1 answer:
Illusion [34]3 years ago
4 0

Answer:

{x}^{4}  -  {x}^{3} -  {9x}^{2}   -  {11x}^{2} - 4

Step-by-step explanation:

Since the roots are -1,-1,-1 and 4 we can that as.

(x + 1)(x + 1)(x + 1)(x - 4)

x+1=0, x equal -1, and x-4=0 and x equal 4. Then apply the foil method to one at a time and you equal the answer above.

A cyliner has a radius of 16 m and a height of 24m. what is the approximate volume of this cylinder? (use �� = 3.14.)
vovikov84 [41]
<span>Cylinder Volume   =   </span><span>π <span>• r² • height
</span></span><span>Cylinder Volume   =   3.14 * 16^2 * 24
</span>Cylinder Volume   = <span> <span> <span> 19,292.</span></span></span>  cubic meters
My answer is much too big for those choices.

So, I'm guessing that 16 meters is the diameter.
If that's the case, radius = 8 meters and
Cylinder Volume   =   3.14 * 8^2 * 24
<span>Cylinder Volume   =   3.14 * 64 * 24
</span>Cylinder Volume   =   <span> <span> <span> 4,823.04 </span> </span> </span> cubic meters
So answer is "c"

Can someone answer this please??
anyanavicka [17]

  volume of A = 1728

volume of B = 729  

<span> (1728 / 729) = (a / b)^3  (a = width of A, b = width of B)
  a / b = cube root (1728 / 729)  = 4/3   </span><span> b = 10 (given)
a / 10 = 4/3 </span><span>
  a = 40/3 = 13.33333</span>
 so width of A is 13.33m

What is the expression for 5.802
Reptile [31]

Answer:

Step-by-step explanation:

Unsure of what you want.  If you want to express 5.802 in words, you get "five plus 802 thousandths."

If you want to break down 5.802 into an equivalent numerical expression, you get 5 + 8/10 + 2/1000, or

5 + 4/5 + 1/500
