The volume would be twice the original since the base area gets doubled. <span><span>13</span>×(BaseArea)×Height</span> Now, twice the Base Area would be : <span><span>13</span>×(2)(BaseArea)×Height</span><span> So, the entire thing gets doubled on the other side as well. Which means that 20 cubic units becomes 40 cubic units.</span>

What are the domain and range of the function f(x)=-3(x-5)squared+4
svet-max [94.6K]
Domain is all real numbers
range
hmm
we know that x^2=a positive number
then multiply it by that negative -3
therefor the range is going to be mostly negative
if we make the x-5  equal to zero, then there is no negative, so
wher x=5, then f(5)=0+4=4
the highest positive number you can get is f(5)=4

so therfor

domain=all real number
range is x≤4

KonstantinChe [14]

Answer: 12, 15, 11, 28

Explanation:

14. FC is half of AC so the length of FC is 12.

15. BD is 30 and half of that is BC or 15. AB and BC have same length so it is also 15.

16. ED and BE have same length so it is also 11.

17. BD is twice of AB so if AB is 14, BD will be 28.

Would appreciate a brainly <3

The area of a square bedroom is 144 square feet. what is the length of one wall?
Rufina [12.5K]
The answer is:  "12 feet" .
________________________________
Note:  In a square, the length of EACH of the four sides of the square is the same.

Area = Length * width. 

For a square, length = width.

So for a square, Area = length * width = (length of a side)² = s² ,

Given:  A = s² = 144 ft² ;

Solve for the positive value of "s" .
________________________________
  →  s² = 144 ft² ;  Take the "square root" of each side ;

  → √(s²) = √(144 ft²) ;

  →   s = 12 ft.
_______________________________
The answer is:  12 ft.
