9/4) (10/3)

Area = 90/24 m² .

-- Volume = (area of cross-section) x (length)

Volume = (90/24 m²) x (7-1/3 m)

Volume = (90/24) x (22/3) m³

Volume = (1,980 / 72) m³

<em>Volume = 27.5 m³  </em>

Maxi is trying to stack books on a shelf that is 18 inches tall. If the books are each 4/5 inch thick, how many can she stack?
kari74 [83]
I believe it should be 22½ or 22 books

You would need to divide 18 and ⅘

18 ÷ ⅘ = 22½

I hope this helps, even though I’m not totally sure :)

The answer to explain how to find 4 x 8 show your work
Effectus [21]
4 multiplied by 8 would be 32. I know this because if you have one group of 8, and add 3 more, and you sat down to count, you would get 32. Also, 8 plus 8 plus 8 plus 8 is 32.
