6*(5.2)/2 + 3*[6*(8.3)/2]
To find the vertex of the parabola, we need to write it in a vertex form.
y=x² - 8x +12
1) complete the square
y=
x² - 8x +12
y =
x² -2*4x + 4² - 4² +12
y=
(x-4)² -16 +12
2) calculate and write a vertex
y=
(x-4)² -16 +12
y=
(x-4)² - 4
(x-4) ----- x- coordinate of the vertex x=4
y=(x-4)²
- 4 -------y- coordinate of the vertex y = - 4 Vertex is (4, -4).
Answer is (4, -4). No correct answer is given in choices.
We can solve this problem by first solving for the total
volume of the cube. The formula for volume of cube is given as:
V cube = s^3
Where s is the length of one side which is equivalent to
2 inches. Therefore:
V cube = (2 inches)^3
V cube = 8 cubic inch
Assuming that all the pebble fills the cube without any
spaces, then the total weight of the pebbles in the cube would simply be:
Total weight = 0.5 lb per cubic inch * 8 cubic inch
Total weight = 4 lb
Therefore, the total weight of the pebbles in the cube is <u>4
lbs</u>.
Answer:
24
Step-by-step explanation:
haha i had a test with the same question, i promise its correct :)
<span>The correct answer is the Option "A": Integer. Then, the text is: "Whenever the solution to a system does not have integer coordinates, it can be difficult or impossible to find the precise answer through graphing."
By definition, the numbers called "Integers" are all the positive numbers (which are known as</span> <span>"Natural numbers"), all the negative numbers and the zero (0) and they are identified with the letter "Z":
Z= </span>{-∞...-3,-2,-1,0,1,2,3...+∞}<span>
